Nanocrystalline Cellulose Supported MnO<sub>2</sub> Composite Materials for High-Performance Lithium-Ion Batteries

The rate capability and poor cycling stability of lithium-ion batteries (LIBs) are predominantly caused by the large volume expansion upon cycling and poor electrical conductivity of manganese dioxide (MnO<sub>2</sub>), which also exhibits the highest theoretical capacity among manganese...
