Abstract: Provided are multilayered flexible battery interconnects for interconnecting batteries in battery packs and methods of fabricating thereof. A multilayered flexible battery interconnect comprises insulating layers and two conductive layers, stacked together and positioned between the insulating layers. One conductive layer is thicker than the other. The thinner conductive layer comprises flexible tabs for connecting to batteries and, in some examples, comprises voltage sense traces. The smaller thickness of these flexible tabs ensures welding quality and allows using less energy during welding. The battery cell contacts, to which these flexible tabs are welded, can be significantly thicker. Furthermore, the smaller thickness enables fusible link integration into flexible tabs. At the same time, the two conductive layers collectively conduct current within the interconnect, with the thicker layer enhancing the overall current-carrying capacity.

Abstract: For the shipping industry, these fuels provide solutions to long outstanding technical problems that heretofore hindered supply of low sulfur marine fuels in quantities needed to meet worldwide sulfur reduction goals. Marine shipping use of high sulfur bunker oils is reported as largest source of worldwide transportation SOx emissions. When ships on the open seas burn cheap low grade heavy bunker oils high in sulfur, nitrogen and metals, the SOx, NOx, and metal oxides go to the environment. This invention converts essentially all of each barrel of crude feed to a single ultraclean fuel versus conventional refining where crude feed is cut into many pieces, and each piece is sent down a separate market path meeting various different product specifications. When in port, ships can use these fuels to generate and sell electricity to land based electrical grids to offset fuel cost in an environment-friendly manner.
