company news about What stage has the mass production of solid-state batteries reached in 2026

In March 2026, solid-state batteries officially entered the mass production and vehicle integration phase, marking a pivotal turning point in the industry landscape. Many observers intuitively assumed that solid-state batteries would directly render internal combustion engine (ICE) vehicles obsolete. However, according to the latest data and industry developments released by authoritative bodies—such as the Ministry of Industry and Information Technology (MIIT) and the China Automotive Technology & Research Center (CATARC)—the first segment to face disruption and displacement will not be ICE vehicles. Instead, it will be low-to-mid-range new energy vehicles (NEVs) that rely on traditional liquid lithium-ion batteries, follow outdated technical pathways, and lack core competitiveness.

I. Authoritative Confirmation: The Actual Status of Solid-State Battery Mass Production in 2026

Let us first lay out the official information clearly, avoiding mere conceptual speculation. In March 2026, the MIIT and CATARC jointly released the *White Paper on the Progress of Solid-State Battery Industrialization*. This document explicitly states that China has entered a critical phase characterized by the scaled mass production of hybrid solid-liquid batteries (formerly referred to as "semi-solid-state") and the pilot-scale verification of all-solid-state batteries. 

- **Hybrid Solid-Liquid Batteries:** By 2026, deliveries had reached the thousand-unit level. Battery cell energy density ranges from 350 to 400 Wh/kg; vehicle range (under CLTC standards) generally exceeds 1,000 kilometers; charging to 80% capacity takes just 10 minutes; and capacity retention at ultra-low temperatures of -30°C exceeds 85%. Models such as the NIO ET9, GAC Aion Hyper series, and Zeekr 001 FR have been confirmed for small-batch vehicle integration in the fourth quarter of 2026.

- **All-Solid-State Batteries:** Leading enterprises—including Chery, BYD, and CATL—have established pilot production lines. Yield rates have stabilized at over 92%; single-cell energy density has surpassed 500 Wh/kg, reaching a peak of 600 Wh/kg; the technology supports 5C ultra-fast charging; and the batteries exhibit no thermal runaway during nail penetration or extrusion tests. Large-scale demonstration deployments in vehicles are scheduled to commence in 2027, with the technology expected to penetrate the 200,000-yuan-class family car market by 2030. - **Policy Support:** The world's first national standard for automotive solid-state batteries—*Solid-state Batteries for Electric Vehicles Part 1: Terminology and Classification* (GB/T 43568-2026)—is set to be implemented in July 2026. This standard clearly delineates three categories of batteries—liquid-electrolyte, hybrid solid-liquid, and all-solid-state—thereby putting an end to the chaos surrounding "pseudo-solid-state" products. Eight government agencies have established a dedicated subsidy fund of 10 billion RMB to prioritize support for companies engaged in the mass production of solid-state batteries; these companies will benefit from a reduced corporate income tax rate of 15% for three years and will have their production capacity approvals fast-tracked via a "green channel."

These data demonstrate that solid-state batteries have transitioned from a laboratory concept into an industrial reality. They comprehensively outperform traditional liquid-electrolyte batteries, and their mass production roadmap is clearly defined, with robust policy safeguards firmly in place.

**II. A Hardcore Comparison: Solid-State vs. Traditional Liquid-Electrolyte Batteries—The Gap Is Crystal Clear**

Traditional liquid-electrolyte lithium batteries (specifically ternary lithium and lithium iron phosphate chemistries) currently dominate the new energy vehicle market, yet they are fast approaching their performance ceiling.

- **Energy Density:** Mainstream liquid-electrolyte batteries offer 150–220 Wh/kg; hybrid solid-liquid batteries reach 350–400 Wh/kg; and all-solid-state batteries achieve 450–600 Wh/kg—representing a 1.8- to 2.7-fold increase over liquid-electrolyte batteries. For a battery of the same weight, a solid-state version can store nearly double the amount of energy, effectively doubling the vehicle's driving range.

- **Safety:** Liquid electrolytes are flammable and prone to thermal runaway in extreme scenarios. Solid-state batteries, conversely, utilize non-flammable solid electrolytes; they exhibit zero instances of fire during rigorous tests such as nail penetration and exposure to high temperatures, and their thermal runaway threshold exceeds 350°C—marking a safety improvement of over tenfold.

- **Charging Speed:** Mainstream liquid-electrolyte batteries typically charge at a rate of 1–2C, reaching 80% capacity in 30–60 minutes. Solid-state batteries, however, support ultra-fast charging rates of 5–6C, replenishing 80% of their energy in just 10 minutes—a speed comparable to refueling a gasoline-powered vehicle.

