The so-called power battery refers to the battery that supports high rate and high current discharge, has high power density, and releases more energy per unit time. The rate discharge capacity refers to the ability of a battery to maintain its capacity when the charge discharge rate increases. The rate of charge and discharge is expressed as xC, where 1C means that the nominal capacity of the battery can be used up in 1 hour, while discharging at a rate of 2C can last for 30 minutes.
The power/rate performance of a battery is closely related to its design and is influenced by various factors, such as electrolyte, separator, type of active material, size of active particles, and so on. Among these factors, the thickness of the electrode is the main factor affecting the high current discharge capacity. The rate discharge capacity can be greatly improved by thinning the electrode, as the thin electrode has smaller electronic and ion impedances. However, thinning the electrode results in less active material mass inside the electrode, resulting in a decrease in battery capacity. So the main technical challenge for ternary power lithium batteries is to increase their high current discharge capacity without reducing capacity.
For ternary lithium-ion batteries, Panasonic Corporation of Japan is currently the most researched and technologically mature company. During the experimental phase, it has been able to achieve 30C discharge. Among them, the 18650 ternary lithium-ion battery, which has been successfully commercialized and mass-produced, has a discharge rate of 12C and a capacity of up to 3300mAh. There are also manufacturers in China that achieve high discharge rates, but the stability of batteries still needs to be improved, especially after a period of use, their cycle life and rate discharge capacity will be greatly reduced. There are research reports that the rate performance of lithium batteries can be improved through methods such as particle coating and modification.
