Electricity Generation from Bamboo Nanoparticles Processed by High Energy Milling without Thermal Treatment Mixed with NaOH

The purpose of this research is to utilize bamboo as an energy-harvesting material. Energy harvesters are produced from nanomaterial-sized bamboo. This research aims to make bamboo nanomaterials with a high-energy milling process without heat treatment as a producer of electrical energy. Bamboo nanomaterials contain a chemical composition of C, O, Si, and K with a more positive electrical charge. The addition of NaOH negatively charges the electrolyte solution due to the presence of OH-. The concentration of NaOH specifies the production of electricity because the energy gap decreases from 0.48 eV to 0.39 eV. During the electricity generation process, some of the Al electrodes dissolve into the electrolyte and form a more regular crystal structure so that the energy gap decreases further to 0.28 eV, which has a stronger electricity generation capacity. The electrical voltage produced in the battery cell is around 768 mV.