- **Low-Temperature Performance:** At -20°C, the driving range of liquid-electrolyte batteries typically shrinks by 30%–50%. Solid-state batteries, by contrast, retain over 85% of their capacity at -30°C, ensuring that driving range remains undiminished even during the harsh winters of northern regions. - **Cycle Life:** Liquid-electrolyte batteries offer 1,000–1,500 cycles; hybrid solid-liquid batteries exceed 3,000 cycles; and all-solid-state batteries surpass 5,000 cycles—achieving a lifespan 2 to 3 times longer than that of liquid-electrolyte batteries.

- **Cost Trends:** By 2026, the cost of hybrid solid-liquid batteries is projected to be approximately 0.6 RMB/Wh, on par with high-end ternary lithium batteries. By 2027, the cost of all-solid-state batteries is expected to drop to 0.5 RMB/Wh, with the potential to fall below that of liquid-electrolyte batteries by 2030.

**In Summary:** Solid-state batteries comprehensively outperform traditional liquid-electrolyte batteries across five core metrics—range, safety, fast charging, low-temperature performance, and lifespan—making them the "ultimate battery solution" for new energy vehicles.

**III. The Truth: What Will Be Eliminated First Is Not the Fuel-Powered Car, But a Specific Type of New Energy Vehicle**

Many people harbor a misconception: that the arrival of solid-state batteries spells the end for fuel-powered cars. However, the industry logic suggests the exact opposite: the primary target of solid-state batteries' impact will be the obsolete production capacity *within* the new energy vehicle sector itself, rather than fuel-powered cars.

**1. The Living Space for Fuel-Powered Cars Will Not Be Squeezed Out in the Short Term**

- Fuel-powered cars possess a mature supply chain, an established refueling network, and ingrained user habits; furthermore, they retain irreplaceable advantages in scenarios involving long-distance travel, off-roading, and low-temperature environments.

- In the first quarter of 2026, the market share of fuel-powered cars is expected to remain around 45%. In specific segments—such as lower-tier markets, extremely cold regions, and long-haul freight transport—their market share is projected to exceed 60%. The total vehicle fleet in China stands at approximately 366 million units, of which over 320 million are fuel-powered cars, accounting for nearly 88% of the total.

- The Ministry of Industry and Information Technology (MIIT) has explicitly stated that China's automotive market will maintain a long-term coexistence of multiple technological pathways. The government respects market choices and will not implement a "one-size-fits-all" policy to eliminate fuel-powered cars. In their initial phase, solid-state batteries will primarily target high-end vehicle models; they are not expected to filter down to the mass-market passenger vehicle segment until 2030. Consequently, their impact on fuel-powered cars will be gradual and evolutionary, rather than sudden and disruptive. 2. Mid-to-Low-End New Energy Vehicles Powered by Liquid Batteries Are the Primary Candidates for Elimination

The mass production of solid-state batteries will directly trigger an internal shakeout within the new energy vehicle (NEV) industry, with three specific categories of vehicles being the first to be displaced:

- Entry-level NEVs with a range of less than 500 kilometers that rely on low-end lithium iron phosphate (LFP) batteries: Once solid-state batteries become widespread, a 1,000-kilometer range will become the industry standard, rendering models with a range of less than 500 kilometers uncompetitive.

- Automakers with outdated technological roadmaps and no strategic layout for solid-state batteries: Leading enterprises (such as BYD, CATL, Chery, etc.) have already secured solid-state battery production capacity, with large-scale vehicle integration set to begin in 2027. Small and medium-sized automakers that fail to keep pace will be rapidly eliminated.

- NEVs that rely on "low-price cutthroat competition" and lack core technological capabilities: Solid-state batteries deliver significant performance upgrades; consequently, consumers will be more willing to pay a premium for extended range and enhanced safety, leaving low-priced, low-quality models with no viable market space.

Data released by the China Automotive Technology & Research Center (CATARC) in March 2026 indicates that following the successful mass production and deployment of solid-state batteries, it is projected that between 2027 and 2028, more than 30% of mid-to-low-end NEVs powered by liquid batteries will be eliminated, leading to a substantial increase in industry concentration.

IV. Industry Logic: Why an Internal Shakeout, Rather Than the Elimination of Fuel-Powered Vehicles?

1. The Generational Technology Gap Is the Core Logic Behind the Elimination Process

Solid-state batteries are not merely an "upgraded version" of liquid batteries; rather, they represent a fundamental technological innovation at the foundational level.

