New method of prolonging the life of lithium battery

Tom Hartley, a professor of electronic engineering at the University of arkland, who helped the US space agency NASA study to extend battery life, said: The deeper the lithium battery discharged, the greater loss of the battery. The more charged for li ion battery, the greater loss of the battery. Lithium batteries are best placed in the middle state of electricity. In that case, battery life is the longest.

First, too high and too low power consumption is the most unfavorable to the life of lithium battery, and the number of charge and discharge cycles is secondary. In fact, most of the charging and discharging times on the electrical appliances or batteries are based on discharge eighty percent. The experiment shows that for some laptop lithium ion batteries, the battery voltage is more than the standard voltage 0.1V, that is, from 4.1V to 4.2V, then the life of the lithium battery will be halved and the 0.1V is increased, then the life of the lithium battery is reduced to the original 1/3; the li ion battery is in the low or no electricity state for a long time. The resistance is increasing, resulting in smaller battery capacity. NASA makes the lithium battery consumption on its Harbert space telescope set at 10% of the total capacity.
