Li-Ion Battery Cathodes: Enhancing Interfacial Bonding between Anisotropically Oriented Grains Using a Glue-Nanofiller for Advanced Li-Ion Battery Cathode (Adv. Mater. 23/2016).
The formation of a spinel Lix CoO2 layer in a Ni-rich secondary particle for lithium-ion batteries is reported by S. K. Kwak, J. Cho, and co-workers on page 4705, who find that the spinel-like Lix CoO2 layer, between layered primary particles, can enhance the mechanical strength of secondary particles by enhancing the interfacial binding energy among the grains. Moreover, the layer can effectively protect the unstable surface of the primary particles and offers a fast electron-ion pathway, resulting in overall enhancements of stability and kinetics in battery performance.
