Lithium Cobalt Oxide Battery is a type of lithium-ion battery that uses lithium cobalt oxide (LiCoO2) as the cathode material. This kind of battery is characterized by high energy density, long cycle life and low self-discharge rate, so it is widely used in portable electronic devices, power tools and other fields.

The lithium-cobalt oxide battery has a high operating voltage, usually between 3.6V and 4.2V, which enables it to provide a higher energy output. It also has a relatively long cycle life and is able to maintain stable performance after multiple charge/discharge cycles. In addition, lithium cobalt oxide batteries have a low self-discharge rate, which enables them to maintain a high level of charge when not in use for extended periods of time.

However, lithium-cobalt oxide batteries also have some drawbacks, such as high sensitivity to overcharge and overdischarge, and need to be equipped with complex battery management systems to ensure their safe use. Nevertheless, lithium-cobalt oxide batteries are still attracting attention for their excellent performance and wide range of applications.
