China-based Narada has announced the launch of its latest breakthrough, the 783Ah ultra-high capacity solid-state energy storage battery. Building on its earlier success with a 30Ah model, the new battery represents a significant leap in both energy density and safety for large-scale energy storage systems.
Narada’s R&D team achieved this advancement through three core technological innovations: a flexible biphasic oxide solid electrolyte, a multi-layer heterogeneous composite structure, and in-situ electrolyte film formation technology. These solutions address common challenges in solid-state batteries, such as electrolyte brittleness and poor electrode-electrolyte contact.
The flexible biphasic oxide solid electrolyte offers high ionic conductivity (10⁻³ S/cm) and enhanced mechanical strength, significantly reducing cracking risks. Meanwhile, the in-situ film formation technology enables the electrolyte to self-assemble into a thin, flexible layer around electrode particles, dramatically lowering interfacial resistance and boosting cycling stability.
The 783Ah battery also features a multi-layer structure, combining a LiCon functional layer and a SIL interfacial layer, enabling fast ion transport and improving mechanical strength.
Key specifications include:
- Cycle life: over 10,000 cycles
- Single-cell energy: more than 2.5 kWh
- Energy efficiency: above 95%
- Volume energy density: greater than 430 Wh/L
Thanks to the inherent safety advantages of solid-state designs—such as no liquid leakage or fire risk—the 783Ah battery is well-suited for critical large-scale storage applications.
With this innovation, Narada is positioning itself to accelerate the commercial rollout of ultra-safe, high-performance solid-state batteries, playing a key role in the future of energy storage.
