In less than six months since their initial application to incorporate semi-solid-state batteries into three of their EV models, Nio Inc. (NYSE:NIO) has followed up with a second filing.
According to reports from CnEVPost, NIO has formally lodged a second request with China's Ministry of Industry and Information Technology (MIIT) to incorporate solid-state batteries.
While this latest filing does not introduce any new vehicle models, it does contain updates to the specifications of 11 more EVs, now including comprehensive information about the cutting-edge battery technology.
NIO currently only sells eight models, suggesting that the battery upgrades will not be limited to existing models, but future EVs as well.
The filing included nine SUVs and two sedans, and the specifications for these vehicles now incorporate the utilization of battery cells sourced from Huzhou WeLion Technology Co. The battery assemblies, based on the cells, are produced by a subsidiary of NIO in Nanjing.
While the details may not explicitly refer to solid-state batteries, it is worth noting that WeLion Huzhou operates as a fully owned subsidiary of Beijing WeLion New Energy Technology, which is NIO's supplier for semisolid-state batteries.
NIO introduced the 150-kWh semi-solid-state battery during the unveiling of its flagship sedan, the Nio ET7, at the Nio Day 2020 event held on January 9, 2021. However, deliveries for this technology have yet to begin.
Shares of NIO are down 0.84% in mid-day trading on Monday.
