Foreign media report (GlobeNewswire official press release; CBAK Energy Technology, NASDAQ: CBAT): On September 17, the Dalian-headquartered company - the first Chinese lithium battery manufacturer listed on Nasdaq in January 2006 - reported internal test results for its 32140 NH-7Ah full-tab cylindrical sodium-ion cell and outlined a long-term plan for 12 GWh of annual sodium-ion battery production capacity. The cell targets energy storage, light electric mobility and selected backup power applications, using an NFPP (sodium iron phosphate pyrophosphate) polyanion cathode combined with a full-tab design for high-current operation and heat dissipation.
On test data: under specified internal protocols, the cell reached 90% SOC within 15 minutes; capacity retention stayed above 95% during continuous 15C discharge, with 28C pulse discharge support; discharge capacity retention at -40°C was 87.68% relative to the 25°C baseline; under a 1C/1C cycling protocol at 70°C, trend analysis supports a projected cycle life of roughly 3,500 cycles to 80% retention; and based on internal cycle-life testing and trend analysis, the cell is projected to deliver at least 10,000 cycles under the specified protocols.
On safety, internal nail-penetration samples showed a high pass rate, and testing supported storage and transportation at 0% SOC. Customer sample testing is underway in residential and portable energy storage and electric two- and three-wheelers, with additional evaluations covering specialty vehicles, start-stop systems and backup power. On capacity: the planned 12 GWh of lines would be designed for compatibility with lithium-ion cell production; future plans cover larger 46- and 60-series cylindrical formats and specialized high-rate cells for AI data center backup power.
All performance figures are internal laboratory results; cycle life figures are projections based on trend analysis; the 12 GWh figure is a conditional planning objective and does not represent installed capacity, with deployment subject to customer qualification, commercial demand and implementation requirements; 'industry-first scaled sodium-ion production' is the company's own claim.
