The Ministry of Industry and Information Technology launches the sodium battery working group for preliminary evaluation of puncture testing, further accelerating industrialization.

In recent years, as the industrialization process of sodium-ion batteries in our country has accelerated, the industry has developed rapidly. With battery safety standards continuously iterating and improving, puncture testing, as a core experiment simulating mechanical abuse and validating the internal short-circuit risk of battery cells, has become a key indicator for safety evaluation of power batteries. Currently, sodium-ion battery technology is being rapidly industrialized, with products continuously upgrading towards higher energy density and higher integration. To this end, the Ministry of Industry and Information Technology has officially launched a specialized evaluation for puncture testing of sodium-ion batteries, covering various energy density products for systematic safety verification, assisting companies in identifying safety hazards in advance, optimizing product design, and supporting the unified implementation of industry standards.
