Korea sodium ion batteries come: better performance than lithium-oxygen batteries
A research team from South Korea recently demonstrated the new room temperature and a high energy density sodium-ion rechargeable batteries, using inorganic molten sulfur based composite cathode electrolyte, can serve as a sodium ion conductive electrolyte and cathode material.
According to the sum of the mass of the cathode electrolyte and carbon electrodes, the discharge capacity of the new sodium ion battery of 153 mAh / g, the working voltage of 3 V; excellent battery at high current charge and discharge performance, charge-discharge cycle performance is is outstanding, it is possible more than 300 times. Particular note is the new inorganic liquid electrolyte has flame resistance and self-reconstruction of features that will help accelerate the commercialization of the sodium-ion rechargeable battery pack process.
