Li Auto introduced Lianshan, an in-house electric-powertrain platform, at its Power Day event in China on October 20. It brings together batteries, electric-drive units and the company’s charging network. The launch accompanies Li Auto’s shift from CATL-supplied batteries toward packs developed through its joint venture with Sunwoda, formed in 2025. The company has also said it plans to invest 2.65 billion yuan ($394 million) in Sunwoda’s EV battery subsidiary for an 8.79% stake.
Li Auto outlined two conditional lifetime protections: a replacement vehicle of the same specification if a battery quality defect causes a fire that leads to the vehicle being scrapped, and payment of the difference between insurance coverage and the actual payout if a collision or chassis scrape triggers a battery fire and the vehicle is written off. The company says batteries will retain at least 75% capacity for eight years or 160,000 kilometers. It also cited tests involving a 500-joule underside impact, 48 hours submerged in one meter of water, and resistance to fire for 24 hours after a cell enters thermal runaway.
Under the CLTC test cycle, Li Auto quoted 430 kilometers of electric range for the new L8 and 780 kilometers for the 2026 i6, improvements of more than 8% over their 2025 counterparts. The company says its electric-drive components add range through a redesigned rotor material and power module. Its charging network has passed 4,200 stations, with 5C equipment at all highway locations. The 2026 i6, featuring an in-house 5C battery, is due to launch on October 28, with deliveries expected in early November.
