中国牵头的车用固态电池IEC国际标准提案获立项，但属于已传播的行业标准化进展

A Chinese-proposed international standard for automotive solid-state batteries has been approved as a new work item by the International Electrotechnical Commission (IEC) – marking the first of its kind for the advanced power systems and the nation’s latest effort to shape rules in emerging industries.
Led by China, with input from technical experts in France, Japan, South Korea and other countries, the proposal outlined application guidelines, items and conditions for testing rechargeable lithium-ion solid-state batteries used in electric vehicles (EVs), according to an official statement by the State Administration for Market Regulation (SAMR).
The governmental agency said the framework would draw on domestic research and development benchmarks to standardise testing specifications for solid-state batteries, which are widely viewed as the next frontier for EV power systems.
While EVs on the market today mostly run on liquid-electrolyte lithium-ion batteries, solid-state alternatives are only beginning to see early, limited commercialisation. Beyond cars, their enhanced stability and performance across extreme temperatures have positioned them as promising power sources for emerging sectors, including humanoid robots, drones and electric vertical take-off and landing aircraft.
Announced by the SAMR last week, the China-led proposal comes amid intensifying global competition in advanced technologies, as major economies increasingly leverage standard-setting to secure long-term industrial influence.
“When Chinese products go to an overseas market, they will more easily meet the requirements – there will be few major changes in parameters, production processes and so on,” said a veteran Chinese researcher on international standardisation, who spoke on condition of anonymity. This would place China in the position of setting benchmarks that others followed, she noted.
Both Europe and Japan have pursued similar strategies to secure early leadership in emerging technology standards, spanning domains from telecommunications to new materials, the researcher added. “Every country has clear strategic ambitions – no one is hiding it.”
China has accelerated its standards architecture in recent years alongside broader global interest in solid-state batteries. In July, the country enacted the world’s first national standard for automotive solid-state batteries using quantitative performance metrics to draw clear technical boundaries between all-solid-state, mixed solid-liquid and liquid batteries.
Separately, the Ministry of Industry and Information Technology released 10 draft industry standards for public comment last month.
Yang Chaoxing, a battery analyst at market intelligence provider Shanghai Metals Market, wrote in a research note on Monday that initiating an IEC-level framework signalled the industry had reached a “tipping point”. Standards were no longer optional as carmakers worldwide developed solid-state batteries, he added.
“That means China’s testing methods and evaluation systems could become the global default – and that’s worth more than how many batteries it sells,” Yang noted, adding that the rules could also help drive domestic industrial upgrading and accelerate market consolidation by weeding out outdated manufacturing capacity.
But while the standards could help establish testing protocols, complex manufacturing and financial hurdles remained, Yang added. “Standards are a catalyst for industrialisation, not a cure-all,” he warned.
