abstract = {Li[Ni1–x–yCoxAly]O2 (NCA) and Li[Ni1–x–yCoxMny]O2
(NCM) cathodes have been the archetypes of current
high-energy-density cathodes for Li-ion batteries. A hybrid
of NCA and NCM cathodes, a quaternary system consisting of
Li[Ni0.89Co0.05Mn0.05Al0.01]O2 (NCMA) was benchmarked
against NCM and NCA with similar Ni contents. The quaternary
NCMA cathode delivered a capacity of 228 mAh g–1 and
outperformed the benchmarking cathodes in long-term cycling
stability $(85\%$ after 1000 cycles). The reduction in the
volume change during deintercalation and the enhanced
intrinsic mechanical strength confirmed by the
single-particle compression test suppressed the microcrack
nucleation and propagation. Microcrack suppression was
important because microcracks serve as channels for
electrolyte infiltration and lead to subsequent surface
degradation of internal surfaces. The proposed NCMA cathode
provides extra cycling stability, which is essential for
electric vehicles, which require a long battery life and
improves the thermal stability of the cathode, which
contributes to a safer battery.},
