“…This correlation could partly be caused by the irreversible lithiation of the formed Si oxides [21] and/or native metal oxides of the as-prepared samples. [43,44] Since the second cycle, two broad lithiation peaks at around 0.06 V and 0.23 V vs. Li/Li + appear in the dQ/dV curves for all the samples, corresponding to two sloping plateaus in the voltage-capacity curves. These two peaks indicate the formation of amorphous Li 2 Si and Li 3.5 Si.…”

The fast capacity degradation of silicon‐based anodes significantly limits the application in lithium‐ion battery (LIB) industries. Recently, Si−CuO composites have been reported as promising anodes in terms of being cost‐effective and technically feasible, but improved cycle stability is still desired. This work introduces a proper amount of NiO into the Si−CuO composites via a facile high‐energy ball‐milling method. The study reveals that compared to the binary Si‐CuO composites, Si−CuO−NiO samples have less pronounced volume change during the cycles due to the formation of rich‐Si NiSi2. More specifically, Si87.5(CuO)3.4(NiO)9.1 shows the highest 100‐cycle capacity retention of ∼86.9 % at 0.2 C with an average coulombic efficiency of ∼99.4 %. Moreover, the thermal stability investigation demonstrates that the temperature of 600 °C is suitable to coat a carbon layer on Si87.5(CuO)3.4(NiO)9.1, where the microstructure and the uniform element distribution produced in the milling process as well as the suppression to the cr‐Li3.75Si formation can be maintained to the maximum extent, thus with further enhanced electrochemical performance.

“…Meanwhile, compared to the partially reported Co/Ni oxides, PCNO@C chains show an excellent cycling stability (Table S1). − ICP tests before and after the experiment are performed (Table S2), and the content of lithium ions is basically the same, indicating that lithium ions do not leach into the solution after running. Figure c displays the rate performance of PCNO@C chains, SCNO chains, and CNO chains.…”

Carbon layers-coated porous Co 3 O 4 /NiO (denoted as PCNO@C) chains are synthesized by the facile solvothermal method and subsequently annealing treatment under an Ar atmosphere, which are assembled from numerous Co 3 O 4 /NiO nanosheets. Benefiting from the unique porous chain structure, the volume change of the electrode is greatly relieved during the long-term cycling processes, and then an excellent cycling stability is obtained (the reversible specific capacity of the 1000th cycle can reach 637.3 mA h g −1 at 5000 mA g −1 ). Besides, a continuous conductive network is constructed by the coated carbon layers and long chains, the movement rate of electrons is effectively accelerated, and the high rate capability is obtained (the high reversible specific capacity of 480.6 mA h g −1 is retained at 10,000 mA g −1 ). This work contributes a new idea to construct porous chain structure anode materials.
