Eve Energy presents cylindrical cells with 6C charge rate
Eve Energy announced the cylindrical cell this week at its first lithium battery conference, which the company combined with its 23rd-anniversary celebration. According to media reports, Zhao Ruirui, Senior Vice President of Eve Energy’s Central Research Institute, gave a presentation on the development status of several projects.
The company’s research institute head introduced the Omnicell cylindrical cell, which is designed to support a charging rate of 6C. He also mentioned the company’s progress in the areas of eVTOL batteries and solid-state batteries. The introduction of solid-state batteries is expected in 2026.
Other than the 6C charging rate, further details on Eve Energy’s Omnicell cylindrical cell are not yet available. The “C” is an indicator of the ratio of battery size to charging capacity. At 1C, an 80 kWh battery can be charged with a maximum of 80 kW. At 6C, the same battery can theoretically be charged with six times the charging capacity – i.e. up to 480 kW. The company calculates that a 6C fast charging capability can give electric vehicles a range of 300 kilometres in just 5 minutes of charging.
The first Chinese electric vehicles are currently being offered with 5C batteries. This includes the Li Mega from Li Auto, which recently announced plans to build more than 10,000 of its fast-charging stations in China by 2025. 5C batteries are also installed in the current version of the Zeekr 007. According to the latest reports in the Chinese media, CATL and BYD are also said to be working on 6C batteries, with CATL planning to launch a new generation of its Qilin battery with a charging rate of 6C in the second half of 2024.
Eve Energy is primarily active in China but is expanding internationally and currently building its first European plant in Hungary to supply BMW. Large-volume cylindrical cells for BMW’s New Class are to be produced in Debrecen, representing a volume of up to 28 GWh per year.
Just this March, Eve Energy also concluded a production agreement with the Israeli battery specialist StoreDot, whereby StoreDot has secured part of Eve’s production capacity for its extremely fast-charging battery cells. StoreDot intends to market these cells, but Eve Energy will also manufacture such cells under license and market them itself.
