CATL accelerates development of next-generation solid-state EV batteries
New reports confirm CATL has entered the trial production phase for its new solid-state batteries.
Solid-state batteries offer several advantages over conventional lithium-ion batteries. They promise higher energy density, improved safety, and faster charging times. They could mean longer driving ranges, reduced charging times, and even enhanced performance for electric cars.
CATL's all-solid-state battery technology can apparently deliver an energy density of up to 500 Wh/kg, a serious improvement over current lithium-ion batteries, which typically have an energy density of around 300-350 Wh/kg.
While the technology is still in its early stages, CATL's progress has been impressive. The company has reportedly produced 20 Ah (18 kWh at 800V) sample cells and is now focusing on refining the manufacturing process.
Despite the promising advancements, there are still plenty of challenges remaining. The latest reports suggest that charging speed and cycle life, which refers to the number of times a battery can be charged and discharged before its performance degrades, still need improvement. CATL is confident it can overcome these hurdles and bring all-solid-state batteries to market in the near future. CATL's chief scientist, Wu Kai, previously announced the company's aim to produce all-solid-state EV batteries in small volumes by 2027.
CATL is not alone in its pursuit of solid-state batteries. Toyota, Mercedes-Benz, and Stellantis are also investing heavily in this promising technology. Nio seems to be ahead of the competition, and the Chinese Penghui Energy achieved a mass-production breakthrough. GWM has already produced sample pouch cells, and QuantumScape is in the advanced development stages as well. The race is truly on to bring solid-state batteries to the mass market.
Advancements in solid-state battery technology could have a profound impact on the future of electric vehicles. With its dominance in the global EV battery market, once the technology reaches mass-production levels, we can expect a very quick roll-out across many markets. Initially, the technology will be expensive, but within a few years, the costs will drop to the current lithium-ion battery levels and at that point range anxiety will truly become a thing of the past.
