Williams Advanced Engineering, the engineering services and technology business of the Williams Group, has entered a partnership agreement with XALT Energy, supplier of the lithium-ion cells for the Williams’ battery in the Formula E racing series. This new partnership will also see the two companies collaborate on future projects involving lithium-ion battery technology for a range of applications beyond motorsport.
Williams Advanced Engineering and XALT Energy have worked closely together since June 2013 after Williams was awarded the contract to produce the batteries that will power all 40 cars competing in Formula E, the world’s first fully electric racing series.
XALT currently offers a range of high-energy and high-power Nickel Manganese Cobalt (NMC) prismatic Li-ion cells with capacities from 25 Ah up to 75 Ah.

XALT Energy have supplied the lithium-ion cells for each battery and have been integrated into the Williams team to ensure that the batteries meet stringent performance, reliability and safety criteria. FIA regulations state the cell weight has to be limited to 200kg and the output of the battery can be no more than 28 kW/h, so Williams designed a battery with some excess stored energy levels that stayed within the FIA regulations via the incorporation of XALT Energy cells.
As part of this new partnership agreement XALT Energy will become an Official Partner of Williams Advanced Engineering, with the company’s logo featuring on the Williams Advanced Engineering website and other marketing materials.
