Energy density exceeds 400wh/kg, usable at -40℃! GAC Haobo releases all-solid-state battery

On April 12, GAC held a press conference today and officially announced that it has completed the research and development of 30Ah large-capacity all-solid-state battery cells, which will be first used in the Haobo model, with the time node being 2026.

It is reported that the battery uses 100% solid electrolyte, has the characteristics of ultra-high energy density, super intrinsic safety (mainly referring to monomer safety), ultra-wide operating temperature range (-40-100°C), and has "moved from the laboratory to mass production application."

Li Jin, head of GAC Aion's battery R&D department, said that all-solid-state batteries have higher energy density, higher intrinsic safety, and a wider temperature range. He said the difficulty of developing all-solid-state batteries is comparable to climbing Mount Everest, and requires breakthroughs in materials, design, manufacturing, and integration.

Officials said that with the third-generation sponge silicon negative electrode and high-area capacity solid-state positive electrode technology, the energy density of the all-solid-state battery has reached more than 400Wh/kg.

Compared with the current mass-produced liquid lithium-ion batteries, the volume energy density is increased by more than 52%, and the mass energy density is increased by more than 50%. It can easily achieve a range of over 1,000 kilometers. In terms of safety, it can be punctured or cut without failure, and can withstand a 200-degree hot box.
