Study shows paper-folding concepts can compact a Li-ion battery and increase its areal energy density

Green Car Congress

Researchers at Arizona State University have shown that paper-folding concepts can be applied to Li-ion batteries in order to realize a device with higher areal energy densities. These initial results showed that the Li-ion batteries can still exhibit good electrochemical performance even after multiple folds, they said.
