  • Patent number: 10030165
    Abstract: Arylclobutene-containing multi-functional monomers are useful in the preparation of arylcyclobutene-based polymer coatings. Compositions comprising one or more arylclobutene-containing multi-functional monomers and one or more oligomers comprising as polymerized units one or more arylcyclobutene monomer provide arylcyclobutene-based polymer coatings having reduced stress. Such compositions are useful in the manufacture of electronic devices.

  • Publication number: 20170187071
    Abstract: A battery electrolyte solution contains a lithium salt dissolved in a solvent phase comprising at least 10% by weight of ethyl (2,2,3,3-tetrafluoropropyl) carbonate. The solvent phase comprises optionally other solvent materials such as 4-fluoroethylene carbonate and either or both of diethyl carbonate and ethyl methyl carbonate. This battery electrolyte is highly stable even when used in batteries in which the cathode material has a high operating potential (such as 4.5V or more) relative to Li/Li+. Batteries containing this electrolyte solution therefore have excellent cycling stability.

  • Patent number: 8574773
    Abstract: A battery electrolyte solution contains from 0.01 to 80% by weight of an aromatic phosphorus compound. The aromatic phosphorus compound provides increased thermal stability for the electrolyte, helping to reduce thermal degradation, thermal runaway reactions and the possibility of burning. The aromatic phosphorus compound has little adverse impact on the electrical properties of the battery, and in some cases actually improves battery performance.
