EXENCELL unlocks the blue ocean energy storage market with the solid-state battery cells

As the next generation of battery cell technology, solid-state cells have become a common option in energy storage industry, the players in the whole industry chain are accelerating technology upgrade and reshuffling energy storage market.

The competition of the next generation 300Ah+ energy storage cells has been extended to multiple directions such as high voltage, long cycle, liquid cooling, and solid-state, and the market is turning white-hot for the second-generation energy storage cells. Solid-state cells have become the core direction of the upgrade of the second-generation 300Ah+ energy storage cells by comprehensive improvement in safety, energy density, cycle life and other aspects.

In response to the demand for battery cells with high safety, high energy density and long cycle, EXENCELL makes the running in combining 300Ah+ cells with solid-state concept, unveiling 320Ah solid-state energy storage cells. EXENCELL 320Ah solid-state energy storage cell, actual capacity ≥ 320Ah, energy density ≥ 182Wh/kg, cycle life (normal temperature) ≥ 6000cls, and no fire/ explosion during acupuncture and overcharge tests. Regarding application scenarios, EXENCELL 320Ah solid-state energy storage cell can be used in grid scale energy storage, CCI energy storage, electric vessels and other scenarios.

From the perspective of battery form and industrialization rhythm, pouch cells are compatible with solid-state cells in terms of packaging form, which can better adapt to the expansion and contraction of solid-state electrolytes, and is conducive to the extension of life cycles, thus the fulfillment of solid-state pouch cells is feasible. From the perspective of application, pouch cell technology is mature, and has high energy density and safety. Pouch cells has been widely used in 3C consumer electronics, and penetrated into low-altitude economy, humanoid robots, AI intelligent computing center backup power and other market segments, boosting the commercialization of solid-state cells.

Based on this trend, EXENCELL also unveils its 56Ah solid-state pouch cell, which supports 3C rate charging and 5C rate and higher discharging. Regarding safety performance, EXENCELL solid-state pouch cell adopts a fully sealed design, with good flexibility, waterproofness and safety, and has successfully passed a number of rigorous safety tests, showing strong and reliable safety performance. In the cutting test, the cell structure is still intact and can be used normally after multiple cuttings; In the waterproof test, the cell that had been cut several times was energized and placed in the water tank, and its circuit was still functional. In addition, in terms of flexibility, pouch cells are generally packaged in aluminum-plastic film, and the shape design can be customized according to customers' needs into their required shape and capacity, so as to meet the needs of different application scenarios.

As the next-generation battery cell technology, solid-state cells can not only be widely used in the field of energy storage, but also branch out into more market segments under the combination of different battery forms. EXENCELL premiered a variety of solid-state cell products at the beginning of 2025, demonstrating its steady and sustained development on the track of energy storage.
