  • Publication number: 20240274798
    Abstract: A cathode material made of cobalt-free layered oxide. A primary particle of the cathode material includes a lithium-poor phase LiaM2-aO2 and a lithium-rich phase Li2M?O3 which are of a layered-like structure. Coordination between these two phases is capable to address an issue of low energy density, low initial coulombic efficiency, and low lithium utilization of conventional cobalt-free layered cathode materials. The novel cobalt-free layered cathode material can be applied to lithium-ion batteries to achieve a low cost and high energy density.

  • Publication number: 20240218516
    Abstract: The present disclosure provides a binding agent for graphene film transfer, comprising 5-95 parts by weight of a volatile organic solvent A and 95-5 parts by weight of a volatile organic solvent B. The present disclosure does not use a transition substrate, which greatly reduces the cost, and realizes low-cost transfer. Moreover, the binding agent can be completely volatilized, so that the transferred graphene has no residual glue. The graphene is pure and pollution-free, and a high-quality graphene film can be obtained after the transfer of the graphene. Furthermore, high-quality multi-layer transfer can be achieved and the quality of multi-layer graphene can be guaranteed. Moreover, the graphene can be transferred to any different target substrates.

  • Publication number: 20220065879
    Abstract: A method for automatic sampling of immune cells from a biological fluid sample, e.g., whole blood, deposited in a well of a microwell plate. The sample contains red blood cells (RBCs) and magnetic beads which are designed to bind to the RBCs. The microwell plate is placed on a shaker having a magnetic adapter including at least one magnet. The magnet causes the RBCs bound to the magnetic beads to be attracted to and migrate to a wall of the well (e.g., the bottom or side wall) and be held against the wall. The shaker is then operated to shake the microwell plate in a manner and for a time period so as to suspend substantially evenly or homogeneously the immune cells in the biological fluid sample within a region of the well but still retain the holding of the RBCs to the wall of the well such that the immune cells are substantially isolated from the RBCs in the region of the well.

  • Patent number: 10074856
    Abstract: A lithium-rich manganese-based positive electrode material represented by formula (I). In an X-ray diffraction pattern of the lithium-rich manganese-based positive electrode material, a ratio of a diffraction peak intensity of a Bragg angle near 18.7° to a diffraction peak intensity of a Bragg angle near 44.6° is 1.10 to 1.24. A method for preparing the lithium-rich manganese-based positive electrode material comprises: mixing a lithium-rich manganese-based compound with a lithium remover; and under the effect of the lithium remover, removing part of Li2O from Li2MnO3 in the lithium-rich manganese-based compound, so as to obtain the lithium-rich manganese-based positive electrode material. Due to the reduction of the irreversible product Li2O, the initial coulombic efficiency is improved; because of existence of lithium vacancy and oxygen vacancy, the lithium-rich manganese-based positive electrode material has good rate performance and cycle performance.
