Low temperature ion conductivity change

The aqueous solution is easy to solidify into ice at low temperature, which leads to the sudden drop of ionic conductivity and makes the supercapacitor unable to work at low temperature.

Generally, it has high conductivity at low temperature and is suitable for use in low temperature ion batteries. Empirical conductivity equation: Because the electrolyte concentration of lithium-ion batteries is generally 1mol/L or even higher.

The ionic conductivity is increased by 100 times, and it can be applied at low temperature (0-25℃), realizing the uniform deposition of lithium. The modified PEO-based electrolyte can also make Ferrous lithium phosphate anode available at room temperature.
