Solid-state batteries can reduce the carbon footprint of electric cars by 39%, according to a new report authorized by the environmental advocacy group Transport & Environment (T&E).
Compiled by Minviro, a company that performs raw materials lifecycle analysis, the report compares the overall carbon emissions of solid-state batteries with two of the most popular lithium-ion chemical plants currently available. today: nickel-manganese-cobalt (NMC) and lithium iron phosphate (LFP).
The analysis found that solid-state batteries were reduced overall by 24% based on technology alone and 39% if sustainable materials were used. It should also be noted that LFP batteries have a slightly higher carbon footprint according to these calculations.
Solid Power Battery
The report says solid-state batteries can use 35% more lithium than current lithium-ion chemical plants, but far less than graphite and cobalt. T&E also hopes new mining methods, such as extracting lithium from geothermal wells, will work and reduce the environmental impact of lithium sourcing.
Solid-state batteries, which get their name from the solid electrolyte used as an alternative to liquid in lithium-ion chemical plants today, are primarily advertised for their energy density. Some automakers—Nissan is a—It has been suggested that solid-state technology could help create some electric pickups and SUVs.
While a number of automakers, battery suppliers, and startups are investing in the technology, solid-state batteries won’t be ready for commercial use until the end of the decade at the earliest. this.
Nissan produces prototype solid-state cells
Toyota and Panasonic currently leads in patents, according to a recent report. And with Toyota’s goal of bringing technology become a hybrid firstSuch a model that is making the most of its battery could have the lowest CO2 in the battery of any electric vehicle.
Despite the buzz surrounding solid-state batteries, it’s worth noting that the technology has yet to be proven in production vehicles. Will lifetime of solid state cells be longer? That’s an important question that needs to be answered in real-world usage.