- The performance of traditional liquid batteries has already reached its ceiling, leaving limited room for further improvement; solid-state batteries, however, shatter this ceiling directly, achieving a comprehensive leap forward in terms of driving range, safety, and fast-charging capabilities.

- Automakers that possess solid-state battery technology effectively hold a "ticket to the next generation" of the industry; conversely, those that have failed to establish a strategic layout in this area will be confined to engaging in cutthroat competition within the old technological paradigm, ultimately facing elimination.

2. The Reversal in Cost Dynamics Will Accelerate the Phasing Out of Obsolete Production Capacity

Prior to 2026, the high cost of solid-state batteries made them an exclusive feature of high-end vehicles; however, as mass production scales up and key materials undergo localization, costs are expected to decline rapidly. - By the end of 2026, the cost of hybrid solid-liquid batteries is projected to reach parity with high-end ternary lithium batteries; by 2027, the cost of all-solid-state batteries is expected to fall below that of liquid-electrolyte batteries; and by 2030, solid-state battery costs are projected to be 15%–20% lower than those of liquid-electrolyte batteries.

- Once this cost advantage is established, solid-state batteries will rapidly displace liquid-electrolyte batteries, causing low-to-mid-range liquid-battery vehicle models to lose their price competitiveness.

3. Policy Orientation: Prioritizing Support for Technological Leaders

Policy directives for 2026 are clear: accelerate breakthroughs in solid-state battery technology and curb the destructive "race to the bottom" pricing competition within the new energy sector.

- A dedicated subsidy fund of 10 billion RMB, a "green channel" for production capacity approvals, and tax incentives will all be directed preferentially toward enterprises engaged in the mass production of solid-state batteries.

- Following the implementation of new national standards, "pseudo-solid-state" and "low-quality liquid-electrolyte" products will be purged from the market, accelerating the consolidation of the industry around leading players.

- In 2026, subsidy policies for new energy vehicles will be upgraded; models equipped with solid-state batteries (featuring an energy density of ≥400 Wh/kg) will qualify for cumulative subsidies of up to 15,000 RMB per vehicle, thereby further driving technological advancement.

V. Impact on Consumers: The Logic of Car Buying Has Fundamentally Changed

The mass production of solid-state batteries will not only reshape the industry landscape but also fundamentally alter how consumers make their car-buying decisions.

- No more range anxiety: A driving range of 1,000+ kilometers will become the standard, eliminating the need to constantly search for charging stations during long-distance travel.

- Enhanced safety assurance: With zero risk of thermal runaway, battery safety concerns—a major source of consumer anxiety—will be completely resolved.

- Greater charging convenience: An 80% charge can be achieved in just 10 minutes, bringing the speed of "refueling" closer to that of pumping gasoline.

- Clearer purchasing choices: Consumers will prioritize automakers with established solid-state battery strategies and leading technological roadmaps, while avoiding brands that lack core technologies and rely solely on low-price competition to survive.

VI. Conclusion: Solid-State Batteries Are a "Shake-up Force" for the New Energy Sector, Not the "Terminator" of Fuel-Powered Vehicles

Returning to the initial question: Once solid-state batteries enter mass production, which products will be the first to be displaced?

The answer is clear: It will not be fuel-powered vehicles, but rather low-to-mid-range new energy vehicles that rely on traditional liquid lithium-ion batteries—models that are technologically backward and lack core competitive advantages.

The advent of solid-state batteries marks not the endpoint of the transition from fuel-powered to new energy vehicles, but rather the starting point for a new wave of internal technological upgrading within the new energy industry itself. Its purpose is to phase out outdated production capacity, drive technological advancement, and ultimately enable consumers to access safer, more convenient, and more efficient new energy vehicles.

Over the next 3 to 5 years, the new energy vehicle industry is poised to undergo a profound shakeout. Leading enterprises, leveraging their technological advantages in solid-state batteries, will further expand their market share; conversely, small and medium-sized automakers that fail to keep pace with these technological upgrades will gradually exit the market. Meanwhile, fuel-powered vehicles will continue to play a long-term role in specific scenarios—such as long-distance travel, off-roading, and extreme cold environments—establishing a pattern of complementary coexistence with new energy vehicles.

For the average consumer, there is no need to blindly wait for the arrival of fully solid-state batteries when purchasing a vehicle today. Instead, one can prioritize models equipped with hybrid solid-liquid batteries; this allows you to enjoy benefits such as extended range and fast charging, while simultaneously mitigating the risk of depreciation often associated with rapid technological iteration.
