Lithium battery characteristics and usage analysis

High energy density: depending on the electrode material, it can reach 150～200Wh/kg (540～720kJ/kg) by mass; it can reach 250～530Wh/L (0.9～1.9kJ/cm3) by volume. [2] The open circuit voltage is high: it varies with the electrode material and can reach 3.3 to 4.2V. Large output power: It varies with different electrode materials, up to 300～1500W/kg (@20sec). [1] [Inconsistent with source] No memory effect: Lithium iron phosphate battery has no memory effect. The battery can be charged and discharged at any time without emptying the battery, and it is easy to use and maintain. Low self-discharge: <5%～10%/month. Due to the built-in monitoring circuit of the smart lithium battery, the working current of this monitoring circuit is even higher than the self-discharge current. Wide operating temperature range: it can work normally between -20℃～60℃. The charging and discharging speed is fast. Therefore, lithium batteries are widely used in consumer electronics, military products, and aviation products. The use of lithium batteries ●The use of portable electrical appliances At present, mobile phones, notebook computers, micro-cameras and other electrical appliances that require portable power sources have become an indispensable part of people’s lives. In terms of their power sources, lithium batteries are selected without exception. The mainstream of the market. ●Use in the transportation industry With the advancement of social civilization, people's awareness of environmental protection has increased and environmental requirements have increased, and environmentally friendly transportation has entered people's field of vision. At present, my country's electric light vehicles, mainly electric bicycles, are showing a trend of vigorous development. Lithium batteries have begun to be used in some high-end vehicles. In terms of electric vehicle development, lithium batteries have become the mainstream. ●Use in military equipment and aerospace industry. In military equipment, lithium batteries are mainly used as power starting power sources, wireless communication radio power sources, micro-unmanned reconnaissance aircraft power lithium-ion batteries, etc., in addition, such as laser sights, night Nowadays, lithium batteries are commonly used in video cameras and pilot life-saving radio power supplies. ●Lithium batteries have been used in geosynchronous orbit satellites and low-orbit communication satellites as the power for launch and in-flight calibration and ground operations. ●Lithium battery energy storage technology is used in all aspects of power generation, transmission, distribution, and use, and its applicable scale is less than 100MW. There are currently 482 projects in operation worldwide. The total energy storage scale reaches 1405MW. The rapid development of the energy storage market in the United States, Europe, and Japan uses multiple revenues (peak shaving, frequency modulation, user-side revenue, etc.) to overlap the market with huge space.
