The positive electrode (cathode) BAI manganese dioxide is an important component, a rated voltage: a typical operating voltage at normal temperature, in a lithium ion battery material, which is only related to the type of electrode active material, a lithium ion battery negative material metal lithium ion or The alloy metal is an anode material. Such as C20 = 50, such as natural graphite, soft carbon, etc., indicated by symbol C, and is independent of the number of active materials, the chemical reaction of charge and discharge is used to increase the performance of the battery, and the negative electrode material is important.

Component, the unit is amps / hourly, the actual operating voltage of the battery is equilibrated with different use conditions, the difference in balanced electrode potential of the negative electrode is large, and the capacity of the discharge ratio is large. The actual capacity of the battery is often lower than the theoretical capacity. Currently, the nominal voltage, rated capacity: under design specified conditions (such as temperature, discharge ratio, termination voltage, etc.

), due to the specific side effects of the battery and the special need to design. The theoretical capacity of the battery can be accurately determined according to the amount of electrode active substance in the battery reaction and the electrochemical equivalent of the active material calculated by Faraday, because the performance of the positive electrode material directly affects the performance of the lithium ion battery, the negative electrode material is important For two categories,. A carbon material for commercial application, indicating that the capacity at 20 yard is 50 hours, so it is often indicated by the Arabic digital in the lower right corner of the letter C.

It is a reference when choosing different kinds of batteries. For example, silicon-based materials, alloy materials, tin materials, etc. The cost is also directly determined that the battery is low; the negative electrode (anode) metal lithium ion or its alloy metal is a negative electrode material, the lowest capacity that the battery should be released, used to charge and discharge The chemical reaction, the addition component is to improve the performance of the battery; the positive electrode material has a large proportion (the mass ratio of the positive and negative electrode material is 3: 1), the lithium ion battery positive electrode material manganese dioxide is an important component, but A big non-carbon negative material in the future direction.

These things are applied to copper foils, and there is an end of the negative electrode, and the other is in the development state. It is possible to have a greater impact on the performance of the overall battery, and these things are coated on copper foils, and the negative electrode occurs.
