Why Laptop battery reduces its efficiency? Tech Focus 9


Laptop battery is a kind of Lithium Ion ( Li-ion) battery which has features like high efficiency, slow discharge rate, best energy to weight ratio etc.Unlike other rechargeable batteries, Lithium ion battery uses Lithium as the active material. During discharge, the lithium ions move from the negative electrode to the positive electrode. The flow of lithium ions reverse during charging. Lithium Ion battery outperforms other types with its features like High open circuit voltage that deliver high power at low current rate, Low self discharge rate of 5-10% per month etc. But along with these advantages, lithium ion battery has demerits also. Memory effect, self discharge, over heating etc are the most important drawbacks of Laptop battery. Let us see how this happens and the solutions to prevent this.
