(1) Solid polymer electrolyte lithium ion battery

    The electrolyte is a mixture of polymer and salt, and the battery has a low ionic conductivity at room temperature, making it suitable for high temperature use.

    (2) Gel polymer electrolyte lithium ion battery

    That is to add plasticizer and other additives in solid polymer electrolyte, so as to improve ionic conductivity, so that the battery can be used at normal temperature.

    (3) Lithium-ion battery with polymer cathode material

    Using conductive polymer as cathode material, its specific energy is 3 times of the existing lithium ion battery, is the latest generation of lithium ion battery.By using solid electrolyte instead of liquid electrolyte, compared with the liquid lithium ion batteries, polymer lithium ion battery has thin shape is changed, any area with arbitrary shape, etc, also won't produce leakage and combustion explosion safety problems, so can use lu: su composite membrane manufacturing battery shell, which can improve the specific storage battery;Polymer lithium-ion battery can also use polymer as cathode material, its mass ratio energy will be more than 50% higher than the current liquid lithium-ion battery.In addition, polymer lithium-ion batteries are better than lithium-ion batteries in terms of working voltage and charge-discharge cycle life.Based on the above advantages, polymer lithium ion battery is regarded as the next generation of lithium ion battery.Lithium ion battery is a new type of battery with higher energy density, miniaturization, thinness, lightweight, high safety, long cycle life and low cost.Therefore, in the next 2 ~ 3 years, the market share of polymer lithium battery replacing lithium ion battery will reach 50%.
