Solid state + Li-metal battery
5
Technology Description
Solid state batteries present significant potential for major performance improvements in energy density and thermal stability/safety, in comparison to lithium-ion chemistries, thanks to an inorganic solid electrolyte (current commercial lithium-ion batteries used in electric vehicles use organic liquid electrolytes). The solid electrolyte would also enable the possibility of using lithium metal (Li-metal) as an anode material, which would open prospects for further, major energy density improvements (however the use of Li-metal also poses additional development challenges). Energy densities above 400 Wh/kg at a cell level can be enabled by this technology. Battery reuse (e.g. second-life applications, for instance for energy storage) and/or recycling technologies and policies will be essential to ensure that batteries contribute to sustainability goals.
Relevance for Net Zero
This technology is expected to enter the market in the mid- to late-2020s and eventually enable further performance gains and cost reductions, and to facilitate the electrification of long-range, heavy-duty road vehicles due to its superior energy density. In the longer term, this technology will enable further cost reductions compared to traditional Lithium-ion technology.
