摘要:
The present invention relates to electrolytes comprising tetracyanoborate and an organic cation as components of electrolytes in electrochemical and/or optoelectronic devices, in particular solar cells. This ionic liquid has low viscosity and can be used as electrolyte in the absence of a solvent. Importantly, the ionic liquid remains stable in solar cells even after prolonged thermal stress at 80° C. for 1000 hours. Photovoltaic conversion efficiency remained stable and keeping more than 90% of the initial value.

An electrolyte injection and explosion proof device for use in power batteries includes a cover defining an electrolyte injection hole, a rupture plate detachably disposed on the electrolyte injection hole, and an inner liner pressing the rupture plate on the electrolyte injection hole for sealing the same. The rupture plate detachably mounted on the electrolyte injection hole via pressing or clamping can be readily replaced, so that the power battery can be continuously used when the rupture plate is broken. Additionally, the explosion proof device is mounted on the electrolyte injection hole. The number of holes defined in the cover is reduced and the sealing performance of the power battery is remarkably improved.

A cap assembly with desirable safety performance for use in lithium ion batteries, includes an insulating gasket defining a through hole therein, a rupture plate positioned in the through hole, a vent plate defining an air hole electrically connected with the rupture plate, a current interrupt device disposed on the rupture plate, and an end cap defining an air exhaust hole assembled on the current interrupt device. The current interrupt device has an upper conductive plate electrically connected with the end cap, a lower conductive plate electrically connected with the rupture plate, and a fuse electrically connecting the upper conductive plate and the lower conductive plate. When the current intensity in the lithium ion battery exceeds a predetermined value, the fuse melts to cut off the current path.
摘要:
Methods and intermediates for the synthesis of selective inhibitors of dipeptidyl peptidase IV (DPP-IV) are provided. Coupling of a carboxylate salt with a boro-proline derivative provides a protected form of a DPP-IV inhibitor, which may be deblocked to yield the medicinal compound. The carboxylate salt can be a crystalline form of a sodium salt or a dicyclohexylammonium salt. The inhibitor can be used in the treatment of diabetes.

Systems and methods are disclosed to provide converged service control and converged charging in legacy networks and IMS networks. A converged service control system of the invention includes a protocol interface and a service controller. The protocol interface receives call messages from the legacy networks and the IMS networks, and converts the call messages to a common protocol. The service controller then processes the call messages in the common protocol to provide service control to the legacy networks and the IMS networks. The service controller is also enabled to provide online and offline charging for the legacy networks and the IMS networks.

A time-shift TV (TsTV) service establishment method and a TsTV media function (MF) entity are configured to realize TsTV services in an IP Multimedia Subsystem (IMS) network. The method includes the following steps. The TsTV MF entity receives a media negotiation including content delivery channel information and content control channel information initiated by a terminal, establishes a transmission connection with the terminal based on the media negotiation result, receives a media playing request sent from the terminal through the transmission connection, and sends media information corresponding to the media playing request to the terminal through a content delivery channel established based on the content delivery channel information. A TsTV MF entity is also provided. Thus, the TsTV services are realized in an IMS network.
