The number of battery charging and discharging is critical. How to increase it?

NASA's Jet Propulsion Laboratory has developed a new type of lithium anode electrochemical battery that can increase the number of charge and discharge of rechargeable lithium batteries. Although the old secondary lithium battery has a better storage function, the cycle life of the lithium battery is shorter because the components of the lithium battery are incompatible in physical and chemical properties. After many cycles, the cathode is easily decomposed. The new type of lithium battery is made of a material with a liquid content equal to the electrolyte, which is moist and chemically stable. The low evaporation power and good electrochemical stability of the dielectric improve the packaging and safety of the battery. In addition, the battery can work at a moderate temperature below 100°C, so it is suitable for motor vehicles, communications and other aspects. This new type of lithium battery has a lithium anode, a titanium disulfide cathode and an electrode composed of LIA3F6. The separator is coated with a surface activator, which contains a special binding force formula in the cathode, which is compatible with the new electrode. The results show that the cycle life of the battery is twice that of the best battery. For example, for sulfoxide-based dielectric fluids, 3MeS is a heterocyclic compound. The reason why these compounds are chosen as dielectric fluids is that they have stronger oxidation and reduction capabilities than the commonly used 2MeTHF dielectric fluids. . In addition, the dielectric has the characteristics of low melting point and high boiling point, so the application of temperature is more extensive. But at the same time, they have high polarity and cannot wet the non-polar substances in the separator. Therefore, the surface of the liquid separator should be coated with waolin or si-bdrunkimidroprid as a surfactant. These substances can wet the dialyzer without affecting the stability of the electrodes. In order to improve the mechanical stability of the cathode, ethylene-polyvinyl chloride is used as the binder of its polymer to replace the polytetrafluoroethylene used in the past. Since the material cannot be wetted by the dielectric fluid, a sulfoxide compound is added to maintain its wettability.
