Lithium-ion batteries were first used in pacemakers. The self-discharge rate of the lithium-ion battery is extremely low, and the discharge voltage is gentle, so that the pacemaker implanted in the human body can operate for a long time without recharging. Lithium batteries generally have a nominal voltage higher than 3.0 volts, making them more suitable for use as integrated circuit power supplies. Manganese dioxide batteries are widely used in calculators, digital cameras, and watches. In order to develop more excellent varieties, various materials have been studied to create an unprecedented product.
　　 In 1992, the polymer lithium ion battery was successfully developed. Its practicality has greatly reduced the weight and volume of portable electronic devices such as mobile phones, notebooks, and calculators. Batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Polymer lithium-ion batteries do not contain metallic lithium and are rechargeable. The fifth-generation polymer lithium-ion battery of rechargeable batteries was born in 1996, and its safety, specific capacity, self-discharge rate and performance price ratio are better than lithium-ion batteries. Due to its own high technical requirements, only a few companies in the country are producing such lithium metal batteries.
　　 It can realize ultra-high-speed charging of the battery, and it is expected to greatly extend the life of the lithium battery. The first charge and discharge, if the time is longer (usually 3--4 hours is enough), the electrode can reach the highest oxidation state as much as possible ( Fully charged), when discharged (or used), it is forcibly placed to the derated voltage, or until it is automatically turned off, such as to activate the battery usage capacity.
　　 Turning back to the 18650 lithium battery, this "old" battery, which is often attacked by various cottage mobile power manufacturers, is still widely used in various electronic devices, such as mobile power. In fact, in high-end applications, such as professional imaging equipment, laptop batteries, 18650 has been the main role, the large-scale application of Tesla electric vehicles has improved the high security image of this battery. The 18650 lithium battery has mature technology, good consistency and high capacity density. It has the advantage that polymer square batteries cannot be replaced in large-capacity hybrid applications.
