[New Standard for All-Solid-State Batteries Introduced to Address Issues Such as Vague Industry Definitions and Lack of Testing Methods] The China Society of Automotive Engineers (China-SAE) has officially released the group standard "Determination Method for All-Solid-State Batteries", which, for the first time, clarifies the definition of all-solid-state batteries, addresses issues such as vague industry definitions and lack of testing methods, and lays the foundation for technological upgrades and industrialisation applications. The new standard stipulates that for a battery to be classified as an "all-solid-state battery", ion transfer must be achieved exclusively through a solid electrolyte, establishing a strict technological demarcation from hybrid solid-liquid electrolyte batteries. The introduction of this new standard provides a unified benchmark for enterprise R&D, certification, and market applications, facilitating the optimization of material development and process design, reducing promotion costs, while also preventing the confusion caused by "pseudo all-solid-state" products and safeguarding the interests of consumers and industry order.
