CORNeX unveils 472 Ah LFP cell enabling more than 7 MWh in a 20-foot container
The Chinese battery maker has launched its next-gen lithium iron phosphate cell which can be integrated with both 1,500 V and 2,000 V platforms. It plans to establish mass production by June 30 with an annual manufacturing capacity layout of more than 80 GWh.

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 p” 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.
Under rigorous testing, the cell demonstrates 12,000 full charge-discharge cycles at 70% state of health (SOH), extendable to 15,000 cycles via CORNeX’s patented cathode pre-lithiation technology. Crucially, it sustains zero performance degradation even in 35°C ambient environments, a critical advantage for deployments in tropical regions or industrial settings with limited cooling infrastructure.
When integrated into 1,500 V energy storage systems, a standard 20-foot container packed with 472 Ah cells delivers 6.28 MWh of capacity, 40% higher than previous iterations, with scalability to 6.9 MWh. This innovation slashes land footprint by 20% and reduces levelized storage costs by over 20%, according to company simulations.
For future-proofing, the design accommodates 2,000 V high-voltage platforms, pushing single-container capacity to 7.06 MWh, a 12.4% boost that positions it as a frontrunner for utility-scale projects.
Capitalizing on mature supply chains and existing gigafactory lines, CORNeX plans global sampling from April 25, followed by mass production by June 30, leveraging an 80 GWh annualized capacity to outpace rivals in commercializing jumbo-format cells.
Pre-orders already reflect surging demand: preliminary 2024 data show over 30 GWh in energy storage system contracts and more than 20 GWh shipments, despite unaudited financials. Analysts note these metrics align with global projections for LFP dominance, expected to capture 70% of stationary storage markets by 2030.
