Increased battery production would significantly reduce carbon emissions
A common criticism of electric vehicle production is the high carbon emissions from battery production. A Swedish study (Chalmers University) states that increasing production capacity
in gigafactories would significantly reduce the environmental impact.
If the energy used to power the factories comes from green sources, emissions can be reduced by about a quarter compared to the results reported a few years ago.
The Swedes claim that increased production in huge factories leads to significant reductions in energy consumption per kWh of battery storage capacity produced. By up to 58%.
If energy is supplied from low-carbon sources, emissions are reduced by a further 55%.
The researchers say that with large-scale production, a greater proportion of the impacts move further up the supply chain, to the extraction and processing phases of the raw materials.

Editor's note The article states but does not substantiate its claims. It does not describe how the environmental impact can be reduced. It is not enough to say that green energy supply reduces emissions. We do not understand how emissions can be halved by switching to a different scale of production, because the individual requirement per battery remains the same. There is only a shortening of the intervals between the production of each battery. At no point is it indicated that a change in technology would change the industrial approach to production.
