Tailan Energy announces highest energy density battery, of 720 Wh/kg

Part of the Tailan science includes a "lithium-rich manganese-based material" in the cathode, along with a wide, thin lithium composite anode. A proprietary, high-performance electrolyte also boosts its capabilities. "It has comprehensively improved the … performance of the battery and is expected to fundamentally solve the problems of battery life and safety anxiety of traditional lithium-ion batteries," the Tailan press release states. Tailan was founded in 2018. Its "latest deal amount" was worth $13.9 million, according to data collector PitchBook. They list this on their page: Researcher and developer of emerging energy technology focus on new solid-state lithium batteries and key lithium battery materials. The company develops technology of electronic special materials and resource recycling, enabling users with battery sales, battery leasing, graphite and carbon products sales and other services.

According to Tailan, those breakthroughs pertain specifically to ultra-thin and dense composite oxide solid electrolytes, high-capacity advanced positive and negative electrode materials, and an integrated molding process that culminates into an impressive 120 Ah solid-state lithium metal cell. Based on its specs, Tailan New Energy states its solid-state battery cell sets industry records in both energy density and storage capacity. In what Talian is calling a “world’s first,” the prototype cells house an energy density of 720 Wh/kg – more than double other cells currently being integrated into passenger EVs in China, like WeLion’s batteries for NIO, for example. Those 360 Wh/kg WeLion cells are expected to propel NIO EVs over 1,000km (620 miles) on a single charge later this year, so the potential of Talian New Energy’s technology to double that density in a similarly sized architectural footprint could reshape the mobility landscape. Breaking down its new prototype cell, the battery developer shared its potentially record-setting numbers stem from high-gram capacity, lithium-rich manganese-based material in the positive electrode, an ultra-wide and thin lithium composite in the negative electrode enabling high cycle stability, and a proprietary high-performance oxide composite solid-state electrolyte, which it says addresses the solid-solid interface impedance problem plaguing current solid-state lithium cells. The release goes on: Tailan New Energy improves the migration ability of charged particles inside the cathode by building an efficient ion and electron transmission network, and uses self-developed interface flexible layer materials to effectively reduce the interface impedance while also improving the interface stability, achieving It has comprehensively improved the comprehensive performance of the battery and is expected to fundamentally solve the problems of battery life and safety anxiety of traditional lithium-ion batteries. Tailan did not mention any specific plans for passenger vehicle integration yet, but did state its latest generation of all-solid-state battery cells are vehicle grade. If the company is able to scale this technology large enough for consumer vehicles while keeping prices down, it could easily double the range of the farthest-driving EVs on the road today.
