Development of lithium-rich, high-nickel-content cathodes to increase energy density of lithium-ion batteries

Nickel-rich cathodes are anticipated to function as essential components for highcapacity
lithium-ion batteries. Though it normally results in more complicated synthesis
conditions, increasing the Ni content can substantially enhance the energy density,
hence restricting its development. This study presents a straightforward one-step solidstate
procedure for synthesising Li-rich and Ni-rich (Li2NiO3) materials. The synthesis
conditions were thoroughly investigated and analysed. The study revealed that the
synthesis circumstances had a significant influence on the electrochemical performance,
especially the calcination temperature.
In addition, the study utilises a straightforward microwave-assisted approach.
The products obtained by synthesis were analysed using X-ray diffraction,
electron microscopy, and galvanostatic electrochemistry. When compared to the
original Li2NiO3, the Li2NiO3 that was exposed to microwaves exhibited a 20%
increase in capacity after undergoing 100 cycles at a rate of C/5.
