China''s tech giant claims 1,800-mile range for solid
Huawei has filed a patent detailing a sulfide-based solid-state battery design with energy densities between 180 and 225 Wh/lb, roughly
Assuming a similar efficiency, Huawei's battery should have more than three times the capacity of Lucid Air's pack to achieve the range claim for an EV. That is, about 350 kWh, which at 500 Wh/kg (let's pretend this energy density is achievable at pack level), should weigh more than 1,500 lb (700 kg).
Solid-state battery efforts might gain a significant boost from technology giant Huawei. The company patented a solid-state battery with an energy density between 400 Wh/kg and 500 Wh/kg. The battery uses a sulfide-based electrolyte and a lithium-metal anode, promising better ionic conductivity compared to other solid-state battery cells.
Huawei's energy storage technologies extend battery life, ensure safe operation and simplify maintenance and servicing (O&M) through precise management of battery cells, packs and racks, accurate control of charging and discharging, and innovative Smart String ESS technology.
US survey reveals a messy mystery Huawei has filed a patent detailing a sulfide-based solid-state battery design with energy densities between 180 and 225 Wh/lb, roughly two to three times higher than today's typical electric vehicle batteries.
