　　A proposal submitted by China to develop the first international standard for solid-state batteries used in electric vehicles has been approved by the International Electrotechnical Commission, amid growing efforts by Chinese automakers and battery producers to advance vehicle validation and pilot production.

　　The State Administration for Market Regulation said earlier this month that the project would cover guidance on applications, test items and test conditions for solid-state lithium-ion cells used to power electric road vehicles.

　　China will lead the drafting, with experts from France, South Korea and Japan participating, according to the SAMR.

　　The SAMR said the proposed standard would give automakers around the world a common reference for developing and producing solid-state batteries.

　　Ji Xuehong, director of the Automotive Industry Innovation Research Center at North China University of Technology, said the industry was pursuing multiple technical routes and lacked consistent terminology, testing standards and methods. A common framework could help avoid unnecessary duplication and the inefficient use of resources.

　　Yang Weibin, an expert on new energy vehicles and power batteries, said the standard, once finalized, will also lower the costs associated with technical coordination and product validation for Chinese companies entering overseas markets.
