Tunable ultrathin dual-phase P-doped $ Bi_{2} $$ MoO_{6} $ nanosheets for advanced lithium and sodium storage

Abstract The construction of electrode materials for lithium-ion batteries (LIBs) and sodium-ion batteries (SIBs) has gradually been an appealing and attractive technology in energy storage research field. In the present work, a facile strategy of synthesizing ultrathin amorphous/nanocrystal dual-phase P-doped $ Bi_{2} $$ MoO_{6} $ (denoted as P-BiMO) nanosheets via a one-step wet-chemical synthesis approach is explored. Quite distinct from conventional two-dimensional (2D) nanosheets, our newly developed ultrathin P-BiMO nanosheets exhibit a unique tunable amorphous/nanocrystalline dual-phase structure with several compelling advantages including fast ion exchange ability and superb volume change buffer capability. The experimental results reveal that our prepared P-BiMO-6 electrode delivers an excellent reversible capacity of 509.6 mA·$ g^{−1} $ after continuous 1,500 cycles at the current densities of 1,500 mA·$ g^{−1} $ and improved rate performance for LIBs. In the meanwhile, the P-BiMO-6 electrode also shows a reversible capacity of 300.6 mA·$ g^{−1} $ after 100 cycles at 50 mA·$ g^{−1} $ when being used as the SIBs electrodes. This present work uncovers an effective dual-phase nanosheet structure to improve the performance of batteries, providing an attractive paradigm to develop superior electrode materials..
