Abstract: A cyclic sulfonate additive for an electrolyte of a lithium-ion battery (LIB) is disclosed, with a structure shown in formula I: A non-aqueous electrolyte of a LIB can be prepared with the cyclic sulfonate additive for the electrolyte of the LIB as one of additives, together with a non-aqueous solvent, and an electrolyte lithium salt, and arranged between a negative electrode and a positive electrode to fabricate a LIB. The present disclosure provides a use of the cyclic sulfonate additive in a LIB, which can effectively inhibit the reduction of battery capacity during high-temperature cycling and high-temperature storage, and can also inhibit the decomposition of an electrolyte to produce a gas.

Abstract: A system and method for providing an on-site service includes a plurality of nodes, each containing: a neighborhood node set generation module, for generating a neighborhood node set on the basis of the bidirectional link bandwidth between a local node and a neighboring node; a neighborhood information index table generation module, for generating a neighborhood information index table of the local node; a candidate service point selection module, for selecting according to a selection function a candidate service node from the set of neighboring nodes; the definition of the selection function being: for a current service request, computing the difference between the QoS of the neighboring node i executing the service request and the QoS of the local node executing the service request; if the computed difference is smaller than a set threshold, the neighboring node i serving as the candidate service node; a service scheduling module, for receiving status information and feedback information provided in real t

Abstract: A proton-exchange composite includes a polymer matrix formed from a proton-exchange polymer and ionomer particles distributed therein. The polymer has side chains with ionic groups. The particles have an average particle size of less than 20 nm and include an oligomeric ionomer that interacts with the polymer and attracts the ionic groups on its side chains. The composite may be formed by a method in which an initiator is bonded to silica particulates. The initiator is used to initiate polymerization of a precursor monomer to form a salt form of the oligomeric ionomer bonded to the silica particulates, which is then reacted with an acid to produce the oligomeric ionomer, thus forming the ionomer particles. The ionomer particles are dispersed in a solution containing a solvent and the polymer dissolved therein. The solvent is removed. The residue is cured to form the composite.

Abstract: A sol solution containing poly(titanic acid) and a planar heterocyclic ligand is provided. Titanium dioxide (TiO2) particles are formed by aging the sol solution at a temperature below about 140° C. The particles have multi-coordinated Ti-complexes comprising the heterocyclic ligand and can be substantially in the anatase phase. The heterocyclic ligands can be triazole, tetrazole, or thiadiazole. The sol solution may be prepared by aging a precursor solution. The precursor solution may contain the heterocyclic ligands and a precursor for poly(titanic acid). The precursor may be titanium alkoxide or titanium chloride. The sol solution may also contain at least one of an organic acid, a base, and a surfactant. The aged sol solution may form a colloidal dispersion of the TiO2 particles. A photo-catalytic and transparent film may be formed from the TiO2 particles by depositing a layer of the colloidal dispersion on a support.
