China seems to be leading the way in battery development, with recent announcements of increased energy density solid-state batteries, and batteries that can last for close to a million miles of service. The two companies are reporting batteries already in service or close to being released to the public. Tailan New Energy Doubles Down Reporting in Electrek, Scooter Doll reports Tailan New Energy has announced vehicle-grade all-solid-state lithium batteries with energy density “twice that of other cells in the segment.” Only six years old, the firm has taken a leading role in the battery industry. The Energy Viking reports further. Tailan has achieved a 120 Amp-hour solid-state battery cell using “ultra-thin and dense composite oxide solid electrolytes, high-capacity advanced positive and negative electrode materials, and an integrated molding process.” Housing an energy density of 720 Watt-hours per kilogram, twice that of other batteries installed in passenger electric vehicles in China, these new cells could effectively double the mileage per charge. …
