Munich, Germany | May 7-9, 2025 — Highstar debuted the world’s first semi-solid battery and system-level solutions at The Smarter E Europe 2025. On the second day of the exhibition, the company hosted a technical launch event themed “Ultimate Safety Beyond Limits”, where its groundbreaking hybrid solid-liquid electrolyte technology redefined the safety boundaries of energy storage, positioning Highstar as a focal point in Europe’s energy sector.

Technological Breakthrough: Dual Advancements in Safety and Performance

Highstar’s new Semi-Solid Battery series delivers multi-dimensional upgrades through its hybrid electrolyte technology:

Safety Benchmark: Thermal runaway trigger time delayed by over 40%, trigger temperature increased by 30°C+, and module safety performance improved by 20%+ compared to liquid batteries. The world’s first 314Ah Semi-Solid Battery passed a rigorous 5mm nail penetration test, achieving "zero thermal runaway" with no fire or explosion under extreme conditions.

Longevity & Efficiency: Cycle life reaches 7,000 cycles @80% SOH, with charge-discharge efficiency exceeding 95%, ideal for high-energy-density applications.

Intelligent Manufacturing: Fully automated production lines and 3,000+ quality control points ensure cell consistency, achieving a 99.8% yield rate.

Scenario Empowerment: Multi-Scenario Solutions for Europe’s Carbon Neutrality

Highstar focuses on five core application scenarios with tailored solutions:

Grid Energy Storage: Nano-oxide electrolyte technology enhances thermal stability by 30%, paired with the 314Ah Semi-Solid Battery for "zero thermal runaway" in extreme environments.

Commercial & Industrial Energy Storage: The 20-ft containerized energy storage system supports high-power demands, operates across a wide temperature range (-30°C to 60°C), and reduces lifecycle energy costs by 20%.

Marine Power: High-Rate Modules: Peak power increased by 40%, meeting instant power demands for hybrid vessels; High-Energy Modules: Range extended by 25%, enabling long-duration operations for all-electric ships.

Residential & Balcony PV Storage: Modular design with cloud-based management, 7,000 cycles @80% SOH, and 95%+ efficiency ensure safety and cost-effectiveness.

Telecom Backup Power: IP67-certified systems operate stably in harsh conditions, reducing failure rates by 50% and ensuring 24/7 power supply.

Exhibition Highlights: Surging Interest in Semi-Solid and Sodium-Ion Technologies

Daily booth traffic exceeded 300 visitors, with strong interest in sodium-ion energy storage systems. Highstar’s NFPP sodium-ion solutions for commercial and industrial storage have been deployed across China, praised for their wide temperature adaptability (-30°C to 60°C) and rapid charge-discharge capabilities. The 20-ft sodium-ion container system, recognized for its adaptability and cost-efficiency, has secured purchase intent from European clients, accelerating energy transition in grid and residential applications.

Global Strategy: Pioneering a Sustainable Future

With 30 years of R&D expertise, Highstar operates a 16GWh annual global capacity, covering the entire value chain from materials to system integration. The company will deepen its localization strategy in Europe, collaborating with regional partners to advance high-safety, high-efficiency energy storage technologies, supporting Europe’s 2050 carbon neutrality goals and delivering "China’s Solutions" for global energy transformation.
