 In these batteries, small amounts of MWNT powder are blended with active materials and a polymer binder, such as 1 wt % CNT loading in cathodes and graphite anodes.CNTs provide increased electrical connectivity and mechanical integrity, which enhances rate capability and cycle life.A paper battery is a battery engineered to use a paper-thin sheet of cellulose (which is the major constituent of regular paper, among other things) infused with aligned carbon nanotubes.
