Our efforts towards lithium-sulfur batteries are being promoted in collaboration with major domestic and international partners as one of our challenging development themes, focusing on the practical application of medium to large lithium-sulfur batteries. With an energy density of over 400Wh/kg, they are very high-density and lightweight, making them suitable as the main power source or auxiliary power for airplanes, airships, and balloons that conduct observations at high altitudes for several months or more. Additionally, compared to conventional liquid lithium-ion batteries, they offer significantly higher safety and a wider usable temperature range, preventing potential fire accidents and minimizing the necessary components for insulation. **Features** - Excellent for low-rate long-duration operation - Higher safety - Low-cost materials - Maintenance-free - Low environmental impact *For more details, please refer to the PDF materials or feel free to contact us.*

Our company is promoting the development of solid-state batteries based on the technology cultivated through the provision of laminated lithium-ion batteries. We aim to contribute to society by realizing the practical application of solid-state batteries and striving for a de facto standard of solid-state batteries with high market appeal through alliances with various partner companies and research institutions. Additionally, by developing "sheeting" technology related to the manufacturing process of electrodes and combining "third battery structures" with "solid-state batteries," we achieve high pressure between electrodes, which is difficult with can-type or aluminum laminated batteries, thereby contributing to the practical application of medium to large solid-state batteries.

Our company has successfully improved the reliability of sealing and the rigidity against pressure, which were difficult to achieve with aluminum laminate packaging, by using SUS and nickel-plated steel sheets instead of aluminum laminate materials. By sealing the exterior material using laser and resistance welding technology, and employing our patented "Rivet-type Electrode Extraction Structure," the new battery shape ensures high safety and long-term reliability in the battery pack while maintaining design flexibility for laminate cells. Furthermore, by adopting the "third battery shape," the exterior body has increased rigidity compared to traditional aluminum laminate, allowing for a simplified structure for cooling the cells with very high pressure or heat dissipation plates. [Features] ■ It is possible to ensure the following advantages of existing battery shapes in a single solution: - Laminate sheet type: high energy density, excellent heat dissipation, lightweight, design flexibility, pressure application to electrodes - Can type: sealing reliability, exterior strength, ease of handling *For more details, please refer to the PDF document or feel free to contact us.

For solutions represented by drones and flying cars, requirements include "high capacity," "mid-rate," "light/small," and "high safety." Batteries that can withstand high loads in a short time while ensuring safety are necessary. At Enax, we are currently developing silicon anode cells with performance equivalent to widely used lithium polymer cells, significantly improving safety, reliability, and lifespan, which are their drawbacks, through module technology for new solutions. In collaboration with material manufacturers possessing core technology in silicon anodes, we are addressing concerns about lifespan and safety by utilizing a cell structure unique to laminated cells that allows for external pressure application to suppress silicon expansion. 【New Si-based Battery】 ■ Weight Energy Density: 180–240 Wh/kg ■ Input/Output Performance: Continuous 10C, Momentary 20C ■ Safety Performance: Fire Resistance 〇, Drop Impact 〇 ■ Battery Lifespan (Cycles): 〇 500 cycles *For more details, please refer to the PDF document or feel free to contact us.
