(Phys.org) —By folding a paper-based Li-ion battery in a Miura-ori pattern (similar to how some maps are folded), scientists have shown that the battery exhibits a 14x increase in areal energy density and capacity due to its smaller footprint. Paper-based batteries are already attractive due to their low cost, roll-to-roll fabrication methods, and flexibility. The advantages of folding them into smaller sizes adds to these features and could lead to high-performance batteries for various applications.
