Energy storage systems come in many forms, leveraging different technology types. A class of electrochemical storage, lithium-ion batteries have established themselves as the industry standard.
But there are many new technologies vying for their market share.
Sodium-ion batteries are widely considered a sustainable and resource-saving answer to future energy storage, while flow batteries offer a viable alternative in long-duration storage applications.
However, the path to commercialization is not a straightforward one.

Sodium-ion batteries now competitive in niche markets
Sodium‑ion batteries are emerging as a safer, lower-cost alternative to lithium‑ion, with a recent international study highlighting their competitiveness in stationary energy storage. The research shows that ongoing investment and supply-chain development could enable broader adoption within the next decade.
Scientists design low-cost sodium-ion battery with cheap electrode materials
Conceived for stationary energy storage, the proposed sodium-ion battery configuration relies on an P2-type cathode material and an hard carbon anode material that reportedly ensure full-cell performance. Electrochemical testing revealed initial capacities of 200 mAh/g for the cathode and 360 mAh/g for the anode with capacity retentions of 42% and 67.4% after 100 cycles.
