Revolutionary Electric Vehicle Battery (REVB)

A new lithium-sulfur battery aims to double the energy stored per kilogram compared to today’s electric vehicle batteries, reaching 400 watt-hours per kilogram. Current electric car batteries rely on lithium-ion chemistry, which is approaching its theoretical energy limits. This project tackles a fundamental gap: battery developers rarely use computer models to guide their chemistry experiments. By embedding a model-led research culture at OXIS Energy, working with Imperial College, the team intends to accelerate improvements in lithium-sulfur cells—a chemistry that already promises higher energy density but has struggled with cycle life and performance. If successful, the battery system could store more energy and also harness significantly more of that energy, delivering a compound improvement in vehicle range. The project also develops a battery energy manager with Lotus and Cranfield to push the chemistry to its limits while maintaining practical cycle life. This would put the UK in a leading position to manufacture next-generation electric vehicle batteries, reducing reliance on foreign supply chains for battery technology. For drivers, the most visible change would be longer range between charges, but the deeper impact is on manufacturing competitiveness and energy infrastructure.
