Wat is Energy Storage Battery Cell？
An Energy Storage Battery Cell is the basic unit within an energy storage system (ESS) that stores electrical energy in the form of chemical energy. It consists of positive and negative electrodes, an electrolyte, and a separator. The cell works by the flow of ions between the electrodes during charge and discharge cycles, converting chemical energy into electrical energy and vice versa. There are various types of battery cells, each with unique characteristics, such as lithium-ion, lead-acid, and nickel-metal hydride. Among them, lithium iron phosphate (LiFePO4) cells have gained significant popularity, particularly in energy storage and electric vehicle applications. This type of cell offers advantages such as high thermal stability, long cycle life, and enhanced safety compared to other lithium-based batteries, making it a preferred choice for many renewable energy solutions and large-scale energy storage systems.
The 280Ah LiFePO4 battery offers reliable, efficient energy storage. With a nominal voltage of 3.2V, it supports a 1.0C discharge rate and features low internal resistance (<0.25mΩ). The battery charges at 1C (cut-off voltage 3.65V) and discharges at 1C (cut-off at 2.5V). It supports fast charging, reaching full capacity in 2 hours (0.5C) or 1 hour (1C). With a cycle life of over 6000 cycles at 70% SOH, it ensures long-term durability. The battery operates within a temperature range of -20°C to 55°C for discharge and 0°C to 55°C for charging.
At Dagong ESS, we offer a variety of battery cells that meet the needs of different applications, as outlined below:
Capacity (Ah): The amount of charge a battery can hold, often expressed in ampere-hours (Ah). It determines how long a battery can supply power to a system.
Cycle Life (Cycles): The number of complete charge and discharge cycles a battery can undergo before its capacity falls to 80% of its original value.
Charge and Discharge Rate (C rate): The rate at which a battery can be charged or discharged, expressed as a multiple of the battery's capacity. A 1C rate means charging or discharging at a rate equal to the battery's capacity per hour.
Operating Temperature Range (°C): The temperature range in which the battery can operate efficiently. It is important for ensuring the battery performs optimally in different environments.
