Title: Strategies targeting 5V Li-ion batteries
Affiliation: SINTEF

Abstract

Key stumbling blocks for developing 5V Li-ion batteries is the flammable electrolyte, that can result in thermal runaway and the predicted shift from cobalt electrodes which will require new electrolyte blends or cathode surfaces to be passivated.  “Dry” cells with all solid electrolytes must be the ultimate objective in terms of safety. Moreover, solid electrolytes that are impenetrable to Li metal dendrites will enable the use of Li anodes and hence increase the energy density. Building on SINTEF’s experience in Li-ion electrodes, polymer science and function oxides, secondary batteries have become a core research area. Work presented here will detail three approaches under investigation at SINTEF for resolving the safety and stability issues of the existing Li-ion batteries: 1) Highly stable, liquid electrolyte formulations for current Li-ion battery manufacturing processes. 2) Solid-state polymer electrolytes (SPE). 3) Solid-state composite polymer-ceramic electrolytes.
