Abstract: Lithium ion batteries and electrolytes therefor are provided, which include electrolyte additives having dithioester functional group(s) that stabilize the SEI (solid-electrolyte interface) at the surfaces of the anode material particles, and/or stabilize the CEI (cathode electrolyte interface) at the surfaces of the cathode material particles, and/or act as oxygen scavengers to prevent cell degradation. The electrolyte additives having dithioester functional group(s) may function as polymerization controlling and/or chain transfer agents that regulate the level of polymerization of other electrolyte components, such as VC (vinyl carbonate) and improve the formation and operation of the batteries. The lithium ion batteries may have metalloid-based anodes—including mostly Si, Ge and/or Sn as anode active material particles.

Abstract: Disclosed herein a depositing device for a cargo carried out by an unmanned aerial vehicle. The depositing device can comprise a receptacle enclosed from above by one or more swinging ledges forming a cargo-dropping area on the outer surface thereof, wherein the receptacle is coupled to a hanging device adapted for hanging said depositing device to a balcony railing. The depositing device also comprises a transmitter designed to transmit information usable by the unmanned aerial vehicle to determine a spatial position of the cargo-dropping area. The one or more swinging ledges are designed to tilt inwardly into the receptacle in case a force exerted by a weight of the cargo imposed on the cargo-dropping area exceeds a threshold weight, for inserting said cargo into the receptacle.
