New Products • Components & Materials Battery Separator from Porous Power Reduces Risk Of Thermal Runaway Porous Power Technologies, LLC (PPT) has launched a line of ceramic-filled battery separators designed to improve the thermal stability and safety of the large-format lithium-ion batteries used in electric vehicles, flat-cell consumer electronics and many high-power applications. At high temperatures that can cause other separators to fail, PPT’s ceramic-filled polymer separators fuse together, leaving a thin film of ceramic particles between the electrodes and reducing the likelihood of hard shorts that can lead to thermal runaway and catastrophic cell failure. Unlike dense ceramic coatings applied as a separate layer on competing separators, PPT’s products contain ceramic particles that are thoroughly distributed throughout their chemically inert PVDF polymer. The particles reside primarily in the pore walls, leaving a large and uniform open pore structure that enables ions to pass through with less resistance and less heat generation. Symmetrix ceramic-filled battery separators are available in a variety of thicknesses to enable many cell configurations and designs. Ioxus Brings Three New Modules to Market with High Power and Energy Density Ioxus, a manufacturer of ultracapacitor technology for transportation, alternative energy, medical, industrial and consumer product markets, has unveiled three new modules: the iMOD 16 V/500F, 80 V/15F and 48 V/165F, which all deliver high power and energy densities. Notably, the iMOD 16 V/500F provides power density up to 95 percent greater than modules currently on the market. The iMOD 16 V/500F, 80 V/15F and 48 V/165F have several applications integral to the success of global industries, including in stop/start transportation systems, regenerative energy capture, grid power storage systems, backup power/UPS and robotics. In addition to addressing needs of key industries, these modules were designed with the customer experience in mind. The iMOD 80 V/15F can be ordered as a preassembled field replacement unit (FRU), eliminating up to 10 hours of labor and reduc- 24 Battery Power • May/June 2013 ing the opportunity for assembly error. The iMOD 16 V/500F has customizable end plates to fit a variety of alternate mounting configurations based on a customer’s need. Cabot Launches First Graphene-Based Additive to Improve Energy Density of Lithium-Ion Batteries Cabot Corp. has launched the LITX G700, the company’s first graphene-based additive for high energy density lithium-ion battery applications. Utilizing graphene material developed on the basis of a new technology platform, this additive helps lithium-ion battery manufacturers achieve improved cell performance. Battery developers for applications in electronics and electric vehicles have reached the limit in reducing the loadings of conventional carbon additives. As a result, many are resorting to alternatives such as carbon nanotubes that add significant cost as well as manufacturing challenges. The LITX G700 conductive additive is a graphene-based additive designed for use in electric vehicle and high-end consumer electronics in which better driving range and longer run times are critical performance features. This additive is designed to deliver the conductivity needed to achieve very high energy densities in lithium-ion batteries at ultra-low loadings in comparison to conventional additives. Less loading or volume allocated to conductive additives enables more volume to be available for energy storage materials. As a result, the LITX G700 graphene-based additive delivers step change performance in conductivity at ultra-low loadings and is easily incorporated into battery electrodes. Graphene is a thin sheet of carbon atoms that has high electrical and thermal conductivity, and is mechanically strong. It is used as a performance-enhancing material in composites to add strength, stability, electrical and thermal conductivity, and other properties at lower loading levels than traditional materials. Its unique shape and structure provide different application opportunities from standard carbon additives. Specifically, graphene’s unique properties help to balance the overall electronic and ionic conductivity of lithium-ion battery cells that could not be achieved with other carbon additives.
