Solid state batteries will cut carbon footprint of EVs by a quarter
Daily MailOne of the biggest criticisms of electric cars is that they're not as green as you might think, with claims it takes years of driving one to offset the high emissions resulting from battery production. However, a new report says electric vehicles will become more economical in the future when manufacturers switch to using solid state batteries, claiming they will reduce EV carbon footprint by almost a quarter. Electric cars could become much greener before the end of the decade: New report claims models using solid state batteries will cut production-related emissions by a quarter Greenhouse gas emissions during production of an electric vehicles are far higher than an equivalent petrol model, which is mainly due to the carbon intensity of battery and steel production. These batteries require up to 35 per cent more lithium than the current lithium-ion technology fitted in most of today's electric cars, but far less graphite and cobalt is needed for solid state packs. Transport & Environment's study estimates that a solid state battery made of sustainably-sourced materials will reduce the carbon footprint compared to today's EVs by up to 39% EV battery experts estimate it takes between 13,500 and 16,000 miles of driving - equivalent to two years of UK ownership - for the extra carbon footprint of EV production to be offset T&E's report says they will reduce the production carbon footprint of electric cars by of an estimated 24 per cent.
