The global sodium-ion battery market is poised for explosive growth, with projections indicating a fourfold increase to $1.2 billion by 2031, according to a recent report by Allied Market Research. Driven by surging demand from electric vehicles (EVs), stationary energy storage systems, and a global push for affordable clean energy, sodium-ion technology is quickly gaining traction as a viable alternative to lithium-ion batteries.
Valued at $0.3 billion in 2021, the sodium-ion battery sector is expected to grow at a compound annual growth rate (CAGR) of 15.9% from 2022 to 2031. The technology’s appeal lies in its use of widely available raw materials, lower production costs, and superior thermal stability compared to its lithium-ion counterpart.
What Sets Sodium-Ion Batteries Apart?
Unlike lithium-ion batteries, sodium-ion variants operate by de-intercalating sodium ions from the cathode to the anode during charging. While they offer slightly lower energy density, their cost-efficiency, fire safety, and ease of raw material sourcing make them an attractive choice for multiple industries.
Europe Leading the Charge
Europe currently dominates the sodium-ion battery market, propelled by strict carbon emission regulations and an aggressive transition to green energy. Increased investment in renewable storage technologies and cost-effective battery manufacturing are further accelerating adoption in the region.
