Effect of Mg2+/Li+ mixed electrolytes on a rechargeable hybrid battery with Li4Ti5O12 cathode and Mg anode†
Abstract
The rechargeable hybrid batteries with a Li+ insertion cathode, Mg anode and mixed Mg2+/Li+ electrolyte could synergistically exploit the advantages of Li+ and magnesium. Herein, we report the electrolyte dependencies on the performance of a hybrid battery containing a commercial Li4Ti5O12 cathode. Additionally, the performance is improved using a graphene based composite.
