Cornex unveils 472 Ah LFP cell enabling more than 7 MWh in a 20-foot container

From ESS News

On March 28, CORNeX, a lithium battery maker headquartered in Hubei Province, unveiled its fourth-generation ​ lithium iron phosphate (LFP) energy storage cell with a capacity of 472 Ah.

Measuring ​74mm×220mm×225mm, the cell builds on the architecture of its predecessor, the ​314Ah “Long π” cell, preserving its proprietary material formulations and automated production processes. This continuity ensures ​high reliability, thermal stability, safety compliance, and manufacturing consistency, while achieving a quantum leap in performance, the manufacturer said.

The ​1,510.4 Wh nominal energy per cell marks a ​50% surge over the 314 Ah model, driven by a ​195 Wh/kg gravimetric energy density and ​420 Wh/L volumetric density, figures that edge tantalizingly close to the theoretical ceiling for LFP chemistry.
