High energy density ecologically friendly batteries for grid connection of renewable sources and electric vehicles

Abstract

Aqueous Rechargeable lithium batteries (ARLBs) could be an attractive alternative to bypass safety issues of lithium-ion batteries with organic electrolyte. Moreover, the fast lithium diffusion in aqueous electrolyte media could allow for the operations under high electric current conditions required especially for high power supply [1]. In 1994, J. Dahn et al reported a VO2/LiMn2O4 rechargeable aqueous battery [2]. However, this type of batteries had serious issues with cyclability. In this work, we report for the first time on a system comprising in an aqueous electrolyte, and on large-scale ARLB based on this concept with enhanced cycle performance and energy density.
