In the field of battery industry, the charge-discharge rate is usually used to describe the relationship between charging speed and current size.When we customize lithium battery, charge-discharge rate is a important factor to consider.For example, the rate of 1 hour full battery is called 1C, the rate of only 30 minutes is called 2C, and so on, more than 1C can be
As widely acknowledged, the de-solvation process of lithium ions from organic liquid electrolytes to the surface layer of electrode is the rate-limiting process in lithium-ion batteries (LIBs). Based on this cognition, effective strategies have been developed to realize low-temperature LIBs.
Selecting a lithium-ion battery for a certain application depends mainly on the chemistry of cathode and other physical factors involved in the fabrication of cells, e.g. density of the material, composition and solid particle size in electrodes, and the cell geometry.
