Lithium is a metallic element. Its chemical symbol is Li (English name lithium). It is a silvery white, very soft and chemically active metal. It is the lightest of metals. Apart from being used in the atomic energy industry, it can make special alloys, special glass (fluorescent glass for TV sets) and lithium batteries. In lithium batteries, it is used as the anode of a battery.
The lithium battery has the advantages of stable discharge voltage, wide operating temperature range, low self discharge rate, long storage life, no memory effect and no pollution.
Lithium batteries are also divided into two categories: non rechargeable and rechargeable two. A rechargeable battery is called a disposable battery. It can only convert chemical energy into electricity at one time. It can not restore the energy to chemical energy (or restore poor performance). Rechargeable batteries are called "two" batteries (also known as batteries). It converts electrical energy into chemical energy and stores it. When it is used, it converts chemical energy into electrical energy. It is reversible, such as energy, chemical energy, and lithium batteries.
Smart portable electronic products require size and light weight, but the size and weight of a battery are often the largest and heaviest compared with other electronic components. For example, to the "big brother" is a "thick and heavy", and today's mobile phone is so light. Among them, battery improvement is important: in the past it was nickel cadmium battery, and now it is lithium ion battery.
