Lithium-metal batteries are a type of rechargeable battery that uses lithium metal as the anode. Unlike traditional lithium-ion batteries that use a lithium-ion intercalation compound, lithium-metal batteries offer the potential for higher energy density due to the high theoretical capacity of lithium metal. In these batteries, lithium ions move from the anode to the cathode during discharge and back during charging. This technology is noted for its lightweight properties and increased energy storage capability, making it attractive for various applications, including electric vehicles and portable electronics. However, lithium-metal batteries also face challenges such as dendrite formation, which can lead to short circuits and safety issues. Ongoing research aims to improve their safety and efficiency for widespread use.
PowerCo, a subsidiary of Volkswagen Group, and battery technology company QuantumScape have recently joined forces to spearhead the production of next-generation solid-state lithium-metal batteries. This partnership marks a significant advancement…
