China’s two largest battery manufacturers, CATL and BYD, are targeting 2027 for small-scale production of solid-state batteries, a technology that promises to push single-charge EV ranges toward the 1,000-mile threshold. That timeline now runs alongside a tightening regulatory framework: a mandatory national safety standard designated GB38031-2025 will take effect on July 1, 2026, imposing strict “no fire/no explosion” requirements on EV batteries sold in the country. Together, these parallel tracks set up a high-stakes test of whether China can deliver on ambitious range claims while meeting some of the world’s toughest battery safety rules.
Solid-State Production Targets From CATL and BYD
Solid-state batteries replace the liquid electrolyte found in conventional lithium-ion cells with a solid material, which can store more energy per unit of weight and volume. That density gain is the technical basis for projections that future EVs could travel far beyond the 300-to-400-mile range typical of today’s top-tier models. According to a State Council Information Office report, Chinese battery giants CATL and BYD have set 2027 as their target for initial small-scale production of these cells. Both companies already dominate global EV battery supply chains, so even a limited production run could reshape expectations across the industry.
The 2027 goal, however, is explicitly for small-scale output, not mass-market rollout. That distinction matters. Solid-state cells have been demonstrated in labs and limited prototypes for years, but scaling them to millions of units while keeping costs competitive with liquid-electrolyte packs remains an unsolved engineering challenge. Cathode cracking, interface resistance between solid layers, and manufacturing yield rates have all slowed prior commercialization attempts by companies in Japan, South Korea, and the United States. What separates the Chinese push is the sheer capital and government coordination behind it. Both CATL and BYD operate with significant state backing, and Beijing has signaled through policy documents that next-generation battery technology is a strategic priority. If the 2027 window holds, even a modest volume of solid-state packs entering real vehicles would generate the road data needed to validate or challenge the range projections that have circulated for years.
New Safety Standard Raises the Bar Before Solid-State Arrives
Before those batteries reach consumers, they will have to clear a regulatory hurdle that did not exist a year ago. The mandatory national safety standard GB38031-2025 takes effect in mid-2026, according to China’s State Council. The standard introduces requirements described as “no fire/no explosion” related, meaning battery packs must demonstrate that they will not ignite or rupture under a defined set of stress conditions. This is a significant escalation from earlier Chinese battery safety rules, which focused primarily on thermal runaway containment rather than outright prevention of fire events.
GB38031-2025 also adds new testing protocols, including bottom impact tests and post-fast-charge-cycle testing. Bottom impact testing simulates road debris strikes to the underside of a battery pack, a real-world failure mode that has contributed to EV fires globally. Post-fast-charge-cycle testing evaluates whether repeated use of high-speed charging degrades a pack’s safety margins over time. Both additions reflect lessons learned from incidents involving conventional lithium-ion batteries. For solid-state developers, these tests could actually play to the technology’s strengths: solid electrolytes are inherently less flammable than their liquid counterparts, and they tend to be more resistant to thermal runaway. But passing a lab test and surviving years of real-world abuse are different things, and the standard will apply equally to all battery chemistries sold in China.
Regulation as Competitive Advantage, Not Just Compliance
The timing of GB38031-2025 relative to the solid-state production targets creates an interesting dynamic. By July 2026, every EV battery entering the Chinese market must meet the new safety floor. By 2027, CATL and BYD aim to begin producing solid-state cells. That one-year gap means the regulatory framework will already be in place when the first solid-state packs are ready for vehicles, forcing manufacturers to design for compliance from day one rather than retrofitting safety features after launch. This sequencing is likely deliberate. Beijing has a track record of using technical standards to shape industrial outcomes, and setting a high safety bar just ahead of a new technology wave gives domestic producers a built-in credibility signal for export markets.
That credibility matters because China’s EV ambitions extend well beyond its own borders. European and Southeast Asian markets are already absorbing growing volumes of Chinese-made electric vehicles, and battery safety has been a persistent concern among regulators and consumers in those regions. If Chinese solid-state batteries can demonstrate compliance with a standard that explicitly demands no fire and no explosion outcomes, it becomes harder for foreign regulators to impose additional barriers on safety grounds alone. The strategic calculus here is straightforward: build the toughest domestic standard, prove your batteries meet it, and then use that certification as a passport for global sales. The broader policy approach is visible in other areas as well, where official documents and regulations, often compiled through central government channels, are used to align industrial policy, export strategy, and technology development under a single framework.
What the Range Promise Actually Requires
The near-1,000-mile range figure that has circulated in connection with solid-state batteries deserves careful scrutiny. Energy density improvements from solid electrolytes are real and well-documented in research settings, but translating lab-grade energy density into on-road range involves a chain of variables that no single battery chemistry can control. Vehicle weight, aerodynamics, tire resistance, climate conditions, driving speed, and cabin heating or cooling loads all eat into theoretical range. A battery pack that delivers exceptional energy density on a test bench may still fall short of headline-grabbing numbers once it is integrated into a full vehicle platform with safety margins, structural reinforcements, and real-world driving patterns.
To approach 1,000 miles on a single charge, automakers would likely need to combine high-energy solid-state cells with aggressive vehicle efficiency measures and potentially larger pack sizes. That introduces trade-offs. Larger packs add cost and weight, which can erode efficiency gains and push vehicles into higher price brackets. At the same time, ultra-long-range vehicles may not align with typical daily driving needs, raising questions about whether consumers will pay a premium for capability they rarely use. In practice, the first generation of solid-state-equipped EVs in China may target more modest but still meaningful improvements (such as pushing mainstream models into the 500-to-700-mile range under standard test cycles) while using the technology’s safety and fast-charging advantages as additional selling points.
China’s High-Stakes Battery Balancing Act
China’s solid-state push and the rollout of GB38031-2025 together amount to a carefully staged experiment in industrial policy. On one side is a technology bet: that solid-state batteries can be brought from pilot lines to commercial vehicles quickly enough to sustain China’s lead in EV supply chains. On the other is a regulatory bet: that imposing some of the world’s strictest battery safety rules will not slow innovation but instead force manufacturers to solve safety and performance challenges in parallel. The interaction between these two bets will determine whether the promised leap in range and safety materializes on the road or remains confined to laboratory demonstrations and concept cars.
If CATL and BYD meet their 2027 small-scale production targets under the new safety regime, they will not only validate years of research investment but also set a powerful precedent for how emerging technologies can be guided by proactive regulation. Success would strengthen China’s hand in global EV negotiations, giving its automakers and battery suppliers a compelling narrative around both performance and safety. Failure, by contrast, would highlight the difficulty of simultaneously pushing the frontier of energy density and tightening safety expectations. Either way, the coming few years will offer one of the clearest tests yet of whether ambitious technology roadmaps and stringent standards can be aligned to accelerate, rather than constrain, the next generation of electric vehicles.
