New battery system developed for intermediate storage of renewables

Researchers at the MEET Battery Research Centre at Münster University have developed a new energy storage system based on dual-ion battery technology. Its long service life is promising for stationary applications. The focus of the development was on cost-effective battery systems. The key difference to lithium-ion batteries is the purpose of the electrolyte. Chemist Dr. Tobias Placke from MEET explains further that, “In the lithium cell, it serves only as a transport medium for lithium ions between both electrolytes. In the dual-ion cell, however, it is an active material.”
