According to POWEROAD's (688345.SH) 2026 semi-annual report (disclosed on August 14, 2026, published on cninfo.com.cn), the company has made staged progress in sodium-ion batteries: it reused its 34145 full-tab large cylindrical cell production process to prepare sodium-ion battery samples, and its polyanionic-system cylindrical cells have completed cell validation — capacity retention of nearly 99% after 1,000 cycles at room temperature, and more than 85% discharge capacity retention even at -40°C, highlighting significant low-temperature performance advantages. On the application side, a UK residential energy storage customer has adopted the company's sodium-ion solution; the product is currently in trial production, with mass production expected within the year.
From a company background perspective, POWEROAD (stock code 688345.SH) is a listed company focused on electric motorcycle batteries and energy storage batteries. In H1 2026, it reported revenue of RMB 1.755 billion, up 30.48% year-on-year, and net profit attributable to shareholders of RMB 72.48 million, up 101.24% year-on-year. During the reporting period, the company simultaneously advanced multiple advanced battery technology directions including semi-solid batteries, all-solid-state batteries and sodium-ion batteries; its all-solid-state battery (dry-process, all-tab sulfide route) has also completed cell validation.
According to the semi-annual report, the sodium-ion cylindrical cells follow the polyanionic technical route and reuse the existing 34145 full-tab large cylindrical production line process; the company also disclosed that "the total storage system cost has basically reached parity with LFP solutions, and with scale-up, cost advantages are expected to be further released."
These statements are company disclosure claims; "cell validation completed" does not equal mass production and delivery, the UK residential storage customer product is still in trial production, and mass production within the year is an expected timeline — actual production and cost levels still carry uncertainty; the "cost parity" is a company self-assessment without third-party audit or volume shipment data support.
