China Trials High-Density Solid-State EV Batteries, Claiming 1,500 km Per Charge
China’s Changan and GAC are planning 2026 road trials of solid-state batteries in electric cars, with Changan claiming 400 Wh/kg energy density and up to 1,500 km per charge, and GAC aiming to deploy the tech in its Hyptec SUV by year’s end. The move is part of broader work on solid-state chemistries—including sodium-based Naxtra variants—promising higher energy density, safer non-liquid electrolytes, and faster charging (potentially around 12 minutes 0-80%). While solid-state tech eyes quicker adoption, Li-ion batteries are expected to persist during the transition, with researchers reporting even higher densities in some lab-developed chemistries.,
