  • Publication number: 20190229361
    Abstract: A secondary battery having improved safety and a manufacturing method thereof, which can suppress a voltage drop, heat generation, and/or ignition due to a minute short between a positive electrode plate and a negative electrode plate by preventing or substantially preventing an electrode assembly from moving within a laminate exterior case due to drop impact and/or collision are provided. A secondary battery includes: an electrode assembly including a first electrode plate, a second electrode plate, and a separator between the first electrode plate and the second electrode plate; a pouch exterior case including a planar long side region and a short side region to surround the electrode assembly; and adhesives in a dot array configuration at an outermost portion of the electrode assembly facing the planar long side region of the pouch exterior case.

  • Patent number: 8143035
    Abstract: The invention relates to the synthesis of polyketides in Actinomycetes by overexpression of pantothenate kinase and supplementation with pantothenic acid. This results in increasing in vivo CoA production and thereby drives increased production of secondary metabolites, such as polyketides.
