Abstract: A composition of matter useful in an electrolyte, comprising a polymer including: a repeat unit, the repeat unit including a backbone section; and a side chain attached to the backbone section, wherein the side chain includes a ligand moiety configured to ionically bond to a lithium ion. The polymer has a glass transition temperature (e.g., less than room temperature) wherein the polymer is in a solid state during operation of a lithium ion battery comprising an electrolyte including the polymer.

Abstract: The present disclosure relates to computer-implemented systems and methods for location determination using light sources. An example method may include receiving, by a computer including one or more processors, a location request for a device within an indoor environment. The method may also include receiving respective light source identifiers associated with one or more light sources in the indoor environment. The one or more light sources may be in communication with the device. Additionally, the method may include accessing, by the computer, a virtual map associated with the indoor environment, and the virtual map may include one or more associations between the respective light source identifiers and respective positions, within the indoor environment, of the one or more light sources. Furthermore, the method may include determining, based at least in part on the virtual map and the respective light source identifiers, a location of the device within the indoor environment.
