nanostructured materials
→ the charge storage from faradaic processes occurring at the surface of the material
→ the pseudo-capacitive effect, becomes increasingly important
mesostructured materials
→ enhanced oxidation and reduction kinetics
→ the relatively short diffusion path length for ions and electrons
What is Bioenergy?
Bioenergy is renewable energy made available from materials derived from biological sources. Biomass is any organic material which has stored sunlight in the form of chemical energy. As a fuel it may include wood, wood waste, straw, manure, sugarcane, and many other byproducts from a variety of agricultural processes.

First, Substrate is consists of a plastic or glass, a portion of the OLED is supportive.Anode is a role that make electron holes when current flows by removing electron. And the upper Conducting Layer is the place that Electron Holes is being created.Emissive Layer is the place accepting an electron from Cathode and produce light.
Emissive layer and conducting layer are called organic layer beca
리튬이온전지는 음극재, 양극재, 분리막, 전해액 등 4개의 핵심소재로 구성되어 있고, 이 핵심소재들이 반응하여 에너지를 저장하고 방출합니다.
양극재는 전기가 들어오면 리튬이온을 통해 전하를 실어 나르는 역할을 하고, 음극재는 이동해 온 리튬이온과 전하를 저장하였다가 방출하는 역할을 담당
