Highstar's Revolutionary Semi-Solid Battery
From May 7 to 9, 2025, the city of Munich, Germany, played host to one of the most innovative showcases in the energy sector at The Smarter E Europe 2025. Highstar, a well-established player in battery technology, showcased its groundbreaking semi-solid battery solutions, redefining safety norms within the industry. The event attracted over 300 daily visitors eager to explore Highstar's advancements that aim to ensure safer energy storage systems.
A New Era of Safety
The heart of Highstar's presentation was centered around the theme "Ultimate Safety Beyond Limits". During a technical launch on May 8, Highstar revealed details about their revolutionary electrolyte technology, which is a hybrid of solid and liquid. This innovative design extends the thermal runaway trigger time by more than 40%, while also raising the critical temperature threshold by 30°C compared to traditional liquid-based batteries. Notably, Highstar's semi-solid battery, with a capacity of 314Ah, became the first of its kind to successfully withstand a 5mm nail penetration test, achieving zero thermal runaway and demonstrating its non-flammable and non-explosive properties even under extreme conditions.
Unmatched Performance
The benefits don’t stop at safety. This new battery design offers impressive performance metrics, boasting up to 7,000 cycles while maintaining an 80% State of Health (SOH) and an energy efficiency exceeding 95%. Highstar’s state-of-the-art manufacturing processes include over 3,000 quality control checkpoints and an entirely automated production line, assuring uniformity across battery cells with a remarkable yield rate of 99.8%.
