400Wh/kg Semi-solid State Battery 5-10C High Discharge Rate 50Ah Drone Battery Cells

Product Introduction

The 400Wh/kg Semi-solid State Battery represents a revolutionary leap in energy storage technology, balancing exceptional performance, enhanced safety, and practical scalability for diverse high-demand applications. As a cutting-edge semi-solid state battery, it features a hybrid electrolyte system with only 5% liquid content, combining the ion conductivity of traditional electrolytes with the stability of solid components to achieve an industry-leading energy density of 400Wh/kg. This breakthrough enables devices and vehicles to achieve longer runtime without increasing battery size or weight—critical for electric mobility and portable power needs.

With a cycle life exceeding 800 times, it maintains reliable performance through repeated charge-discharge cycles, while supporting ultra-fast charging that delivers 400km of range in just 12 minutes for electric vehicles. Designed to operate in extreme temperatures (-30℃ to 60℃), this semi-solid state battery outperforms conventional lithium-ion batteries in both cold and hot environments, with a low self-discharge rate of less than 1% per month. Whether powering electric vehicles (EVs) for over 1000km of range, enabling extended flight for eVTOLs, supporting grid-scale energy storage systems, or enhancing the runtime of consumer electronics, the 400Wh/kg Semi-solid State Battery sets a new standard for energy density, safety, and versatility in advanced energy storage.
