Anode Active Materials
Anode active materials are essential to the performance of every high-efficiency battery. Our advanced anode materials deliver the reliability and energy efficiency required for next-generation energy storage systems. They are optimized for use in lithium-ion (LIB), sodium-ion (SIB), lithium-air, lithium-sulfur, and multivalent metal battery technologies.
In liquid-state lithium-ion batteries, the anode and cathode are separated by a polymer-based membrane filled with an electrolyte containing lithium salts in alkyl organic carbonates. The anode active material stores lithium ions through intercalation during charging. To ensure stability and safety, it must withstand repeated cycling with minimal volume change.
Key Features and Applications
- We offer carbon-based materials such as graphite as a major anode material, celebrated for its low cost, lightweight, low working potential, and durability – the ideal choice for standard lithium-ion battery applications.
- High purity, battery grade metal oxide nanoparticles are used to enhance battery capacity, stability and more.
- Our lithium titanium oxide anode material offers exceptional safety and cycling stability. With surface modification and doping, it exhibits improved ion diffusion and conductivity, enhancing high-rate performance.
- Transition metal dichalcogenides layered structures allow for ion intercalation and have gained interest for use in hybrids.
