  • Publication number: 20210377842
    Abstract: Multiple communication paths are established for communications between a User Equipment (UE) and a wireless communication network, before switching between those paths is initiated. Signaling that includes an explicit indication that the UE is to switch between the multiple communication paths is transmitted to and received by at least the UE for which the multiple communication paths were established. Responsive to the explicit indication, communications are switched between the communication paths. At least one of the communication paths includes a relay path between the UE and the wireless communication network through another UE. Establishment of the multiple paths in advance of the switching may be useful in enabling fast switching with low latency and/or no traffic loss.

  • Publication number: 20210372001
    Abstract: A recycling and synthesis of charge material for secondary batteries generates single-crystal charge materials for producing batteries with greater charge cycle longevity. Charge material particles undergo a heating for fusing or enhancing grain boundaries between polycrystalline particles. The resulting, more well-defined grain boundaries are easily etched by a relatively weak mineral acid solution. The acid solution removes material at the grain boundaries to separate secondary particles into primary particles along the grain boundaries. The resulting single crystal (monocrystalline) charge material particles are washed and filtered, and typically re-sintered to accommodate any needed lithium (lithium carbonate), and result in a charge material with larger surface area, higher lithium diffusivity and lower cation ordering.
