Summary: In recent years, there has been a growing interest in finding sustainable alternatives to conventional materials in various industries.

As a result, researchers have been exploring alternative materials such as bamboo and corn cob, it has emerged as a promising candidate for substitution of carbon black in zinc-carbon battery. The system incorporates a two-stage process to produce activated carbon: First is the carbonization process where the dried materials which is bamboo and corncob. Pyrolysis is the method used to produce charcoal-like structure; raw materials are subjected to high temperatures (600°C) in the absence of oxygen. During the carbonization process volatile compounds are released such as hydrogen, oxygen, and other non-carbon material, leaving carbonaceous residue.

In recent years, there has been a growing interest in finding sustainable
alternatives to conventional materials in various industries. However, the
production of carbon black involves carbon-intensive processes, leading to
concerns about its environmental impact. As a result, researchers have been
exploring alternative materials such as bamboo and corn cob, it has emerged as
a promising candidate for substitution of carbon black in zinc-carbon battery. The
system incorporates a two-stage process to produce activated carbon: First is the
carbonization process where the dried materials which is bamboo and corncob.
Pyrolysis is the method used to produce charcoal-like structure; raw materials are
subjected to high temperatures (600°C) in the absence of oxygen. During the
carbonization process volatile compounds are released such as hydrogen,
oxygen, and other non-carbon material, leaving carbonaceous residue. Second
process was activation process, the carbonized bamboo and corncob are
subjected to pyrolysis which has high temperature (900°C). The activation process
increased the surface area and porosity of carbonized material, which enhances
its ability to absorb and conduct electricity. Then the materials are subjected to
chemical activation, this method involves impregnating the carbon with chemical
activating agents such as phosphoric acid (H3PO4) and potassium hydroxide
(KOH) (Ismail et al., 2022). The activated carbon is assembled and subjected to
testing to produce results for output voltage and discharge rate of different cathode
ratio of both plant-based material which is bamboo and corncob
