A nanowire battery uses nanowires to increase the surface area of one or both of its electrodes, which improves the capacity of the battery. Some designs (silicon, germanium and transition metal oxides ), variations of the lithium-ion battery have been announced, although none are commercially available.
2007 Nanowire battery A nanowire battery is a lithium-ion battery consisting of a stainless steel anode covered in silicon nanowires. Silicon, which stores ten times more lithium than graphite, allows a far greater energy density on a steel anode, thus reducing the mass of the battery.
In 2015, researchers in China used porous graphene as the material for a lithium-ion battery anode in order to increase the specific capacity and binding energy between lithium atoms at the anode. The properties of the battery can be tuned by applying strain. The binding energy increases as biaxial strain is applied. [24]
Recent experiment on nanowire solar cells has led to a remarkable improvement of the power conversion efficiency of SiNW solar cells from <1% to >17% in the last few years. [5] The ability for lithium ions to intercalate into silicon structures renders various Si nanostructures of interest towards applications as anodes in Li-ion batteries ...

Just last month, a Saudi psychiatrist deliberately drove a rented BMW SUV through a German Christmas market, killing five and injuring more than 200. His motive remains under investigation ...
2 nanowire array cathode augmented by a genetically modified M13 bacteriophage virus offers two to three times the energy density of 2015-era lithium-ion batteries. The virus increased the size of the nanowire array, which is about 80 nm across. The resulting wires had a spiked surface. Spikes create more surface area to host reaction sites.
