Solid state batteries can further boost climate benefits of EVs – study
(Transport and Environment, 19 Jul 2022) The new technology could reduce the carbon footprint of an electric car battery by up to 39%.
Solid state batteries can reduce the carbon footprint of electric vehicle batteries by almost two-fifths – further increasing EVs’ advantage over fossil fuel vehicles. That’s according to research commissioned by Transport & Environment (T&E) from Minviro, a company specialised in raw material life-cycle analysis, which compared emerging solid state technology to current battery chemistries.
A solid state battery, which stores more energy with less materials, can reduce the already decreasing carbon footprint of an electric car battery by a further 24%, the study finds. The analysis compares a NMC-811 solid state battery, which is one of the most promising chemistries being developed, to current lithium-ion technology. Solid state technology uses solid ceramic material instead of liquid electrolytes to carry electric current, also making the batteries lighter, faster to charge and eventually cheaper. Battery manufacturers forecast that solid state batteries will be used in EVs in the second half of the decade.
Cecilia Mattea, clean vehicles officer at T&E, said: “Electric vehicles are already far better for the planet than burning oil and the carbon footprint of batteries is falling every year. But solid state technology is a step change because their higher energy density means far less materials, and therefore far less emissions, are needed to make them.”
