WebThe charge density of PEs affects the properties of the PE bilayers. The charge density can be expressed by the number of ion pairs per number of carbon atoms in the repeating unit of PEs. PEs with high charge density prefer to adsorb almost flat on the surface, leading to dense PE bilayer films. WebAlternately, a battery with high energy density can deliver the same amount of energy, but in a smaller footprint compared to a battery with lower energy density. This greatly expands the possibilities for battery applications. In factory or warehouse settings, forklift batteries can weigh thousands of pounds.
