development of the cutting-edge technologies, including Internet of things and grid energy
storage. Microbatteries with high power and energy density levels are then required and
germanium, despite its relatively high cost, is an attractive candidate in this field due to its
high specific capacity. This study is the first report of a monolithic mesoporous germanium
(mpGe) and graphene-coated mesoporous germanium nanocomposite (GPGNC) as anodes …
