What Happens: The surface of the negative electrode has a layer of film called SEI film, this film in the use of a long time lithium battery, slowly will be consumed and broken, but it will also form a new SEI film, this reaction will cause the consumption of lithium ions and electrolyte, sometimes the negative surface of the SEI because of excessive aggregation, and the occurrence of tunnel congestion, this time the efficiency becomes low, It also reduces the cycle life of lithium-ion batteries.
Solution: Choose more suitable for LITHIUM ion battery PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC iron removal anode material for reaction. The energy density of the cathode material refers to the energy size of 1 milliliter of the cathode material, generally speaking, the energy size of a unit volume; Another explanation is that the amount of energy per unit mass of the cathode material, colloquially, is the amount of energy per unit mass.
The energy density of the cathode material is related to the energy and volume released per unit volume given. Given a given volume, the greater the energy, the greater the energy density. The higher the energy density, the smaller the volume in the case of energy phase; The higher the energy density, the higher the energy at a given volume. PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC is used for iron removal from cathode materials.
