Product Description
Descriptions:
The positive pole materials of this PA-1650-02HC HP Compaq 65W laptop AC adapters are always demanding additives to sustain its activeness of charge and discharge for several times, and its negative pole materials need molecular structures to design and accommodate more lithium. The electrolyte that stays between the two poles of the battery, apart from the sustainment of its stability, needs good conductivity, so as to reduce its internal resistance. Although this battery has very little memory effect, the principles of which are aimed at crystallization, there will not take place such reaction in the battery belonging to the Li-ion battery series. Yet the capacity of this battery, after being charged and discharged for several times, will still decrease, the reason for which is quite complicated and various.
The reaction results mainly from the alteration of the two poles materials in themselves. From the point of view of the molecular layer, the empty structure that accommodates lithium on the two poles will gradually sink and become blocked; from a chemical perspective, it is the active passivation of the two poles materials which produces sub-reactions that generates other stable chemical compounds. Physically, there is likely to take place a situation where the positive pole materials are gradually peeled off, which, all in all, reduces the amount of lithium that can move in the course of the free charge and discharge of the PA-1650-02HC HP Compaq 65W laptop AC adapters.
