tokyo, jan 8, 2015 jcn newswire showa denko packaging co., ltd. spa, a subsidiary of showa denko k.k. sdk tokyo4004, has developed aluminum laminated films with electroconductivity to be used for packaging lithium ion batteries libs and a new technology to apply these electroconductive laminates to ultrathin libs. these new products and technology are expected to contribute to downsizing and weight reduction of libs.1. development of tableadless libs by giving electroconductivity to laminated filmsconventional aluminumlaminatedfilmbased pouch type lib laminate lib has tableads deposited on cathode and anode, through which charge and discharge are conducted. this time, spa gave electroconductivity to aluminum laminated films by surfacing one side of them with cathodic or anodicmetal layer, and successfully charged and discharged libs through these new type laminates. the new laminates eliminate necessity to deposit tableads on cathode and anode, resulting in downsizing and weight reduction of laminate libs. moreover, libs pouched with the new laminates eliminate electrolyte leakage from areas around through parts of tableads, which is a problem that conventional laminate libs have. the new laminates also give more heat radiation capacity to libs than conventional ones. thus the new laminates are expected to be applied to largesized libs including those for car use.2. development of ultrathin libs by integrating electrodes with laminated filmsfurthermore, spa developed ultrathin libs composed of aluminum laminated films integrated with cathodicanodicmetal layers and active materials. ultrathin lib is made by applying cathodeanode active materials on the surfaces of the abovementioned new laminates with cathodicanodic structure, and enclosing electrolyte and separators between these laminated films. by eliminating conventional cathodicanodicmetal layers, this ultrathin lib structure makes it possible to manufacture libs and capacitors with thickness of about 100 microm, which is less than 50 of conventional ones. moreover, ultrathin lib has improved elasticity and spirality easy to be curled. thus ultrathin libs are expected to be applied to slim type products including chip cards, and driving gears.compared with metallic libs either cylindrical type or prism type, laminate libs, which are pouched in laminated films as composite material of resin films and aluminum foils, provide higher flexibility in molding, lighter weight, and better heat dissipation. the market for aluminum laminated films used for lib packaging is expected to amount to about 25 billion in 2015, twice the scale of market in 2012. specifically, demand for small libs is growing due to the rise of smart devices such as smartphones and tablets. demand for large libs is also expected to grow due to the progress in the electrification of cars, typically represented by hybrid or electric cars&39 increasing share.these new aluminum laminated films developed by spa will be introduced at &3916th electronic components & materials expo, nepcon japan 2015&39 to be held at tokyo big sight in minato ward, tokyo from january 14 through 16, 2015.the showa denko group classifies lib materials business into the &39new growth&39 category of its business portfolio specified in the ongoing medium term consolidated business plan &39pegasus phase ii.&39 thus, in the market of aluminum laminated films used for libs, the group will work to maintain its leading market share and further improve the product quality, and will aim to ensure stable supply of its products to meet the growing demand for libs.about showa denkoshowa denko k.k. &39sdk&39 tse 4004, us shwdf is a major manufacturer and marketer of chemical products serving a wide range of fields ranging from heavy industry to the electronic and computer industries. sdk makes petrochemicals ethylene, propylene, aluminum products ingots, rods, electronic equipment hard disks for computers and inorganic materials ceramics, carbons. the company has overseas operations and a joint venture with netherlandsbased montell and nippon petrochemicals to make and market polypropylenes. in march 2001, sdk merged with showa denko aluminum corporation to strengthen the highvalueadded fabricated aluminum products operations, and is today developing nextgeneration optical communicationsuse wafers. for more information, please visit www.sdk.co.jp .source showa denkocontactshowa denko k.k. sdkpublic relations officephone 81354703235
