China’s XYZ launches 261 kWh immersion-cooled commercial battery

Chinese manufacturer XYZ has launched a 125 kW/261 kWh immersion-cooled battery branded as Galaxy Immersion, which submerges its battery cells in a dielectric liquid which can store an electrical charge but has poor electrical conductivity.

That fire-safety measure, developed in coordination with scientists at Tsinghua University, eliminates the risk of fire and explosion and makes the product ideal for use with data centers, hospitals, shopping malls, and metro stations, according to Zha Qing, senior manager of overseas market development at XYZ’s International Business Department.

The Galaxy Immersions’ fire safety measures also make it attractive for installations which lack constant monitoring and dedicated personnel, as many commercial batteries do, said Qing, who spoke to pv magazine at May’s Intersolar Europe trade show.

The Galaxy enables high-power electric vehicle charging in urban areas, providing a safer and quieter alternative to traditional air- or liquid-cooled systems, said Qing, adding its compact design and ability to integrate into small spaces makes it easy to install near critical infrastructure.

The executive said the safety advantages of the Galaxy have become obvious after fire incidents involving non-immersion-cooled batteries at hotels and commercial buildings.

The elimination of the possibility of thermal runaway in XYZ’s Galaxy devices – which are on sale now – significantly reduces the possibility of battery fires spreading in densely populated areas.

XYZ manufactures at its plant in Beijing and its systems offer market support, artificial intelligence-assisted decision-making to optimize charging and discharging cycles, and weather forecasting.

Founded in 2021, manufacturer XYZ has completed, and is working on 13 GWh of energy storage capacity in Chile, Mexico, and Kazakhstan. The company also offers electricity frequency regulation projects for thermal power plants.

XYZ’s first project was at the Peñasco solar farm in Mexico, in April 2023.

Part of China’s state-owned State Power Investment Corporation (SPIC), XYZ is part of an international power company which controls 260 GW of generation capacity in China, Kazakhstan, Pakistan, Vietnam, Brazil, Chile, Australia, Malta, and Germany.

In Mexico, SPIC owns Zuma Energía, which manages 1.3 GW of wind assets. In Brazil, SPIC operates hydroelectric dams, solar farms, combined-cycle plants, and wind sites. The company has also completed significant projects in Chile.
