Materials researchers of the Paul Scherrer Institute PSI in Switzerland have, in collaboration with the Université Grenoble Alpes (France), developed a simple method that can improve the performance of lithium-sulfur batteries by 25-30%. For example, the lithium-sulfur battery rapidly loses capacity with repeated charging.

Lithium-sulfur batteries are of great interest for electromobility applications, among others, due to their high specific energy and relatively low cost, but are challenged by significant capacity decay over cycling. In the lithium-sulfur model, the cathode is composed of elemental sulfur. Earlier post.)

Ricardo has developed a new Battery Management System (BMS) for EVs that is scalable to a wide range of applications. This can represent a very significant cost element of a typical battery electric vehicle (BEV); manufacturers need to strike a balance between product affordability and available range between recharges.

Researchers at Rensselaer have developed a new technique using heat to enable self-healing lithium-metal anodes to eliminate dangerous dendrite buildup, paving the way for higher energy density battery technologies. We have found that lithium metal dendrites can be healed in situ by the self-heating of the dendritic particles.

As she drives her electric vehicle to her mother’s house, Monique’s battery gauge indicates that it’s time to reenergize. The battery in her EV is a variation on the flow battery , a design in which spent electrolyte is replaced rather than recharged. A battery that mitigates these problems is DARPA’s objective.
