Summary of the performance characteristics of polymer lithium ion battery

Source: 2020 - 03 - Hits: behold, 28 times of polymer lithium ion battery overview of lithium ion battery according to the use of materials can be divided into liquid lithium ion battery electrolyte ( 自由) And polymer lithium ion battery, 嘴唇) 。 Polymer lithium ion battery and lithium ion liquid using the same material of the positive and negative, same cells work. The main difference lies in the electrolyte. Lithium ion battery using liquid electrolyte and polymer lithium ion battery with a solid polymer electrolyte replacement. Solid polymer electrolyte can be either a 'dry', also can be 'of the colloid, mainly composed of polymer gel electrolyte. Polymer lithium ion battery can be divided into three categories: ( 1) Solid electrolyte of lithium ion battery. The electrolyte is a mixture of polymer and salt. This kind of battery low ionic conductivity at room temperature, suitable for high temperature use. ( 2) Gel polymer electrolyte of lithium ion batteries. In the solid polymer electrolyte adding plasticizer and other additives, improve the ionic conductivity, the battery can be used at room temperature. ( 3) Polymer cathode materials of lithium ion batteries. Conductive polymers as cathode materials, the ratio can be three times the current lithium ion battery and lithium ion battery is the latest generation. Replace liquid electrolyte, with a solid electrolyte and liquid lithium ion batteries, polymer lithium ion batteries have thin shape change, any field with arbitrary shape, and so on, also won't produce leakage and combustion explosion safety problems, so you can use lu: su composite membrane manufacturing battery shell, can improve the specific storage battery; Polymer, polymer lithium ion battery can also be used as the anode material, its quality than the energy will be more than 50% higher than the current liquid lithium ion battery. In addition, the polymer lithium ion battery in the working voltage, charge and discharge cycle life than lithium ion battery has improved. Based on the above advantages, polymer lithium ion battery is referred to as the next generation of lithium ion batteries.
