Chinese battery manufacturer CATL has begun mass production of a new lithium iron phosphate (LFP) cell for stationary energy storage systems. According to the company, the 587 Ah cell was developed and tested over a span of three years. The goal was to achieve higher energy density with fewer components while adhering to regulatory and safety requirements.
Less battery modules and housings required
The cell is designed for use in 20-foot containers with 1,500 volt power converters. The new cell format aims to reduce the number of battery modules and housings required. CATL estimates a reduction in system components from 30,000 to 18,000. The company cites a volumetric energy density of 434 watt-hours per liter and a system efficiency of 96.5 percent. Electrochemical modifications, including a self-healing electrolyte, are intended to extend the service life.
