Controlling the Primary Particle of High-Nickel Cobalt-Free Cathodes for Highly Stable Lithium-Ion Batteries
https://doi.org/10.1007/s11814-025-00447-8
Abstract
Lithium-ion batteries (LIBs) are bright energy-storage devices owing to their superior energy density and low memory
eff ects. High-nickel cobalt-free Li[Ni 0.9 Mn 0.1 ]O 2 (NM90) is a promising cathode material owing to its high energy density,
low cost, and nontoxicity. However, high-Ni cathodes suff er from cation disordering and short lifecycle properties. Therefore,
we fabricated well-aligned primary particles by controlling the concentration of chelating agents during co-precipitation.
Appropriately aligned primary particles facilitated the transport of lithium ions, and the Mn ions in NM90 provided frameworks
with highly stable structures. The fabricated NM90_4.8 M electrodes exhibited superior cathode performances,
including a noticeable specifi c capacity of 149.9 mAh/g with an outstanding capacity retention of 87.4% after 100 cycles
during a current density of 1C and a superior discharge specifi c capacity of 196.1 mAh/g at a current density of 0.2C. The
NM90_4.8 M cathode can provide the next-generation active materials that aff ord long-life and ultrafast LIBs, which are
discussed in terms of cost effi ciency.
