At today’s 2024 GAC Technology Day, GAC launched all-solid-state battery technology, which is expected to be installed on Hyper models in 2026.
Li Jin, head of the GAC Aion Battery R&D Department, said that all-solid-state batteries have higher energy density, higher intrinsic safety, and a wider temperature range. He said that the development of all-solid-state batteries is as difficult as climbing “Mount Everest” and requires breakthroughs in materials, design, manufacturing, integration and other aspects.
According to reports, the battery uses 100% solid electrolyte and has the characteristics of ultra-high energy density, ultra-strong intrinsic safety (mainly referring to monomer safety), ultra-wide operating temperature range, and has “moved from the laboratory to mass production applications.”
This battery relies on the third-generation sponge silicon anode and high-area capacity solid-state cathode technology to achieve an all-solid-state battery energy density of more than 400 Wh/kg. Compared with current mass-produced liquid lithium-ion batteries, the volume energy density is increased by more than 52%, and the mass energy The density is increased by more than 50% and can achieve a battery life of more than 1,000 kilometers; in terms of safety, it can achieve acupuncture and cutting without failure, and can withstand 200-degree hot boxes.
According to previous reports, at the 21st Guangzhou International Auto Show in November last year, GAC Group announced that it would implement all-solid-state batteries in vehicles in 2026. Then in early February this year, GAC Aion Hyper solid-state battery revealed the latest progress in research and development – the energy density exceeds 350Wh/kg. Same weight, 3 times the power.
GAC Aion Laboratory announced last year that it had completed the experimental verification of the interface modification technology of solid-state batteries and announced a new technological breakthrough. This technology will reduce the life decay of solid-state batteries by 50% and maintain battery capacity above 90% after 150 cycles.
