The active functional separator is Ruizhi's core mass‑produced product. It employs the company's independently developed functional coating material powders, applied onto PP/PE base films via roll‑coating, spray‑coating, and other processes. Compared with traditional inorganic (alumina, boehmite) or organic (PVDF, aramid) coating materials, this product constructs a more three‑dimensional lithium‑ion conduction pathway through semi‑solid hybrid electrolyte technology, significantly enhancing cell safety, thermal resistance, and rate capability. Featuring three key attributes – high safety, high rate capability, and high thermal resistance – it is widely applicable in liquid and semi‑solid hybrid battery systems. The first‑generation active functional separator has already achieved stable mass production and can be broadly used in power batteries, energy storage systems, and consumer electronics.

2.2 Second‑Generation Product: Quasi‑/All‑Solid‑State Electrolyte Membrane
To meet the development needs of next‑generation solid‑state batteries, Ruizhi has independently developed the SCS ion‑conductor quasi‑/all‑solid‑state electrolyte membrane. This product, combined with self‑supporting substrate materials, forms a membrane‑form quasi‑/all‑solid‑state electrolyte that can be applied in next‑generation solid‑state cell systems, dramatically enhancing energy density and safety. It provides reliable support for high energy density, high safety, and long cycle life. Currently, significant breakthroughs have been achieved in the R&D of the second‑generation quasi‑/all‑solid‑state electrolyte membrane at high‑energy‑density cell scales, with key performance indicators reaching industry‑leading levels. The product has completed testing and certification by multiple leading battery companies and meets the stringent GB38031 standards.

SMM Perspective

Ruizhi New Energy's Pre‑A+ financing round marks its transition from local incubation under the Qinchuangyuan programme to a new phase with strategic state‑capital support from the Yangtze River Delta. Leveraging its technology transfer background from Northwestern Polytechnical University, the company has used its "active functional separator" to enter the supply chains of top battery manufacturers and achieve scaled deliveries, while simultaneously positioning its "membrane‑form solid‑state electrolyte" as a key material for next‑generation all‑solid‑state batteries. This has created a clear product roadmap of "mature generation, developing generation, and pre‑research generation". The dual‑track approach – advancing both the membrane‑form solid‑state electrolyte thermal composite technology and the active functional separator – balances short‑term commercial monetisation with long‑term technological moat building. However, from an industry competition perspective, the solid‑state electrolyte membrane space features diverse technology routes and dense deployment by both domestic and international players. Ruizhi's current scale remains relatively small, and the construction of its Yixing base and subsequent capacity ramp‑up will be critical tests. Overall, the company has a precise positioning and a clear path forward; whether it can sustain the balance between scaled delivery and continuous technological iteration deserves close monitoring.

Finally, we recommend SMM's premium conferences. Current progress and some participating companies and representatives are as follows:

This week (July 31 – August 6, 2026) saw a triple convergence of technological validation, capacity deployment, and capital influx in the solid-state battery industry. Zhongke Yuanben completed China's first on‑road vehicle test of a sulfide‑based all‑solid‑state battery, validating full‑stack technology integration.
