What Does it Cover?
As the search for high-energy-density batteries continues, innovative anode materials like SiO, Si, P, SnO, and hard carbon are emerging as attractive materials because they achieve higher capacities than graphite and improved safety compared to lithium metal. However, these anode materials face obstacles such as low initial coulombic efficiency and large volume changes during use. To overcome these obstacles, Prof. Qu and coworkers developed a novel method for controlling chemical prelithiation that easily fits into current Li-ion battery roll-to-roll production processes. The method enhances the performance of these new anode materials and enables compatibility with high-energy and lithium-free cathodes.
Building on the theme of innovative materials, Dr. Xin will share insights into silicon anodes and all-solid-state electrolytes, highlighting how collaborative efforts ensure the consistent performance of these technologies.
What Will You Learn?
- Chemical prelithiation improves the initial coulombic efficiency and cycle life of alternative anode materials in Li-ion batteries.
- The integration of controlled prelithiation processes with existing roll-to-roll Li-ion battery production processes enables high-energy cathodes and lithium-free systems.
- R&D plays a crucial role in developing advanced materials for innovative energy storage solutions in electric vehicles and stationary power.
Who Should Attend?
Battery researchers and engineers, energy and battery R&D teams, and academic researchers.
