HiNa Battery scales Korean sodium-ion partnership from 15 MWh to 10 GWh

Sodium-ion batteries are gaining attention because they can reduce reliance on lithium-based supply chains, even though LFP remains the dominant chemistry for stationary storage. A 10 GWh supply agreement gives HiNa and Volta a platform to test sodium-ion economics at grid and commercial scale in Korea. For solar and storage developers, the partnership is worth tracking because chemistry diversity could affect future project costs, safety profiles, and supply security.
