CATL Expands All-Solid-State Battery Effort: 1,000-Plus Team, 500 Wh/kg 20Ah Samples

Contemporary Amperex Technology (CATL) has expanded its all-solid-state battery effort, with its dedicated research team now exceeding 1,000 people and 20 ampere-hour samples entering trial production at an energy density of about 500 Wh/kg, LatePost and industry media reported in early November. CATL is focusing on the sulfide route, which promises a roughly 40% gain over existing cells, though charging speed and cycle life remain below target. Company technical leaders caution that full commercial maturity is still about five years away and that much of the sector's solid-state hype overstates near-term viability. The progress highlights China's push to secure next-generation battery leadership even as current lithium-iron-phosphate and ternary cells dominate today's EV market.
