New technologies continue to push the boundaries of battery technology. As electrification becomes more prevalent in the heavy-duty and off-highway industries, battery capabilities continue to be a vital link in what new, advanced powertrains are able to accomplish. The Industrial Technology Research Institute (ITRI), Taiwan's largest technology R&D institution, has announced a new material designed to increase cycle life and improve recyclability of lithium batteries.

Over time, the battery discharge/charge process creates microcracks that degrade its performance. ITRI has created ChemSEI-Linker to extend the number of cycles by 70% and increase vehicle range by 15%. This material covers the lithium battery electrodes and protects them from a solid electrolyte interface (SEI) layer that forms on electrodes during the discharge/charge process. Increasing battery life and range could also allow manufacturers the ability to reduce battery pack sizes, lowering an expense that can make up to 40% of a vehicle's cost.
