Project Description
Three-dimensional metal/metal oxide nanoarchitectures [1,2] are under development via ammonia-borane reduction of various salts in aqueous medium to abate volume expansion during lithium storage. The formation of voids, chains, porosity in the new architectures allows accommodating volume expansion during the lithiation and contraction during delithiation, letting battery to cycle the longer period of time with higher energy density compared to traditional batteries. New ammonia borane process is developed to create such unique architectures [3,5]
