China's first all-solid-state battery cell meeting new national standard begins production

(China Daily) China's first all-solid-state battery cell meeting the newly released national standard for solid-state batteries officially rolled off the production line on Tuesday in Guangzhou, the capital of Guangdong province.  

It became the first all-solid-state battery in the country to pass authoritative testing by China Automotive Battery Research Institute Co and commence mass production following the introduction of the new national standard in August.  

With controllable costs, the energy density of the all-solid-state battery cells ranges from 260 to 480 Wh/kg. Its cycle life is comparable to conventional batteries, and it supports stable fast charging. It was developed by Guangzhou Greater Bay Technology Co.  

At a ceremony marking its mass production on Tuesday, the company signed strategic cooperation agreements with several companies to commercialize all-solid-state batteries in high-end electric motorcycles, the low-altitude economy, computing power centers, and high-end energy storage scenarios.  

The company is based in Guangzhou's Nansha district, which has become a hub for battery storage companies and leading vehicle and intelligent network companies.

"The hub helps create a complete industrial ecosystem of batteries, energy storage, new energy vehicles, and intelligent networking, providing essential soil and nutrients for this national breakthrough," said Pei Feng, co-founder and president of Guangzhou Greater Bay Technology Co.  

By 2030, the global demand for power batteries will reach 3 TWh, with China capturing 70 percent of the market share. At the same time, all-solid-state batteries are expected to exceed 100 GWh by 2030, according to Pei.  

Most solid-state batteries in China are still at the laboratory sample stage, according to Dong Yang, chairman of the China Automotive Battery Innovation Alliance.  

Leveraging the high compatibility of deep eutectic-based composite solid electrolytes with existing mature lithium battery production lines, the company transitioned from liquid to all-solid-state battery manufacturing after conducting targeted modifications and process optimizations on a 4 GWh production line.  

"Deep eutectic-based composite solid electrolyte represents a unique technological path. It will inspire the entire battery sector to more actively engage in research and application in this area," said Dong.
