Do you know what types lithium battery?

Source: 2020 - 04 - 04 now hits: lithium battery type 1 a, according to the anode, cathode material classification. Lithium cobalt oxide battery: the ratio can make the lithium cobalt oxide as a mobile phone. Due to the molecular structure of the chemical elements of cobalt acid lithium stability is good, so better than high capacity battery structure, integrated performance is outstanding, but its poor safety, cost is very high, it is mainly used for medium and small type batteries, widely used in the small laptop computers, smart phones, MP3/4, laptop computers and digital cameras in small electronic devices, product performance is stable, charging and discharging power rating voltage is normal, comprehensive performance is outstanding, 3 standard voltage. 7 V，2. Manganese acid lithium battery: manganese acid lithium battery in a 20 - 30 a discharge current, and with the appropriate heat accumulation. Low cost, safety, and good low temperature performance of the anode material, but its material itself is not stable, easy to decompose to produce gas, mixed with other materials used, in order to reduce the cost of the battery, but the cycle life of attenuation is rapid, easy to expand, the high temperature performance is poorer, relatively short life, it is mainly used in large and medium-sized battery, power battery rated voltage of 3. 7 V。 Lithium manganese acid used in power tools and accessories, medical equipment, hybrid and new energy vehicle. 3. Rechargeable batteries, lithium iron phosphate lithium phosphate has good electrochemical safety performance and low resistance. High energy density, good if the lamination process, capacity is bigger, can achieve 185 wh/kg. Excellent safety performance, at the completion of the charge and discharge process, the structure of the battery will not produce very big change, a violent explosion will not happen, even if a short circuit and overcharge, collision accident, is still very safe. A, lithium battery internal structure of the general classification 1. Lithium battery: the lithium battery is usually a manganese dioxide anode materials, metal anode materials for lithium metal or its alloy steel nonaqueous electrolyte solution of rechargeable battery. 2. Lithium ion battery: the lithium ion battery usually in lithium alloy metal oxide anode material, graphite as the anode materials, nonaqueous electrolytes of rechargeable battery. Third, according to the classification of the first is a simple steel shell material rechargeable battery. Most manufacturers use steel for the battery shell material, because the physical stability of the steel materials, anti - Pressure is much higher than aluminum shell materials, each manufacturer in the design of the structure optimization, the safety device is placed in the battery core, steel battery shell column security has reached a new level in the second category, the rechargeable battery is made of aluminum. Aluminum shell rechargeable battery is a shell, a soft shell, as for the anode material, there are a lot of kinds, depending on which one do you like to use, the use of the third type of material or different, polymer lithium-ion batteries, the shell is a kind of polymer materials, mostly silvery white, a few manufacturer is grey black, the personage inside course of study is called black skin. Is mainly used in automotive electronic products, GPS tracking batteries, tire pressure detection, vehicle traveling data recorder) , share, bicycle, solar energy storage lamp, cryogenic interphone, etc
