- Ganfeng Lithium began small‑scale production of a 10 Ah lithium‑metal solid‑state battery with a 500 Wh/kg energy density.
- Ganfeng Lithium supplies lithium‑hydroxide and other EV battery materials to OEMs including Tesla, Hyundai, BMW, Volkswagen and Chinese automakers.
- Ganfeng Lithium developed a “zero‑strain” lithium‑alloy anode that expands only 3‑5% during charge‑discharge and survives nail‑penetration and heating tests up to 250 °C.
- Ganfeng Lithium’s silicon‑based solid‑state cells achieve 400 Wh/kg energy density and have demonstrated more than 1,100 cycles, positioning them for large‑scale production.
- FAW Group installed a lithium‑rich manganese semi‑solid‑state EV battery delivering 500 Wh/kg, a 142 kWh pack and over 1,000 km (620 mi) CLTC range.
Why it matters: Automakers gain a battery that can boost range and cut weight, while Ganfeng secures high‑value contracts with Tesla and others, accelerating China’s lead in high‑energy solid‑state EV power.
