Lithium batteries are a type of rechargeable battery commonly used in electronic devices such as smartphones, laptops, and electric vehicles. They are known for their high energy density, long lifespan, and fast charging capabilities. Lithium batteries use lithium ions to transfer energy between the positive and negative electrodes, allowing for efficient energy storage and release. Research in this area focuses on improving battery performance, increasing energy density, and developing new materials and technologies to enhance the safety and durability of lithium batteries. Additionally, researchers are working on ways to recycle and reuse lithium batteries to reduce their environmental impact.
