Phys. Rev. Materials 6, 074601 (2022) - Published 22 July, 2022

Lead halide perovskite materials doped with lanthanides can exhibit over 100% luminescence quantum yield due to quantum cutting. Defect states related to these dopants are known to play a role in the quantum cutting mechanism, but the structural changes and charge compensation mechanisms induced by these dopants have not been fully explored. Here, the authors use a combination of advanced x-ray techniques and computational modeling to elucidate the structural impact of ytterbium doping in CsPbCl3. The authors find that Yb3+, exclusively in the +3 oxidation state, replaces Pb2+ in the octahedral site with charge compensated by Pb2+ vacancies, providing clear experimental verification of a hypothesized structure.

The functionality of materials is critically dependent on structures and electronic properties. The valence of transition metal (TM) cations in complex oxides is key and each TM exhibits a fixed range of stable values. For Ni, the formal oxidation state is 2+, but can reach 3+ for certain compositions. By limiting SrNiO3 film thickness to 1 unit cell in (SrNiO3)1/(SrTiO3)n superlattices, the authors demonstrate that the Ni valence exceeds 3+ whereas the Ti valence remains at 4+, and that neither valence changes with n. This work demonstrates that the structural environment can be controlled to achieve electronic properties not normally found in bulk materials by means of superlattice formation.

REVIEW ARTICLES

Advanced single-crystal layered Ni-rich cathode materials for next-generation high-energy-density and long-life Li-ion batteries

Jianming Sun, Xin Cao, and Haoshen Zhou

Phys. Rev. Materials 6, 070201 (2022) - Published 13 July, 2022

The studies of Ni-rich cathode materials have been the top priority of research because of the high energy density and fair cycling life. However, suffering from severe crack generations and side reactions, the traditional polycrystal (PC) Ni-rich material displayed structural/electrochemical fade during cycling. Compared with PC, single-crystal (SC) Ni-rich materials exhibited excellent structural stability and cycling performance, benefiting from the limited side reaction and gas generation. In this review, the authors not only compared the structural evolution and electrochemical failure mechanisms between PC and SC, but also summarized the synthesis methods and characterization techniques of SC, which provides universal insights into the development of Ni-rich cathode materials.
