With the development of global diversification, our lives are constantly changing, including the various electronic products we come into contact with. With the continuous improvement of the requirements for the capacity of lithium-ion batteries by electrical equipment, people have higher and higher expectations for the improvement of the energy density of lithium-ion batteries. In particular, various portable devices such as smart phones, tablet computers, and notebook computers place higher requirements on lithium-ion batteries that are small in size and have a long standby time. Also in other electrical equipment, such as: energy storage equipment, power tools, electric vehicles, etc., are constantly developing lithium-ion batteries with lighter weight, smaller volume, higher output voltage and power density, so the development of high energy density Lithium-ion batteries are an important research and development direction in the lithium battery industry.
A high-voltage battery refers to a battery whose battery voltage is relatively higher than that of an ordinary battery. According to battery cells and battery packs, it can be divided into two types. The high-voltage battery is defined from the voltage of the battery cell. This aspect is mainly for lithium batteries. At present, the types of lithium battery cells mainly include high-voltage lithium battery cells and low-voltage lithium battery cells. High-voltage lithium battery cells have higher energy density and lower safety performance than low-voltage batteries, but their discharge platform is relatively high. Under the same capacity, high-voltage batteries are lighter than low-voltage batteries in terms of volume and weight.
In terms of the discharge rate of high-voltage and low-voltage batteries, high-voltage lithium batteries have a higher discharge rate and stronger power than low-voltage lithium batteries. Therefore, in theory, high-voltage battery cells should be more suitable for use in products and equipment that require high-rate discharge. , In order to make better use of its advantages.
