GAC develops new motor and battery technologies to increase EV range

Chinese automaker GAC, in collaboration with the Chinese Academy of Sciences, has developed a new electric motor technology using ultra-thin amorphous metal ribbons. These ribbons, measuring just 0.025 millimeters, lack a regular crystal lattice, which reduces energy loss from heat by 50 percent. This efficiency boost could potentially increase electric vehicle range by 30 to 50 kilometers without increasing battery weight.

In a separate technological advancement, GAC has moved its solid-state battery research into pilot production. The company reports that these batteries have achieved an energy density exceeding 400 Wh/kg, which could theoretically allow vehicles to exceed 1,000 kilometers of range on a single charge. The technology is expected to debut first in models from Hyper, GAC’s premium brand. Unlike conventional batteries that use liquid electrolytes, this solid-state approach uses solid materials to allow for more compact cells and improved safety.
