Battery Technology

Rechargeable battery technology is advancing rapidly. Cutting-edge chemistries and constructions such as sodium-ion, solid-state lithium metal, and lithium-ion with silicon anode promise to overtake the performance of lithium-ion batteries soon. The following table compares lithium-ion technology (as baseline) with these emerging technologies, highlighting the pros and cons of each.

“A sodium-ion battery is a rechargeable energy storage technology that uses the flow of sodium ions (Na+) between the anode and cathode during the charging and discharging processes. Although the active materials are different, its mechanism is comparable to that of a lithium-ion battery” [Puteri]. Sodium-ion batteries are chemically stable and have a simplified supply chain. They have excellent cycle life and fewer thermal-runaway concerns than lithium-ion batteries. Sodium-

The “silicon (Si)-based anode has emerged as the most promising anode material for next-generation lithium-ion batteries (LIBs) due to its high specific capacity, suitable operating potential and abundant natural reserves” [Zhao]. These batteries are seen as a bridge between conventional lithium-ion and future technologies (e.g., solid-state). They allow fast charge times, have decent cycle life, and exhibit great energy density. Silicon is also non-toxic and abundantly avail

Solid-state batteries are getting a lot of publicity because of their remarkable performance potential over existing battery technologies. According to Shimabukuro, “solid-state batteries represent a major advancement in energy storage technology because they replace the liquid or gel electrolytes in traditional lithium-ion batteries with solid materials (like ceramics or polymers).” This allows them to be non-flammable and thermally stable. They can charge incredibly quickly
