The application of lithium cobalt oxide battery is still relatively small. The technology of cobalt lithium for small batteries is very mature, but the cost of cobalt lithium is too high. Many companies use manganese lithium instead, and some are manganese lithium. Lithium cobalt oxide battery has stable performance. Currently, the technology used in mobile phones is the most mature, but the biggest disadvantage of application is high cost. Cobalt is a scarce strategic metal. In addition, it is also difficult to apply to power batteries.
