With the rapid development of the new energy industry, lithium battery applications are expanding continuously, and market demand for high energy density, low-cost lithium batteries continues to grow. Cathode materials are the core and key factors determining lithium battery performance and cost. Among numerous candidate materials, Li-rich manganese-based materials, primarily composed of affordable and abundant manganese, are disrupting traditional power battery technology routes with their dual advantages of high energy density and lower costs.
More critically, Li-rich manganese-based materials can achieve a maximum energy density of approximately 1,000 Wh/kg driven by both cationic and anionic redox reactions, making them the only cathode material system currently capable of achieving over 500 Wh/kg in lithium batteries. This positions them as one of the key technologies for ultra-high energy density all-solid-state batteries.
On September 24, 2025, Beijing Easpring Material Technology Co.,Ltd., a global leading lithium battery cathode material company, announced that through continuous technological iteration, it has systematically solved key technical challenges of ultra-high capacity Li-rich manganese-based materials and successfully developed Li-rich manganese-based cathode materials suitable for ultra-high energy density all-solid-state batteries.
According to reports, Beijing Easpring Material Technology's Li-rich manganese-based materials can achieve discharge specific capacity of 280-305 mAh/g in all-solid-state battery testing, while demonstrating high tap density, high specific capacity, long cycle life, and excellent compatibility with solid-state electrolytes. The related performance indicators are at industry-leading levels.
Simultaneously, Beijing Easpring Material Technology has systematically deployed Li-rich manganese-based cathode materials for different application scenarios: for liquid battery applications, the company has developed medium-to-high capacity (220-250 mAh/g) products and is steadily advancing their automotive applications; for all-solid-state battery applications, it has developed products with ultra-high capacity (>280 mAh/g), with comprehensive performance leading the industry.
Furthermore, Beijing Easpring Material Technology indicated that its Li-rich manganese-based material customers already cover leading lithium battery companies in China, South Korea, Europe, and the United States, demonstrating that the company is at the forefront of the industry in terms of Li-rich manganese-based material commercialization progress.
Beyond Li-rich manganese-based materials, Beijing Easpring Material Technology has also made positive progress in solid-state lithium battery materials. The company stated that with over twenty years of deep expertise in the lithium battery cathode material industry and substantial technical accumulation, it began research and development layout for solid-state lithium battery cathode materials years ago.
Currently, the company has systematically deployed oxide, sulfide, and halide solid-state battery material systems. The company's all-solid-state cathode materials employ ultra-stable fast ion conductor modification processes, achieving ultra-high capacity and long cycle life in all-solid-state battery systems, and have begun 10-ton scale batch shipments. The company's solid-state lithium battery related products have been introduced to multiple solid-state battery customers including Qing Tao, WeLion, ProLogium, Ganfeng Lithium, and CATL New Energy.
Regarding solid-state electrolytes, Beijing Easpring Material Technology also possesses industry-leading technology research and development capabilities. The company has successfully developed chlorine-iodine composite sulfide solid-state electrolytes with high ionic conductivity and good interfacial wettability, achieving stable preparation with scalable supply capability.
The "chlorine-iodine composite sulfide solid-state electrolyte" was first proposed by Beijing Easpring Material Technology. It can be used in all-solid-state batteries and effectively reduce the solid-solid interface pressure required for solid-state lithium batteries to achieve high ionic conductivity, providing technical solutions for reducing solid-state lithium battery manufacturing difficulty and costs, and enabling large-scale application of solid-state lithium batteries. The company stated that iodine-containing sulfide solid-state electrolyte related products have entered batch verification stages with leading customers.
According to industry institutions' predictions, the current solid-state battery industrialization has entered a "sprint phase," with global solid-state battery shipments expected to reach 614.1 GWh by 2030, representing dozens of times growth compared to current shipments, making it a "blue ocean market" with tremendous development potential.
Overall, whether in solid-state cathode materials or solid-state electrolytes, from technology research and development, product layout to customer development, Beijing Easpring Material Technology has achieved successful positioning and precise deployment. As the solid-state lithium battery industry continues to develop, market demand for Li-rich manganese-based materials, solid-state lithium battery cathode materials, solid-state electrolytes and other products will continue to expand, and Beijing Easpring Material Technology will fully benefit, ushering in another period of rapid growth.
