  The SEI membrane is not simply covered with the electrode surface, and the membrane component has a structural connection with the atom or atomic group of the electrode interface. This is a necessary guarantee to ensure the stability of the SEI film component. There are a small amount of acid groups such as -OH and -COOH on the interface. During the electrode process, it is easy to change to-OLI or carboxyl lithium salt in the process of electrodes, so that it can stably exist on the electrode/electrolyte interface. The oxidized graphite can quickly form a stable SEI membrane in EC and EMC, thereby reducing irreversible loss of the electrode.

  The composition of electrolytes largely determines the chemical composition of the SEI membrane. For different chemical composition, the structure and nature of the membrane must be different, so the composition of the electrolyte is the key to affecting the nature of the SEI membrane.

  It is generally believed that high temperature conditions will reduce the stability of the SEI membrane and the worse of the electrode cycle performance. This is because high temperature conditions accelerate the dissolution of the SEI membrane and the joint embedding of the solvent molecules, while the SEI membrane formed under low temperature conditions is dense, stable and low in impedance, but the SEI membrane formed under low temperature conditions is easy to decompose when it encounters high temperature.

  Because the diffusion speed of various ions is different from the number of ions migration, the electrolyte component of the carbon negative surface is actually the result of a variety of reaction competition. Therefore The composition of the membrane is different. Studies have shown that current density has little effect on the thickness of the membrane, but the composition of the membrane can be significantly changed.
