AZTEQUE - Zinc-air battery for electric transport
Overview
Background & policy context:
The electric vehicle needs to ensure its success, a low-cost, high energy density, safe, recyclable battery with no negative impact on the environment. The electrically rechargeable zinc-air battery is one of the only ones able to meet these specifications. Its outcome would provide a credible alternative to lithium-ion battery essential to limit risk for the development of EVs.
Objectives:
Project AZTEQUE aims to develop an electrically rechargeable zinc-air battery, able to operate with ambient air without decarbonation treatment. The AZTEQUE battery will also be able to meet specific power calls through internal hybridization performed with a third power electrode. This hybridization also improves energy efficiency by cycling. This technology has the advantage of having a low cost (potentially close to the lead battery), to present a high specific energy, using only abundant materials (zinc, potassium, carbon), to operate in the middle aqueous, non-toxic nor flammable (no organic solvent) with all the necessary safety guarantees.
