Cation-ordered Crystal Structure
- Aligned structures can act as pillars between layers
- Advantageous for high voltage and long life characteristics
Conventional Cathode
Cation-ordered crystal structure
- Synergistic effect combined with concentration gradient and rod-shaped cathode materials
Conventional Cathode
When conventional cathode is charged,
the layered structure is twisted and collapsed
Cation-ordered crystal structure
When cation-ordered cathode is charged,
the atomic array maintains the layered structure
Nanocomposite
- Structural durability upon repeated electrochemical cycling → High performance
- During the deintercalation of Li+ ions from host structure, the nanostructure crystal structure act as a pillar and stabilize the delithiated cathode structure
