Power battery focus more on charging and discharging power aspect, requiring fast charging rate, high output power, vibration resistance, especially emphasizing higher safety and high energy density to achieve lasting endurance, as well as light weight and volume requirements. From the aspect of battery materials, it is necessary to consider the lithium storage performance of anode and cathode materials as well as the related performance of electrolyte and diaphragm.

But the portable power station emphasizes the battery capacity, especially the operation stability and service life. The consistency of battery module should be considered. In terms of battery materials, the expansion rate, energy density, electrode material performance uniformity and other aspects should be paid attention to in order to pursue the long life and low cost of the overall energy storage equipment.

Take OPS600 of portable station for example, 576Wh battery capacity, then the cycle life of battery can reach 1000 times, if you run a cycle once a week, this power station will be used about 20 years. High quality battery materials determine the portable station stability.
