On April 7, 2026, Shenzhen Jiana Energy Technology Co., Ltd. announced the successful closing of a Series A+ financing round totaling several hundred million yuan. The round was led by Shenzhen Energy Storage Fund and EVE Energy Co., Ltd. (300014), a major player in the lithium battery industry.
The capital will be deployed to accelerate technological iteration of key sodium-ion battery materials, expand production capacity, and drive global market penetration. Jiana Energy specializes in polyanionic cathode and biomass hard carbon anode technologies, holding over 300 patents. The company has already commissioned the world's first万吨-level production line for polyanionic cathode materials, with cumulative deliveries reaching thousands of tons and contractual orders exceeding ten thousand tons.
This development signals strong investor confidence in sodium-ion technology as a viable, cost-effective alternative for large-scale energy storage applications, particularly as the industry seeks to diversify from lithium-based supply chains. Jiana's customer base includes industry leaders such as BYD, CATL, and Hithium Energy Storage.
For B2B stakeholders, this means reduced reliance on lithium, improved supply chain resilience, and access to proven sodium-ion solutions for grid-scale and industrial energy storage projects.
