Solid-state Ion Battery

At present, most of the conventional electrode materials (active materials) are in powder form, in manufacture that electrodes from the powder material, conductive agents and binders such as PVDF need to be added, the binder is mainly used to bond and maintain the active material, stabilize the electrode sheet structure, and enhance the contact between the active material and the conductive agent and current collector. However, the non-conductive binder increases the electrode resistance and is not conducive to lithium ion transport, Therefore, in various electronic and electric equipment applications, the preparation of adhesive-free film electrodes has become an inevitable trend. The electrode material prepared by a chemical method is a powder material, which must be mixed with a conductive agent and a binder and then coated on a current collector to produce an electrode. Although the preparation cost is quite low, the yield of good products is too low because of too many uncontrollable conditions. The thin film deposition method can directly deposit the electrode material on the current collector to form thin film electrode, the preparation process is simple and does not need to mix conductive agent and binder, and the yield of good products is greatly improved. Based on the safety survey, all-solid-state battery has become an inevitable trend in the future.
