Blade Technology

The blade battery is an innovative structural design of Lithium Iron Phosphate battery, where the battery cells are designed to be thin and long like blades, hence the name "blade battery". It adopts a CTP (Cell-to-Pack) module-free solution, which changes the design of the battery pack by eliminating the traditional battery casing structure and using the blade battery as both the beam and the core of the battery. 


The blade batteries are arranged with honeycomb aluminum plates, with two high-strength aluminum plates attached to the top and bottom, allowing for higher space utilization and the ability to fit more battery cells in the same space compared to traditional modules.

The Blade Battery is known for its exceptional cycle life. It can endure a high number of charge and discharge cycles without significant capacity degradation. This longevity results in a longer lifespan for energy storage systems, reducing the need for frequent battery replacements.


Safety is a paramount concern in battery technology, and the Blade Battery excels in this aspect. It has a unique prismatic cell design that minimizes the risk of thermal runaway and fire. The Blade Battery is less prone to overheating and thermal propagation, making it a safer option for energy storage systems.
