A single electric car lithium-ion battery pack "could contain around 8 kg of lithium, 35 kg of nickel, 20 kg of manganese and 14 kg of cobalt," according to Nature.
As a result, building the 80 kWh lithium-ion battery found in a Tesla Model 3 creates between 2.5 and 16 metric tons of CO 2 (exactly how much depends greatly on what energy source is used to do the heating). 1 This intensive battery manufacturing means that building a new EV can produce around 80% more emissions than building a comparable gas ...
In brief MIT combustion experts have designed a system that uses flames to produce materials for cathodes of lithium-ion batteries—materials that now contribute to both the high cost and the high performance of those batteries. Based on extensive lab-scale experiments, the researchers'' system promises to be simpler, much quicker, and far less …
