Lithium-ion batteries are now widely used for applications ranging from cell phones to electric vehicles. Further increase in energy density will require the use of new materials. Our group focuses on advancing high-capacity Si-based anode for next-generation lithium-ion batteries, developing technologies to suppress volume expansion and improve safety of the battery.
In addition, the limited capacity of the corresponding cathode is also an obstacle to achieve high energy density. Our group aims at designing novel cathode materials with stability structure that can undergo anionic redox reaction with the oxygen atoms in the lattice to realize a specific capacity of more than 200 mAh/g for lithium-ion and sodium-ion battery applications.
