Innovative Sodium-Ion Batteries for Automotive Power Applications

The project aims to develop and demonstrate low-cost 12V batteries for electrified vehicles. These batteries are used for lighting, security, control of the traction battery management system, and other critical features. Generally, in electrified vehicles, these batteries use lead-acid technology due to their low cost and specialized requirements. The consortium seeks to replace these batteries with lower weight and lower volume batteries of comparable cost and performance based on sodium-ion chemistry, a technology that uses more sustainable and lower-cost materials than lithium-ion technology but is otherwise very comparable. The consortium members include Jaguar Land Rover, Croda, Talga Technologies, Faradion Ltd, and Warwick University.

Feedback Overview:

The idea of developing sodium-ion batteries for automotive applications is highly innovative and addresses the need for more sustainable and cost-effective battery solutions. To successfully reach product-market fit, the consortium should focus on rigorous testing and validation of the sodium-ion technology to ensure it meets all safety and performance standards. Additionally, engaging with potential automotive manufacturers early on can help tailor the product to market needs and secure initial adoption.
