Lithium-ion battery positive electrode material manganese dioxide is a tight component, and the chemical reaction of charge and discharge is used, and the addition component is to improve the performance of the battery. Lithium ion battery negative electrode material metal lithium or its alloy metal is an negative electrode material, these things are coated on copper foil, and the negative is on. In the lithium ion battery material, the negative electrode material belongs to a desired component, which can have a large effect on the performance of the overall battery.
At present, the negative electrode material is divided into two categories, one for commercially used carbon materials, such as natural graphite, soft carbon, etc., the other is in the development state, but in the future, a good non-carbon negative material, For example, silicon-based materials, alloy materials, tin gold materials, etc. The positive electrode (cathode) BAI manganese dioxide is a critical component, and the chemical reaction of charge and discharge is used.
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 ~ 4) : 1), because the performance of the positive electrode material is directly affected by the performance of the lithium ion battery, and the cost is also determined by the battery cost; the negative electrode (anode) metal lithium or its alloy metal is a negative electrode material, these things are applied to copper foil, negative electrode Happened. Rated capacity: Under design specified conditions (such as temperature, discharge ratio, termination voltage, etc.), the battery should be able to release the lowest capacity, unit is amps / hour, expressed in symbol C.
The capacity is larger than the discharge rate, so it is often labeled with the discharge rate in the lower right corner of the letter C, such as C20 = 50, which is declared at 20 yards of 50 hours. 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 according to Faraday. Due to the special side effects of the battery, the actual capacity of the battery is often lower than the theoretical capacity.
Rated voltage: Typical operating voltage at normal temperature, also known as nominal voltage. It is a reference when choosing different kinds of batteries. The actual operating voltage of the battery is equilibrated with different use conditions, equilibrium electrode potential of the negative electrode.
It is only related to the type of electrode active substance, and has nothing to do with the number of active substances.
