Chinese battery giant CATL says it has entered a new technology partnership with the prestige luxury brand Rolls-Royce to power its static energy storage systems.

The German-owned automaker, which assembles its products at Goodwood near the U.K.’s south coast, is set to deploy CATL’s latest Tener technology in its mtu EnergyPack QG solution, Chinese automotive website CnEVPost reports.

On-site energy storage batteries help companies perform grid management and energy trading services in the move toward a more sustainable use of clean electricity.

The two companies are also partnering on engineering, procurement and construction projects to jointly provide energy management services, CATL says. In line with German automakers’ close relationship with Chinese manufacturers, the two companies already team up in European energy storage products such as EnerOne.

CATL claims its Tener system is the world's first mass-produced energy storage system guaranteeing zero degradation within a five-year timeframe. It’s a standard 20 ft. (6.1 m) container energy storage system equipped with energy storage-specific L-series long-life lithium iron phosphate cells.

The system claims an energy density of 430 Wh/L and a total capacity of 6.25 MWh, which CATL says is the highest in the world. It also claims a lifecycle of more than 15,000 cycles, nearly twice the current mainstream level, and 20-year life expectancy.
