Performance of lithium-ion batteries.3.7v 2200mah 18650 lithium battery

  The diaphragm is located between the positive and negative poles, and its main function is to separate the active substances of the positive and negative poles, preventing short circuits between the two poles due to contact; In addition, during electrochemical reactions, the necessary electrolyte can be maintained to form channels for ion movement. The material of the separator is non-conductive, and different types of batteries use different separators. For lithium-ion batteries, as the electrolyte is an organic solvent system, the separator requires the following performance.

  ① In the battery system, its chemical stability is good, and the materials used are resistant to organic solvents.

  ② High mechanical strength and long service life.

  ③ The ionic conductivity of organic electrolytes is lower than that of aqueous solution systems. In order to reduce resistance, the electrode area must be as large as possible, so the membrane must be very thin.

  ④ When there is an abnormality in the battery system, the temperature rises. To prevent danger, at the beginning of rapid heat generation temperature (120-140 ℃), the thermoplastic membrane melts, the micropores close, and becomes an insulator, preventing electrolyte from passing through, thus achieving the purpose of interrupting current.

  ⑤ From the perspective of lithium batteries, they should be able to be fully immersed in organic electrolytes and maintain a high degree of immersion during repeated charging and discharging processes.

  The commonly used separator material in batteries is usually a microporous membrane made of cellulose or woven fabric or synthetic resin. Lithium ion batteries generally use high-strength, thin-film polyolefin based porous membranes, commonly used membranes include polypropylene (PP) and polyethylene (PE) microporous membranes, as well as copolymers of propylene and ethylene, and polyethylene homopolymers.
