LARGE CAPACITY ENERGY STORAGE BATTERIES IN DACCA

Energy storage battery capacity reduction in low temperature environment

However, LIBs usually suffer from obvious capacity reduction, security problems, and a sharp decline in cycle life under low temperatures, especially below 0 °C, which can be mainly ascribed to the decrease in Li + diffusion coefficient in both electrodes and electrolyte, poor transfer kinetics on the interphase, high Li + desolvation barrier in the electrolyte, and severe Li plating and dendrite.

Peak-shaving and valley-filling energy storage batteries

Due to the fast charging and discharging characteristics of battery energy storage system, it is charged during low load periods and discharged during peak load periods, thereby shaving and filling the power load of isolated microgrids, alleviating the power generation pressure of microgrids during peak power consumption, ensuring the reliability of microgrid power supply, and reducing the number of start and stop times of generator units during low power consumption periods, thereby increasing the micro increase rate of power consumption of generator units.
