Li Auto targets solid-state battery small-batch production by 2027-2028, cites lifespan and cost hurdles
Li Auto is advancing multiple solid-state battery projects, with small-batch production capability expected by 2027 or 2028, according to Senior Director Liu Zhimin. Prototype validation has been completed in eyewear products, but mature mass production for vehicles is estimated to take another five years due to challenges in lifespan, charging performance, and cost. Separately, the company has deployed self-developed batteries across models including the Li L6, L8, and i8, aiming for full lineup coverage.

Li Auto Details Self-Developed Battery Strategy: Aims for Data Integration, Not Cost Reduction
Li Auto has detailed its self-developed battery strategy, revealing that the project was initiated in 2020 after the success of the Li ONE. President Ma Donghui stated the goal is not cost reduction but achieving 'three integrations':打通底层数据 (connecting underlying data) for safety, 打通整车体验 (connecting vehicle experience) for performance, and 打通维修标准与售后服务 (connecting repair standards and after-sales service). The company has defined clear boundaries: it will self-develop and manufacture battery packs (PACK), while adopting a 'self-developed, outsourced manufacturing' model for cells, partnering with欣旺达 (Sunwoda) and 中创新航 (CALB). Li Auto's next major target is 15C ultra-fast charging, aiming to reduce charging time to the '5-minute level,' with prototype vehicles already in road testing. Regarding solid-state batteries, executives estimate mass production for passenger vehicles is unlikely before 2032, with penetration below 1% initially, though the company continues to track the technology.

Li Auto has detailed its self-developed battery strategy, revealing that the project was initiated in 2020, shortly after the Li ONE launch. President Ma Donghui stated the goal is not cost reduction but achieving 'three integrations':打通底层数据 (bottom-level data) for safety and quality, 打通整车体验 (vehicle experience) for performance and longevity, and 打通维修标准与售后服务 (repair standards and after-sales service) for consistent user experience. The company has defined clear boundaries: battery packs (PACK) are self-developed and self-manufactured due to their tight coupling with vehicle systems and role as the carrier for data integration via the BMS. Cells are self-developed but manufactured by partners like Sunwoda and CALB under a 'self-developed, outsourced manufacturing' model, similar to chip design firms using TSMC. Li Auto has invested strategically in Sunwoda, becoming its second-largest shareholder. The company's next major target is 15C ultra-fast charging, aiming to reduce charging time from 10 minutes to 5 minutes, with prototype vehicles already road-testing. Regarding solid-state batteries, executives estimate mass production for passenger vehicles is still over five years away, with penetration likely below 1% until after 2032.

Read sourceLi Auto says solid-state batteries could reach small-batch production by 2027 or 2028
According to a report by IT之家 citing Caixin, an internal source from Li Auto (LI) revealed that the company's solid-state batteries could achieve small-batch production capability by 2027 or 2028. Li Auto's senior director of power batteries, Liu Zhimin, stated that the company has multiple solid-state battery projects under development and has already completed prototype validation in eyewear products. However, he noted that achieving mature mass production in vehicles while ensuring user experience certainty will take approximately five more years. Liu highlighted ongoing challenges in simultaneously meeting lifespan, charging performance, and cost requirements for solid-state batteries. Separately, on September 7, Li Auto officially announced a new battery strategy, deploying self-developed batteries across its entire model lineup. The company confirmed that its self-developed batteries have already been integrated into mass production vehicles, including the Li L6, L8, and i8 models, with plans to fully transition all new and refreshed models to self-developed batteries.
