18650 li ion rechargeable battery

　　Classification of 18650 li ion rechargeable battery

　　Classification of 18650 li ion rechargeable battery: (1) Solid polymer electrolyte lithium-ion batteries. The electrolyte solution is a compound of polymer and salt. This kind of battery has low ionic conductivity at room temperature and is suitable for high temperature use.

　　(2) Gel polymer electrolyte lithium ion battery. That is, preservatives such as viscosity additives are added to the solid polymer electrolyte solution to improve the ionic conductivity so that the rechargeable battery can be used at room temperature.

　　(3) Lithium-ion batteries with polymer cathode materials. Using conductive polymer as the cathode material, the energy density of ultra-low temperature lithium batteries is three times that of current lithium batteries. Because solid electrolytes are used instead of liquid electrolytes, compared with liquid lithium batteries, polymer lithium batteries have thin shapes, free total area, The sample is random and will not cause safety problems such as leakage, ignition and explosion. Therefore, aluminum-plastic composite film can be used to make the battery case to increase the specific capacity of the entire battery. Polymer lithium batteries can also use polymer materials as the positive material of the battery. The energy density of polymer lithium batteries is 50% higher than that of liquid lithium batteries. In addition, polymer lithium batteries have gradually improved compared to lithium batteries in terms of operating frequency and battery charging cycle life. Based on these advantages, 18650 li ion rechargeable battery are called the next generation of lithium-ion batteries.
