Lithium-ion battery is a lithium metal or lithium alloy anode materials, the use of a battery of electrolyte solution and lithium-ion batteries and rechargeable batteries with lithium ion polymer battery is not the same. Thomas Edison, inventor of the lithium-ion battery is. Very lively due to the chemical properties of lithium metal, lithium metal processing, preservation, use, environmental requirements are very high. Therefore, lithium-ion battery has not been used. As the end of 20th century the development of microelectronics, miniaturization of devices increasing, very high demands on the power supply. Lithium battery into the scale of the practical stage.
