Sodium battery project environmental impact assessment announcement

Are sodium ion batteries sustainable?

Sodium-ion batteries (NIBs) are key enablers of sustainable energy storage. NIBs use Earth-abundant materials and are technologically viable to replace lithium-ion batteries in the medium term. Na3...

How many cathode designs are there for sodium-ion batteries?

Ten different cathode designs aimed to enhance the energy density, operation lifespan, and rate capability of sodium-ion batteries are selected to provide a representative overview in the sodium-ion battery landscape.

How can the battery industry improve the environment?

The cooperation of the whole battery industry chain, the development of battery materials, the progress of green production and material recycling technology, and the application of new technologies for carbon capture are all essential measures.

How does battery manufacturing affect the environment?

Consequently, the GHG emissions from the battery manufacturing process account for only 2–4 % of the total impacts in both scenarios by 2050. In contrast, the relative contribution from other material flows are likely to increase over time. 3.4.

What is the relative contribution of the battery manufacturing process?

The relative contribution of the battery manufacturing process decreases from 18–32 % to 2–4 % due to the increasingly share of clean energy in the electricity grid, while the relative contribution of key battery component materials increases over time, especially for cathode active materials.

What is the contribution of cathode active materials in battery production?

Cathode active materials were clearly key contributors in all investigated batteries, accounting for a relative contribution of 24–39 % for NMMT, 51–67 % for NVPF, 25–39 % for NaPBA, 51–64 % for NMC 811, and 34–52 % for LFP, regardless of the production year and applied scenarios.
