Publication number: 20190326637Abstract: 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.Type: ApplicationFiled: April 22, 2019Publication date: October 24, 2019Applicant: CONTEMPORARY AMPEREX TECHNOLOGY CO., LIMITEDInventors: Jianwei ZHU, Chenghua FU, Xiaomei WANG

Patent number: 9037133Abstract: 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.Type: GrantFiled: December 27, 2012Date of Patent: May 19, 2015Assignee: VERIZON PATENT AND LICENSING INC.Inventors: Jin Yang, Xiaomei Wang, Priscilla Lau
