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.
