Recent progress in thin separators for upgraded lithium ion
As shown in Fig. 2b, c and d, three major advantages are reflected in lithium-based batteries with thin separators:1) high energy density, 2) low internal resistance and 3) low material cost. Specifically, among the available space inside the batteries, thin membranes give more room for active materials and also make it possible to carry more functional coatings.
Separator Material
Thin battery separators provide several advantages that can improve battery performance and design. First, thinner separators enable higher rate capacities to be attained. This means that the battery is able to produce higher current densities across the membrane because the electrical resistance of the separator can be lowered by reducing the separator''s thickness.
