NexTech - Lithium-Sulfur Cells
NexTech is paving the way for the electrification of transportation with its innovative Lithium-Sulfur (LIS61) cell technology. Existing Li-ion batteries are reaching their limits in terms of specific energy. NexTech's new cells promise to surpass these limits by providing higher specific energy, unusual safety, and lower costs per kWh. Their cutting-edge sulfur-rich active material boasts an impressive 2500 Wh/kg in specific energy, outstripping metal-oxide Li-ion cathode materials by five times. The cells are designed with a focus on eliminating cobalt and nickel, which are both scarce and ethically problematic. Instead, they utilize sustainable materials like sulfur and carbon, promoting a more stable future supply chain. Additionally, these cells lack oxygen-producing elements, drastically reducing the risk of thermal runaway and associated dangers. This makes them safer for both automotive and aviation applications. NexTech is also at the forefront of developing scalable semi-solid-state technology to further enhance battery performance and safety.Incumbent Li-ion technology is reaching physical limits of specific energy after years of development, and the future electrification of transportation will rely on significant increases in specific energy and safety with dramatic reductions in cost. Our game changing LIS61 cell technology will enable unparalleled specific energy with high levels of safety and low $/kWh.
Sustainability
NexTech's cathode contains no cobalt or nickel, instead using earth abundant carbon and sulfur, which has no future supply chain shortfalls. Incumbent Li-ion technology relies on scarce, conflict-minerals such as cobalt, which are unsustainable without major breakthroughs in recycling and mineral deposit discoveries.
Energy Density
Our patented sulfur-rich active material has a maximum specific energy of 2500 Wh/kg, which is five times higher than that of metal-oxide Li-ion cathode materials.
Safety
Our cells provide unparalleled safety due to the lack of oxygen-producing materials, meaning no thermal runaway or explosion. This provides for easier transportation and increased safety for airborne and automotive applications.
Semi-Solid-State
We are developing a semi-solid-state cell technology utilizing our patented active material and a scalable semi-solid-state electrolyte composite system.
