The introduction of China’s new national solid-state battery standard is prompting an immediate reassessment of equipment assets across CATL and BYD production lines. Set to take effect on July 1, GB/T 43568-2026 defines clear chemical thresholds for solid-state classifications, exposing an inflated valuation of projected manufacturing infrastructure across the broader supplier network, as reported by 21Jingji.
The standard mandates that batteries containing between 5% and 20% liquid electrolyte be classified as hybrid systems. True all-solid-state cells must have less than 5% liquid electrolyte and meet specific thermal mass stability under vacuum conditions. These strict boundaries are affecting near-term procurement decisions for assembly equipment.
Conventional lithium-ion machinery is highly compatible with the hybrid architectures intended for near-term vehicle production. Industry evaluations show that existing factory lines can process these semi-solid variations with less than 10% equipment modifications. This technical overlap directly reduces the immediate need for a complete overhaul of assembly systems.
Initial capital outlays for specialized all-solid-state manufacturing lines currently range from 400 million yuan (59.02 million USD) to 500 million yuan (73.78 million USD) per GWh. Industrial projections suggest these equipment costs will decrease to 200 million yuan (29.51 million USD) by 2030. Dongfeng is targeting mass production of hybrid packs, leveraging existing floor space to optimize near-term capital expenditure.
Sulfide-based pilot operations deployed by tier-one manufacturers are focusing on interface stability rather than capacity expansion. Recent disclosures from CATL executives confirm that the commercial viability of all-solid-state batteries remains constrained by engineering bottlenecks. Meanwhile, academic research, such as the Chinese Academy of Sciences’ electrolyte studies, emphasizes that solid-state interfaces require prolonged cycling validation before automated scale-up is feasible.
Market analysts had previously projected that next-generation line transitions would create a 59.2 billion yuan (8.73 billion USD) machinery demand. This forecast now faces structural adjustments as conventional liquid batteries continue to dominate monthly installations. Pilot projects, such as Eve Energy assembling 60 Ah units and Gotion High-tech designing a 2 GWh facility, primarily serve as technical baselines.
Monthly installation data from China EV DataTracker shows CATL maintaining market leadership with 33.08 GWh, representing a 46.7% market share. BYD secured second place with 11.87 GWh (16.8% share), followed by Gotion High-tech at 4.44 GWh. CALB recorded 4.3 GWh (6.1% share), while Eve Energy registered 3.23 GWh (4.6% share).
These volume trends confirm that existing liquid-cell manufacturing assets dominate the industrial landscape. Equipment procurement strategies must align with the gradual adoption of hybrid systems before true all-solid-state integration transforms the broader supply chain. The incoming July 1 regulation provides a realistic framework that grounds machinery market expectations within current battery chemistry capabilities.
