Unveiling the effect of molybdenum and titanium co-doping on degradation and electrochemical performance in Ni-rich cathodes

Materials Reports: Energy
In this work, we have applied molybdenum (Mo) and titanium (Ti) co-doping to solve the degradation of Ni-rich cathodes. The modified cathode, i.e., Li(Ni0.89Co0.05Mn0.05Mo0.005Ti0.005)O2 holds a stable structure with expanded crystal lattice distance ...

An Effective Way to Stabilize Ni-Rich Layered Cathodes [PDF]

Chem, 2020
Stable cycling with a high energy density at an affordable cost is a key challenge for the prevailing cathode material, Ni-rich layered oxides, to power the development of long-range electric vehicles. Now, Sun and co-workers introduced a Li[Ni0.90Co0.09Ta0.01]O2 cathode in Nature Energy, demonstrating great potential to overcome this challenge.

Integrated Ni and Li‐Rich Layered Oxide Cathode Materials for High Voltage Cycling in Rechargeable Li‐Ion Batteries

ChemElectroChem, 2022
Although the Ni‐rich oxide cathodes possess a high specific capacity above 180 mAh g−1, they suffer from capacity fading upon cycling to above 4.3 V due to their high surface reactivity with the electrolyte, structural layered to rock‐salt phase ...
