In 2026, the center of gravity in the electric-vehicle battery contest is moving down from vehicle specs to cell chemistry. Liquid lithium-ion—ternary and lithium iron phosphate (LFP)—still accounts for over 99% of China’s installed battery capacity, but sodium-ion, semi-solid, all-solid-state, LMFP

Industry repair logs and cell-test data show the real cause of premature e-bike, e-scooter and low-speed EV battery failure is rarely nominal capacity loss—it is internal resistance (IR) silently doubling. On Google Trends through 2026, “ebike battery”, “electric scooter”, “lead acid battery” and “l
