StoreDot, a company specializing in extreme fast-charging (XFC) battery technology for electric vehicles (EVs), has announced the development of silicon-dominant 4695 cylindrical battery cells. This advancement completes the company’s range of battery cell formats, which now includes pouch, prismatic, and cylindrical designs.
The new 4695 cylindrical cells address challenges commonly associated with silicon-based batteries, such as swelling, enhancing both versatility and performance. The 46xx cylindrical form factor, already adopted by several major automakers, is anticipated to significantly impact the EV industry by providing faster charging times and higher energy density.
While detailed fast-charging data is yet to be released, StoreDot anticipates that its cylindrical cells will achieve similar performance to its existing XFC technology in prismatic and pouch formats. The cells are expected to consistently charge from 10% to 80% state of charge in 10 minutes. Early integration testing indicates a cycle life of approximately 1,000 full cycles at standard charge rates. Additionally, the cells offer a volumetric energy density exceeding 800 Wh/L, which could benefit various industries requiring compact and efficient energy storage solutions.
Dr. Doron Myersdorf, CEO of StoreDot, commented on the development: “This achievement is a significant step toward alleviating range and charging concerns for electric vehicle users. Our cylindrical cells deliver rapid charging capabilities, high energy density, and durability, making them suitable for a broad spectrum of applications beyond electric vehicles.”
StoreDot’s silicon-dominant XFC technology has attracted attention from global automotive manufacturers, who are currently testing and customizing the technology for future EV models. The company’s ability to address silicon-related challenges across different cell formats sets it apart in the battery technology sector.
The new 46xx cylindrical cells are undergoing scale-up processes with StoreDot’s manufacturing partner in South Korea. Mass production is planned to begin by late 2025, aligning with the company’s commitment to advancing battery innovation and meeting growing energy demands.
StoreDot also sees potential for these cells in applications beyond the EV market. Their compact and robust design, combined with high energy density and long cycle life, make them suitable for a variety of use cases that require reliable and efficient energy storage.
