Wanxiang A123 Unveils World's First Semi-Solid Immersive Energy Storage System, Setting Safety Standards

Introduction

On February 8, 2026, Wanxiang A123 Systems Corp. unveiled a groundbreaking energy storage system at an international launch event held at Wanxiang Innovation Energy City. The event was themed "Gathering Stars, Smart Storage Future," marking a transformative leap in energy storage safety from reactive fire suppression to intrinsic prevention mechanisms.

Key Innovations

Star Series Battery Cells

A cornerstone of this new platform is the introduction of the Star Series semi-solid battery cells. These cells leverage proprietary technology to fundamentally address issues related to electrolyte leakage and instability. One of the most compelling demonstrations involved puncturing a 100 Ah semi-solid battery cell with 10 needles; impressively, it maintained stability without presenting any fire, explosion, or thermal runaway—something that conventional liquid lithium-ion batteries cannot achieve.

Star River Series Energy Solutions

The Star River Series introduces an innovative immersion cooling technology that keeps temperature variation in battery cells to less than 2 °C, even under demanding operating conditions. This dual-layer protective system effectively combines material stability with active thermal insulation, creating a robust barrier against thermal runaway and ensuring reliable operation in extreme environments.

Economic Advantages

Beyond safety, the Star River platform offers remarkable economic benefits. The system boasts over 10,000 cycles at room temperature and more than 7,000 cycles at 45 °C, reflecting a 40% improvement over industry averages. Its outstanding resistance to high temperatures aids in lowering the levelized cost of energy (LCOE) by approximately 15%, presenting clients with a cost-effective long-term solution.

Application Scenarios

The Star River Series includes solutions tailored for four primary application scenarios:
1. Data Centers: Utilizing an 800 V HVDC architecture, this platform can serve as a main power source.
2. Outdoor Cabinets: Designed with an IP68 protection rating, these solutions are built to withstand harsh environmental conditions.
3. Offshore Applications: Modular 5-foot containers allow for efficient shipping and deployment, while 20-foot container systems incorporate multi-level fire suppression and triple-level BMS protection for large-scale deployments.
4. Smart Energy Management: A wireless BMS platform integrated with AI offers advanced pressure detection technology, identifying thermal runaway risks up to 10 minutes earlier than traditional monitoring systems. This predictive safety management supports the evolution towards smart, automated energy storage operations.

Conclusion

With these innovations, Wanxiang A123 is not only setting new benchmarks for safety and operational efficiency but is also poised to revolutionize the energy storage landscape. Stakeholders in various sectors can look forward to enhanced reliability and cost savings, making the transition to advanced energy storage technologies a feasible and attractive option for the future.
