Aluminium-Air Batteries for EVs

Hindalco Industries signed an agreement with Israel-based Phinergy and IOC Phinergy Private (IOP). The companies will work exclusively on R&D and pilot production of aluminium plates for Aluminum-Air batteries.

• The trio will also look into recycling of aluminum after usage in these batteries.

• India has an abundance of aluminum resources and this technology can help enhance the nation’s energy and resource security.

Salient features

• Aluminum-Air technology enables energy generation by combining oxygen from ambient air with metals, specifically aluminum and zinc.

• Aluminum-Air batteries offer a viable alternative to other battery chemistries and will boost the domestic manufacturing of batteries to meet India’s growing demand for energy storage.

• In the Aluminium-Air battery, developed by Phinergy, energy is released when aluminium reacts with oxygen in ambient air to produce aluminium hydroxide.

• Due to its light weight and high energy density, an Aluminium-Air battery significantly increases the driving range of Electric Vehicles.

• It also enables quick ‘refuelling’ and eliminates the need for expensive nationwide charging networks.

• Aluminium-air batteries are expected to make EV adoption more convenient, and accelerate the transition to zero emission mobility.

• An added benefit is that aluminium hydroxide in the battery can be recycled to recover aluminium.
