The lithium battery research activity driven in recent years has benefited the development of sodium-ion batteries. By maintaining a number of similarities with lithium-ion batteries, this type of energy storage has seen particularly rapid progress and promises to be a key advantage in their deployment.
Sodium-ion batteries, much like lithium-ion batteries, are manufactured using similar processes. These batteries use a sodium-based material for the cathode and either carbon or a sodium alloy for the anode. The electrolyte is usually a sodium salt that has been dissolved in an organic solvent.
The working principle of sodium-ion batteries involves electrochemical reactions between sodium ions and electrode materials. While charging, sodium ions migrate from the cathode to the anode; during discharge, they travel in the opposite direction.
Sodium batteries can provide power on demand to ensure a stable and secure energy supply. Reducing carbon emissions from transport is a key pillar of the energy transition. Sodium ion technology is an increasingly real alternative for electric mobility. Sodium-ion batteries can maximise asset utilisation in industry and minimise operating costs.
A typical sodium-ion battery has an energy density of about 150 watt-hours per kilogram at the cell level, he said. Lithium-ion batteries can range from about 180 to nearly 300 watt-hours per kilogram. I asked Srinivasan what he makes of CATL’s claim of a sodium-ion battery with 200 watt-hours per kilogram.
Sodium-ion batteries are ideal for urban Electric Vehicles and grid energy storage due to their resilience and cost-effectiveness. While nickel contributes significantly to energy capacity, efforts are underway to eliminate it for further cost reduction. The goal is to achieve energy density comparable to that in lithium iron phosphate batteries.
