background

● The conventional secondary batteries are made by coating active materials on metallic foils with conductive fillers and binders. These non-capacitive components accounts for significant mass function.
● Mass and cost of batteries will be minimized  if electrodes are built on stable separators with minimal use of such components.

summary

● Original CNT Sponge-Based Battery – holds highly capacitive active materials (S cathode and Si anode) within light-weight, conductive, flexible CNT matrix, allows reversible volume change (S expands and Si shrinks during discharge) while conserves the total cell volume
● Novel design with practical production process will realize “Soft Batteries” with innovative capacity at low cost
