Sodium-ion batteries (NIBs, SIBs, or Na-ion batteries) are several types of rechargeable batteries, which use sodium ions (Na +) as their charge carriers. In some cases, its working principle and cell construction are similar to those of lithium-ion battery (LIB) types, but it replaces lithium with sodium as the intercalating ion.
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.
Some sodium titanate phases such as Na 2 Ti 3 O 7, or NaTiO 2, delivered capacities around 90–180 mAh/g at low working potentials (< 1 V vs Na/Na +), though cycling stability was limited to a few hundred cycles. In 2021, researchers from China tried layered structure MoS2 as a new type of anode for sodium-ion batteries.
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 are composed of the following elements: a negative electrode or anode from which electrons are released and a positive electrode or cathode that receives them.
It accounts for roughly half of the capacity and a flat potential profile (a potential plateau) below ⁓0.15 V vs Na/Na +. Such capacities are comparable to 300–360 mAh/g of graphite anodes in lithium-ion batteries. The first sodium-ion cell using hard carbon was demonstrated in 2003 and showed a 3.7 V average voltage during discharge.
