Biomass Derived Carbon for Electrical Energy Storage

3. Bioenergy Studies Symposium, Samsun, Türkiye, 20 - 21 Mayıs 2021, ss.81

Electrical energy storage is playing an increasing role for the portable systems such as

electronics-electronic devices (laptops, cell phones, etc.), electrical transport vehicles (cars,

airplanes, busses, etc.) that it is later converted to light, heat, or kinetic energy. The energy

storage systems used in power systems store the energy mechanically, thermally, or electrically.

Direct electrical energy storage is ineluctable issues of the energy storage technologies and

material engineering that the performance of electrical energy storage devices mostly depends

upon the material constituents.

Carbon is the preferred material for its high surface area, electrical conductivity, porosity,

thermal stability, low cost, and eco-friendship and used in energy storage is very diverse such

as nano materials (graphene, nanotubes, nano fibers, etc.), polymers, aerogels and biomass

based ones.

Carbon materials are mostly originated from fossil fuels which are diminishing and cause

climate change. On the other hand, biomass can be the only alternative, sustainable, economic,

and environmental friendly carbon resource for resolving many of the challenges. In this work,

the energy storage capacity of biomass derived carbon from industrial tea waste was examined.

The sample exhibits tunable physical and chemical properties which are favorable in terms of

advanced electrochemical energy storage.
