Here, we demonstrate that the structural evolution of Li-rich cathodes can be significantly inhibited by intentional introduction of certain adventive cations (like Ni2+) or by premeditated reservation of original Li+ ions residing in the Li slab in the delithiated state.

The effect of the composition of lithium nickel-manganese-cobalt oxide (NMC) cathodes on the cycling stability of LiNixMnyCozO2 during high-voltage operation has been systematically investigated. The results demonstrate that the Co content has a dominating impact on the stability of NMC cathodes during high voltage cycling due to the significant overlap between the Co3+/4+ t2g band and the O2− 2p band.

A nanostructured Li4C8H2O6/graphene composite exhibits a highrate capability and ultra-long cycling life in rechargeable Li-ion batteries. The improved conductivity, nanostructure morphology, and chemical-bond interaction between Li4C8H2O6 and graphene contribute to the superior electrochemical properties.

A Li-ion conducting hybrid film consisting of a garnet-type ion conductor and a polymer electrolyte is proposed as a protective layer for a Li metal anode. The hybrid ion-conducting layer allows Li deposition only underneath it and effectively suppresses Li dendrites, yielding Li metal anodes with excellent cycling stability.

Hydrogenated vanadium oxide nanoneedles were prepared and show superior lithium storage properties, with a discharge capacity of 941 mA·h·g−1 at 100 mA·g−1 and a reversible capacity of ~285 mA·h·g−1 after 1,000 cycles at 5 A·g−1 when tested as the anode in a Li ion battery.

A novel hierarchical nanocomposite composed of CoS2 nanoparticles embedded in N-doped carbon nanotube frameworks was synthesized using a two-step metal-organic-framework-engaged strategy. Owing to its unique structural features and desirable chemical composition, the obtained nanocomposite exhibited enhanced electrochemical properties for use as an anode material for lithium-ion batteries.
