With the current state of product and production technology, the electricity demand of all battery factories planned worldwide in 2040 will be 130,000 GWh per year, equivalent to the current electricity consumption of Norway or Sweden - this is the conclusion of a study by the research team led by Dr. Florian Degen of the Fraunhofer Research Institution for Battery Cell Production FFB, the MEET of the University of Münster, the Helmholtz Institute Münster and the University of Münster.

How much energy does a battery use?
Production scale and battery chemistry determine the energy use of battery production. Energy use of battery Gigafactories falls within 30–50 kW h per kW h cell. Bottom-up energy consumption studies now tend to converge with real-world data.
All other steps consumed less than 2 kWh/kWh of battery cell capacity. The total amount of energy consumed during battery cell production was 41.48 kWh/kWh of battery cell capacity produced. Of this demand, 52% (21.38 kWh/kWh of battery cell capacity) was required as natural gas for drying and the drying rooms.
What is the energy consumption involved in industrial-scale manufacturing of lithium-ion batteries?
The energy consumption involved in industrial-scale manufacturing of lithium-ion batteries is a critical area of research. The substantial energy inputs, encompassing both power demand and energy consumption, are pivotal factors in establishing mass production facilities for battery manufacturing.
Nature Energy 8, 1180–1181 (2023) Cite this article Lithium-ion battery manufacturing is energy-intensive, raising concerns about energy consumption and greenhouse gas emissions amid surging global demand.
However, new product and production technologies can optimize battery cell production to achieve savings of up to 66 percent, equivalent to the energy consumption of Belgium or Finland (in 2021). These groundbreaking results have now been published in the world-renowned journal “Nature Energy”.
As additional large-scale battery factories are taken into use, more data should become available, and the reliance on outdated, unrepresentative, and often incomparable, estimates of energy usage in the emerging Li-ion battery industry should be avoided.
