Zhuhai, China – COSMX has recently made significant progress in solid-state battery technology, with its newly developed 15,000mAh battery successfully integrated into a smartphone concept device. This marks a substantial breakthrough in the company’s high-energy-density battery technology. At the same time, COSMX’s 100% silicon anode material and high-power electrolyte technologies have been successfully adopted by clients, demonstrating strong technical expertise and innovation capabilities, and laying a solid foundation for the company’s long-term development.

In the field of semi-solid-state batteries, COSMX has achieved mass production and obtained certification from multiple customers. Several platform projects are currently progressing steadily, indicating that the company’s technical strength in the high-end battery sector has gained broad market recognition.

Over the past five years, COSMX has invested nearly RMB 5 billion in R&D, focusing on cutting-edge technologies such as solid-state batteries, stacking process, and steel-shell batteries. These efforts are aimed at building long-term technological barriers and providing strong support for technology upgrades and strategic transformation. Lithium metal anode is widely recognized as the core negative electrode material for solid-state batteries. COSMX has continued to deepen its investment in lithium metal anode technology, with industry-leading capabilities that achieve an ultra-thin initial lithium layer thickness (<20μm), high areal capacity (>4mAh/cm²), and long cycle life (>1,000 cycles at 80% DoD). These achievements have earned high recognition from industry experts.

Previously, the company established a fully inert gas-protected experimental production line for all-solid-state lithium batteries, marking a new level of independent R&D capability in this frontier field. This provides a core platform for accelerating technological breakthroughs and sample validation.

With the continuous mass production of semi-solid-state batteries, comprehensive client collaborations, and ongoing breakthroughs in all-solid-state technology, COSMX is poised to maintain a leading position in the global new energy battery market. The company will provide core power support for consumer electronics, new energy vehicles, and other fields, further expanding its share in the high-end battery market and creating long-term value for investors. Through sustained technological investment and market expansion, COSMX is establishing a first-mover advantage in the next-generation battery technology competition, injecting strong momentum for future development.
