Lithium metal batteries are a type of electrochemical cell that utilizes lithium metal as the anode material. They are known for their high energy density and the ability to deliver a significant voltage output. This type of battery is distinct from lithium-ion batteries, which use lithium compounds for the anode and can be recharged, whereas lithium metal batteries are typically non-rechargeable. They are characterized by their lightweight nature and are commonly used in applications that require long-lasting power in a compact design, such as in certain electronics, military devices, and medical equipment. However, they are associated with safety concerns, especially regarding dendrite formation, which can lead to short circuits and battery failure. Research is ongoing to improve their safety and efficiency for broader use in consumer electronics and electric vehicles.
