Ternary polymer lithium battery.102450 polymer battery

  Ternary polymer lithium battery refers to the lithium battery whose cathode material is lithium nickel cobalt manganate (Li (NiCoMn) O2) ternary cathode material and uses gel polymer electrolyte. As the transmission medium of ion movement, electrolyte is generally composed of solvent and lithium salt. The electrolyte of lithium secondary battery mainly includes liquid electrolyte, ionic liquid electrolyte, solid polymer electrolyte and gel polymer electrolyte. Gel polymer electrolyte is composed of polymer, organic solvent and lithium salt, which is prepared by mixing organic electrolyte and solid polymer matrix. Because it exists in the form of gelled state, it has the advantages of both solid electrolyte and liquid electrolyte. Because the electrolyte is limited in the polymer chain, it also has high ionic conductivity (up to 10-3S/cm) in a wide temperature range. Its biggest advantage is the high mechanical strength of the diaphragm, and the thin film provides a large surface area. The thinner the thin film, the higher the energy density, as more active substances can be embedded in the battery. In addition, its electrochemical stability is also very good, and it is resistant to high temperatures. Most high-temperature batteries on the market use polymer electrolytes.
