Motorsports
McMurtry Automotive: Faster cell evaluation
McMurtry Automotive used The Voltt and validated cell models to evaluate the transition from the Molicel P45B to P50B during early pack concept development.
Side by side modelling enabled rapid comparison of electrical and thermal behaviour, avoiding lengthy physical test campaigns. This approach reduced cell evaluation time by seven months, allowing the team to lock in cell selection and pack assumptions earlier while lowering technical risk and accelerating vehicle development.

Manufacturer Background
Enpower Greentech
Enpower Greentech is an American developer of lithium-metal and solid-state cells
Enpower Greentech was founded in California in 2012 and develops lithium-metal and all-solid-state batteries alongside the key materials they depend on. Its research and manufacturing centres are based in China and Japan, with further operations in the United States and Germany. The company produces lithium-metal pouch cells at energy densities well beyond conventional graphite-anode lithium-ion, including some of the lightest high-capacity lithium-metal cells built to date, aimed at uncrewed aircraft and other endurance-limited platforms. Its technical programme has drawn on collaborations with academic groups in the United States and Japan, and the company is venture backed. Enpower sits among the developers moving lithium-metal chemistry from demonstrators into qualified production cells.
