  • Publication number: 20190326637
    Abstract: The present disclosure relates to the technical field of lithium-ion battery, and particularly, to an electrolytic solution and a lithium-ion battery including the electrolytic solution. The electrolytic solution includes additives, and the additives include an additive A and an additive B. The additive A forms a film on the surface of the positive electrode and effectively prevents interface side reactions at the positive electrode. Comparing with the additive A, the additive B is preferentially reduced to form a film at the negative electrode, avoiding an increase in impedance and deterioration of cycling dynamic performance, etc., caused by film formation of the additive A on the negative electrode. The combination of the additive A and additive B imparts the battery with a reduced gas production, a higher capacity retention rate and a lower impedance at high temperature.

  • Patent number: 9846605
    Abstract: A server computing architecture is provided that uses minimal download features and includes error failover functionality. A server computer may receive an electronic page request and calculate a delta between a known static baseline electronic page and the requested electronic page. The static baseline electronic page may include an electronic page without content that utilizes a master electronic page. The master electronic page may include shared content for electronic pages associated with a website. The server computer may further determine whether one more errors are associated with rendering the calculated delta, render a payload comprising only the calculated delta upon determining an absence of the one or more errors and failover to one or more options upon determining that the one or more errors are associated with rendering the calculated delta.

  • Patent number: 9237431
    Abstract: An approach is provided for receiving a voice-based emergency call and routing it to a local Public Safety Answering Point (PSAP) along with anchoring information identifying the caller and their location. The PSAP may provide options for the caller to choose to use non-voice-based messaging service concurrent with the voice-based emergency call. If the caller desires and chooses to communicate via non-voice-based messages, then a text messaging application at the PSAP is used to communicate with the caller. The PSAP utilizes the anchoring information obtained from the concurrent voice-based emergency call when communicating with the caller.

  • Patent number: 9037133
    Abstract: A message broadcast from a radio frequency transceiver of a cell of a mobile communication network is based on a profile of a proximity service offered to users of mobile devices within the cell coverage area. The message includes information about the proximity service for prompting the users to respond to receive further communication regarding the proximity service. A user operates a mobile device to respond indicating a request to receive further communication regarding the proximity service. In some examples, upon receiving the response, an application server coupled to the network transmits service content as part providing the proximity service to the user. In other examples, if the service profile and a user profile are compatible so as to allow the direct communication, the application server sends instructions to enable direct communication between the mobile device and a proximity service server of the proximity service provider.
