Chinese energy tech company CORNEX has launched a 588Ah large-capacity battery together with a new ‘Transformers’ system platform to provide rapid deployment support for energy generation and grid support applications.

The new 588Ah cell features a mass energy density of 190 Wh/kg and a volume energy density of 419 Wh/L. The company reports an energy efficiency of 96.5%.

CORNEX has also introduced a 588-CTP2.0 energy storage PACK. This design is reported as reducing the variety and quantity of materials by 20%. At the pack level, it achieves a mass energy density of 170 Wh/kg and a volume energy density of 285 Wh/L.

For safety, the PACK incorporates a 1,000 °C heat-resistant isolation layer to prevent thermal runaway propagation from the cell to the system level. The company reports that a proprietary “absorption and protection” manufacturing process has increased production efficiency by 35%, boosting its capacity for large-scale delivery.

The new “Transformers” system is designed as a modular platform. It is aimed for rapid deployment and employs standard containers, such as a 3.13 MWh 10-foot unit and a 6.26 MWh 20-foot unit. These can be combined as building blocks to meet specific project requirements in power, capacity, and site conditions.

According to the company, it is aimed at applications such as power generation, grid support, and large-scale commercial and industrial use.

CORNEX states that implementing the “Transformers” platform on a 100-megawatt-scale project can lead to savings including a 20% reduction in land footprint, a 27% decrease in the number of BESS, and a reduction in operational costs by over 20%.
