Solvent Mixture: A solvent mixture is an electrolyte solvent that enables high ionic conductivity and has a wide operating temperature range.Īl Current Collector: Aluminum foil acts as a suitable current collector because it provides high electrical conductivity and stability.īinder: Binder materials prevent electrode swelling and hold active material particles within an electrode together. It facilitates ion transport and averts contact between the anode and cathode. Separator: A separator is a polymer-based membrane that is porous and acts as an electrical insulator to prevent an internal short circuit. It acts as an electron donor.Įlectrolyte: It is the ionic medium for current transfer. It acts as an electron acceptor.Ĭathode: A cathode is where reduction takes place during the discharge process. Ion: An ion is an atom or a group of items with a net electric charge due to the gain or loss of electrons.Įlectrode: An electric conductor that carries electric current and is vital to producing a battery’s electric charge.Īnode: An anode is where oxidation takes place during the discharge process. Its symbol is derived from the Latin name, Natrium. Sodium: Sodium (Na) is a highly reactive, soft, silvery-white chemical element with an atomic number 11. Before diving deep into the working principle of a sodium-ion battery, it is good to know some key terms related to the sodium-ion battery.īattery: A battery is a device that converts chemical energy into electricity/electrical energy. Now, we will see the components of a sodium-ion battery.Ī sodium-ion battery is a powerhouse of performance that optimizes a sodium-ion cell for electric output. Sodium-ion batteries score well on the above parameters except for energy density that needs augmentation to compete on par with lithium-ion batteries. The main factors that determine battery efficacy include: Is it difficult to find the best compromise between sustainability and maximization of battery performance? It is not difficult but doable. As batteries are ubiquitous in our lives, they need to provide value for money-consistently and cost-effectively. The alkali metal is well known for its versatile uses.Īlthough the history of sodium-ion batteries goes back to the 1980s, lithium-ion batteries took center stage in the 1990s due to their high energy density that proved successful for energy storage needs.Ī decade ago, the focus shifted to sodium-ion batteries because of an alarming awareness of dwindling lithium supplies globally. In 1807, Sir Humphry Davy-an English chemist and inventor-discovered sodium by the electrolysis of sodium hydroxide. History and Background of Sodium-Ion Batteries The Future Roadmap for Sodium-Ion Batteries.

History and Background of Sodium-Ion Batteries.

Let us get to know the ins and outs of sodium-ion batteries and, of course, the future roadmap. The sodium-ion battery is slowly but steadily gaining a competitive edge in the global battery market. However, the relative abundance and low cost of sodium position it as a popular choice for next-generation battery technologies. Lithium-ion batteries (LIBs) may not cater to the future demand for cost-effective and sustainable energy storage. While the lithium market is showing a supply deficit in relation to demand, the sodium market looks promising with a balanced level of demand and supply. When it comes to the quest for sustainable post-lithium batteries, research shows a promising alternative in sodium-ion batteries (SIBs).

The scarcity of lithium supplies is the driving factor behind the growing need to tap into alternative battery systems for large-scale energy storage. The modern economy is pushing the demand for affordable and eco-friendly energy sources. It is the humble sodium that is accelerating the energy transformation worldwide. The energy storage conversation is buzzing with sodium-ion technology, and rightly so.
