Wanxiang A123 Launches Semi-Solid-State Energy Storage System

On February 7, 2026, Wanxiang A123 Systems Corp. proudly hosted its global launch event at Wanxiang Innovation Energy City, introducing an advanced energy storage solution intended to tackle critical safety challenges in the industry. Under the catchy motto, "Gathering Stars, Smart Storage Future," the company implemented significant changes in energy storage safety measures, moving from reactive fire extinction methods to proactive intrinsic safety features within the system itself.

The centerpiece of the event was the unveiling of the Star Series battery cells and the Star River energy storage solutions. These products mark the world’s first deep integration of semi-solid-state battery technology with immersion cooling systems, setting a new standard for thermal safety and reliability, especially in high-risk applications.

The innovative battery cells in the Star Series utilize proprietary technologies that effectively address issues related to electrolyte leakage and instability. Notably, during a highly publicized puncture test involving 10 sharp needles, a 100 Ah semi-solid battery cell maintained complete stability, showing no signs of fire, explosion, or thermal propagation. This represents an unmatched level of intrinsic safety, far superior to conventional liquid lithium-ion batteries.

At the system level, the Star River Series employs full immersion cooling, ensuring that cell temperature variations remain within just 2°C, even under strenuous operational conditions. This dual-layered protection combines material stability with active thermal insulation, creating a reliable safety barrier against thermal runaway and ensuring dependable functionality in extreme environments.

Beyond safety, the platform offers impressive economic performance, achieving over 10,000 cycles at room temperature and over 7,000 cycles at 45°C. This indicates a remarkable 40% improvement over the industry average. Its exceptional resistance to high temperatures helps to lower the Levelized Cost of Energy (LCOE) by approximately 15%, making it a long-term cost-effective solution for customers.

The Star River Series addresses four major application scenarios. For data centers, the platform features an 800 V HVDC architecture capable of serving as the primary power source. Outdoor cabinet solutions come equipped with IP68 protection to withstand harsh environmental conditions. For offshore applications and logistical constraints, 1.5 m modular containers allow for efficient transport, while 6 m container systems integrate multi-stage fire extinguishing capabilities and a three-tier Battery Management System (BMS) for large-scale deployments.

To further enhance system intelligence, Wanxiang A123 has introduced a wireless BMS + AI platform that uses pressure detection technology. This system can identify risks of thermal runaway an impressive ten minutes before conventional monitoring systems, facilitating predictive safety management and supporting the transition to smart, unmanned energy storage operations.

In conclusion, Wanxiang A123’s latest innovation represents a pivotal advancement in the field of energy storage solutions, combining unprecedented safety features and economic efficiency, and setting a new benchmark for the industry as it moves towards a smarter energy future.
