BYD’s commitment to LFP batteries stems from their safety advantages and cost-effective supply chain.
On November 7, at the 2025 Japan Mobility Show, Li Yunfei, General Manager of BYD Brand & PR, reiterated that BYD will continue to pursue the safety-focused lithium iron phosphate (LFP) battery technology route.
He noted that China’s power battery industry has developed rapidly and matured technologically, and LFP batteries can meet daily usage needs under existing charging infrastructure, with winter insulation technology increasingly optimized. Li emphasized, “Safety is the most fundamental, and the greatest form of luxury.”
BYD’s insistence on LFP is driven by multiple factors. First is safety. LFP materials have high thermal stability; while ternary lithium can catch fire in nail penetration tests, BYD’s Blade Battery achieves “no smoke, no fire,” supported by data from millions of installed vehicles with zero spontaneous combustion incidents.
Second is cost and supply chain advantage. LFP does not rely on expensive metals such as cobalt or nickel. In 2025, its average price is around 380 yuan/kWh ($53.20/kWh), compared with 550 yuan/kWh ($77.00/kWh) for ternary lithium. In addition, domestic reserves of phosphorus and iron are abundant, making the supply less vulnerable to external constraints.
Previously, LFP’s main limitation was lower energy density and limited range. However, BYD’s Blade Battery design significantly improves space utilization by about 50%, enabling ranges over 600 km, with the second-generation product exceeding 1,000 km.
Li noted that public perception of EV battery safety is often influenced by news events, but most consumers do not focus on battery chemistry. He stressed that all current and future BYD models will continue to adopt the LFP route.
He also reviewed the history of China’s electric buses. Since 2010, electric buses have been operating in numerous cities and routes for 15 years, without major fire incidents—a success closely tied to the use of LFP batteries.
Regarding solid-state and alternative battery technologies, Li previously stated that BYD, as both a vehicle and battery manufacturer, continues research and design to maintain technological reserves and market competitiveness.
Data shows that from January to September this year, LFP battery installations reached 493.9 GWh, up 42.5% year-on-year, with a market share exceeding 80%, making LFP the mainstream choice for EV power batteries.
