![]() This makes the production of sodium-ion batteries more cost-effective than lithium-ion batteries, which rely on scarcer and more expensive lithium. The economic appeal of sodium-ion batteries lies in the fact that sodium is both abundant and cheap. However, researchers from Cornell University have discovered key aspects of the mechanism behind this phase transition and propose modifying the battery chemistry to introduce strategic disorder to the particles before the flawed transition phase, potentially reducing the ordering effect observed. This leads to disorder in the crystal structures and eventual battery failure. This is mainly due to a specific atomic reshuffling during the battery’s operation, known as the P2-O2 phase transition. ![]() One of the main challenges with sodium-ion batteries is the issue of poor durability, particularly when compared to lithium-ion batteries. We visited the opening of their new production facility. The materials required for SIBs, such as sodium, do not suffer from the same geographical distribution issues and environmental concerns as lithium, cobalt, copper, and nickel commonly used in LIBs.ĪQUABATTERY’s battery technology can safely store energy using water and table salt. SIBs are therefore often referred to as salt batteries.Ĭompared to LIBs, SIBs offer potential advantages due to the lower cost and more widespread availability of sodium compared to lithium. However, SIBs replace lithium with sodium as the cathode material, taking advantage of sodium’s abundance in nature. Similar to lithium-ion batteries (LIBs), SIBs have a cathode, an anode, and a liquid electrolyte. Sodium-ion batteries (SIBs) are rechargeable batteries that use sodium ions (Na+) as the charge carriers.
