With the development of scientific technology, lithium batteries have become the mainstream. Lithium batteries can be broadly classified into two types: lithium metal batteries and lithium ion batteries. Lithium ion batteries do not contain lithium in the metallic state and are rechargeable. The fifth generation of rechargeable batteries, lithium metal batteries, was born in 1996, and the safety, specific capacity, self-discharge rate and cost performance of rechargeable batteries were all superior to those of lithium ion batteries. Due to its own high technical requirement limits, only a few countries of companies are producing such lithium metal batteries. Lithium batteries were used in cardiac pacemakers in the earliest days. The lithium battery has the advantages of extremely low self-discharge rate, mild discharge voltage and the like, so that the pacemaker implanted into a human body can operate for a long time without recharging. Lithium batteries generally have a nominal voltage of greater than 3.0 volts and are more suitable as integrated circuit power supplies. Manganese dioxide batteries are widely used in calculators, digital cameras and watches. In order to develop a variety having more excellent properties, various materials have been studied to produce an unprecedented product. Sony succeeded in developing lithium ion batteries in 1992. Its practical application makes the weight and volume of portable electronic equipment such as mobile phone, notebook, calculator, etc. greatly reduced.
