PAPER-BASED LITHIUM MAGNESIUM OXIDE BATTERY

摘要

Replacing of metal current collectors with flexible materials has great potentials of improving flexibility, weight, and applications of Li-ion batteries. This paper presents fabrication and experimental results of lithium magnesium oxide (LiMn_2O_4) battery using conductive paper current collectors. A thin layer of LiMn_2O_4 was coated on paper current collectors using air-spray method, and half-cell devices were fabricated. Experimental capacity of 130 mAh/g is reported. The porous structure of cellulous fibers in the current collector improves the adhesion of electrode materials on the substrate, which provides higher flexibility and lighter weight.
