Li Auto announces: battery spontaneous combustion and scrapping compensated with a new car! Confident after 6 years of in-house development

What happened: Li Auto unveiled its Liantian electric technology system at Power Day, covering in-house 5C battery cells, electric drive, silicon carbide power chips and its supercharging network, plus lifetime guarantees for battery fire and scrapping cases. Key numbers: 5C LFP cell energy density 2.6% higher than 2C; winter peak power up over 40%; Why it matters: Li Auto says in-house development gives it full manufacturing and usage data for quality control, while it continues buying from suppliers. Executive Ma Donghui said in-house battery costs are not necessarily lower than sourcing.
