Geely's New Ultra Short Blade Battery Takes On 1,100 kW Charging While Fighting Degradation

Chinese automakers keep pushing charging power into territory Western brands have yet to reach. At a launch event in Ningbo, Geely Auto Group unveiled a charging setup capable of delivering 2.2 megawatts from a single gun, with some of its premium models peaking near 1,100 kW. Geely claims it is the first company whose station can supply megawatt-level charging to two vehicles at once. For comparison, the quickest-charging EVs sold in the United States top out around 400 kW, and a 10-80% stop for most mainstream models still takes roughly half an hour.

Speed at that level puts serious stress on a battery, and Geely’s leadership did not pretend otherwise. CEO Jerry Gan said the company does not pursue fast charging at the cost of pack life, warning that a frequently quick-charged battery can suffer irreversible decline if it is never maintained. Geely’s answer is the Ultra Short Blade Battery, demonstrated in a Lynk & Co 10 that went from 10% to 97% in 8 minutes and 40 seconds. To back up its confidence, Geely extended the pack’s warranty from eight years/150,000 km to eight years/200,000 km.

According to chief engineering scientist Ren Xiangfei, degradation comes down to lithium plating and heat. Geely tackled both by shortening the cells to 395 mm and 370 mm, cutting the distance ions must travel and lowering internal resistance. The cathode uses high-entropy elements to widen ion pathways, while the graphite anode was restructured to keep ions from piling up. A “lithium pulse restoration” routine injects micro-amplitude pulses to clear surface accumulation, and an AI system called Xingrui PowerMind forecasts battery temperatures 30 seconds ahead, adjusting charging in real time. Liquid cooling spans five points, from the storage battery to the charging port, holding average cell temperature near 55°C with a 65°C ceiling.

Plenty remains unproven. Megawatt charging only began scaling in China last year, so long-term durability data is years away, and rival BYD drew scrutiny this spring after a blogger reported temperatures above what a test vehicle displayed. Degradation also depends heavily on driving style, climate and charging habits, and Western research offers mixed conclusions on frequent fast charging. Still, Geely’s longer warranty suggests the company believes its engineering holds up.
