Hyper Unveils Pioneering Solid-State Battery Aiming for Mass Production by 2026

On April 12, 2024, Chinese automaker Hyper, a subsidiary of GAC Aion, revealed the creation of its new solid-state EV battery, marking a watershed moment in the electric vehicle (EV) market.

Hyper's solid-state battery has a 100% solid-state electrolyte, resulting in a considerable boost in energy density. This enhancement allows more power to be put into the same physical space, which is a significant benefit in the EV business, where efficiency and compactness are critical. The battery's improved safety features and ability to survive a broader range of temperatures have important consequences for the performance and dependability of EVs.

The game-changing battery employs third-generation sponge silicon anodes and high-capacity solid-state cathode technologies. This combination results in an impressive energy density of more than 400 Wh/kg. This offers a 52% improvement in volume energy density over conventional lithium-ion batteries, as well as a more than 50% increase in mass energy density. This innovation results in an incredible driving range of more than 1000 kilometres on a single charge.

Furthermore, the battery provides remarkable safety performance, withstanding punctures and cutting without fail and tolerating temperatures of up to 200 degrees Celsius.

Hyper's advancements in solid-state battery technology put GAC Aion in a position to begin putting the batteries into production vehicles by 2026.
