GAC Aian reveals a new breakthrough in solid-state batteries: life decay reduced by 50%

November 22 news, recently, solid-state battery technology has once again attracted widespread attention and is regarded as the most potential solution for the next generation of power batteries. its over 400 The extremely high energy density of Wh/Kg, excellent safety against high temperature and puncture resistance, and wide temperature range operating window make it the ultimate choice for power batteries.

At a press conference held by GAC Group on November 17, GAC Aian announced that it will achieve full mass production of cars equipped with all-solid-state batteries in 2026. For the first time, The first model to use this technology will be Haopin.

According to the editor’s understanding, in just the past three days, GAC Aion Laboratory has made important technological breakthroughs. They announced the successful completion of experimental verification of interface modification technology for solid-state batteries and announced innovations that were different from the past. The introduction of this technology will reduce the life decay of solid-state batteries by 50%. After 150 weeks of cycle testing, the battery capacity can still remain above 90%.

Solid-state batteries have problems with high contact resistance and poor stability due to their solid-solid contact interface characteristics, resulting in rapid battery capacity attenuation and shortened battery life. Through the special design of solid electrolyte components, GAC Aion Laboratory successfully induced the formation of an interface buffer layer, effectively reducing the interface impedance and improving the stability of the interface.

In experimental tests, the capacity retention rate of solid-state batteries using interface modification technology was significantly improved, exceeding 90%, after 150 cycles compared to conventional solid-state batteries. The battery life degradation rate is reduced by 50%.

In addition, GAC Aian Laboratory is also accelerating the development of new solid-state electrolytes, solid-solid interface modification and other related technologies to further optimize the comprehensive performance of solid-state batteries. In addition to applications in the automotive industry, the dramatic improvement in the performance and weight of solid-state batteries will also bring major breakthroughs to fields such as the drone industry, robotics industry, mechanical exoskeletons, and medical technology that have high lightweight requirements for batteries.

The above is the detailed content of GAC Aian reveals a new breakthrough in solid-state batteries: life decay reduced by 50%. For more information, please follow other related articles on the PHP Chinese website!
