Dive deep into the core components of a sodium-ion battery and understand how each part plays a crucial role in its functionality. 1. Anode Material: Hard carbon, titanium-based compounds, and antimony-based materials are among the most researched anode materials for SIBs.
The sodium-ion battery, a secondary (rechargeable) battery that works mainly by exchanging sodium ions between the positive and negative poles, works in a similar way to lithium-ion batteries. The sodium salt, which is richer and cheaper than lithium salt, is the main component of the electrode material for sodium-ion batteries.
At the present, the industrialization of sodium ion battery has just started. The choice of material system, the adjustment and improvement of material synthesis and process, the optimization of battery design and manufacturing process, and the product scale effect make the cost of sodium ion battery can be further optimized.
In unison, latest progressions have been done to fabricate many anode materials such as carbon-based materials, alloy-based compounds, MXenes, metal oxides and sulfides and organic compounds. Concurrently, many modifications have been made to enhance the performance and stability of electrode materials in the battery systems.
There are four main components in a battery cell, namely, cathode, anode, separator, and electrolyte. A permeable membrane is present, that is porous and separates the two electrodes and permits only Li + ions while preventing a short circuit caused by direct electrode contact.
Therefore, sodium-ion (Na + ion) batteries (SIBs) have emerged as alternative energy storage system . To fabricate SIBs that meets the demand and sustainability requirements, the components of SIBs should be carefully developed to ensure remarkable performance achievement.
