Rept Battero has unveiled its Wending 320 Ah sodium-ion energy storage cell at SNEC 2026 in Shanghai, targeting utility-scale, long-duration energy storage projects and applications in extreme climates.
The Chinese battery manufacturer launched the product alongside an 85 Ah high-power lithium iron phosphate (LFP) cell designed for AI data center energy storage. The Wending 320 Ah sodium-ion cell is aimed at power-generation and grid-scale storage projects, as well as large commercial and industrial (C&I) applications requiring long service life and wide operating-temperature ranges.
Rept Battero said the cell has a rated capacity of 320 Ah, a cycle life of more than 20,000 cycles, round-trip efficiency of at least 97%, and an operating temperature range of -50 C to 60 C. The company also claims a service life of 25 to 30 years, aligning the product with the expected operating life of many utility-scale energy storage assets.
