Ababa Battery

Owing to the low-cost, low-flammability and three-electron redox properties of aluminium (Al), rechargeable Al-based batteries could in principle offer cost-effectiveness, high capacity and safety, which would lead to a substantial advance in energy storage technology 3, 8.

The development of new rechargeable battery systems could fuel various energy applications, from personal electronics to grid storage 1, 2. Rechargeable aluminium-based batteries offer the possibilities of low cost and low flammability, together with three-electron-redox properties leading to high capacity 3.

However, research into rechargeable Al batteries over the past 30 years has failed to compete with research in other battery systems.

The low cost and useful electrical properties of aluminium suggest that rechargeable Al-ion batteries could offer viable and safe battery technology, but problems with cathode materials, poor cycling performance and other complications have persisted.
