Huawei, the Guangdong-based Chinese tech company, has claimed to develop a new solid-state electric vehicle (EV) battery offering a driving range of over 3,000 km on a single charge and full charging capability in just 5 minutes.
Kabul 24: The patent reveals that the battery uses a nitrogen-doped sulfide electrolyte, boosting energy density to 400–500 Wh/kg—two to three times higher than current lithium-ion batteries. The ultra-fast charging enables a 0-100% charge in 5 minutes.
The main hurdles in commercializing solid-state batteries are stabilizing the lithium interface and reducing harmful side reactions, both of which the patent claims can be addressed through nitrogen doping of sulfide electrolytes.
However, industry experts note that while these claims are impressive in theory, real-world mass production is unlikely due to high production costs. Sulfide electrolytes are expensive, costing around $1,400 per kWh (approximately ₹1.2 lakh). Additionally, inadequate infrastructure for ultra-fast charging rates poses a significant challenge.
Huawei is not currently in the business of manufacturing power batteries, but its recent heavy investments in battery research and materials suggest ambitions to become a major player.
The claimed 3,000+ km range is based on the CLTC (China Light-Duty Vehicle Test Cycle), but under the EPA cycle, it would be around 2,000+ km—still far exceeding current mainstream EVs.Leading global battery manufacturers like Toyota, Samsung SDI, and CATL aim to commercialize solid-state batteries by 2027–2030. Huawei’s claims, if realized, could revolutionize the EV industry by eliminating range anxiety and charging delays, promising a brighter future for electric vehicles.
