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
What is Amorphous metal?
Polycrystalline grains of varying shapes and sizes
Misaligned planes of atoms slip past each other easily, absorbing energy and allowing dislocations to move, making deformation permanent.
Grain boundaries represent weak spots
Also called Metallic glasses or glassy metals
Cooled faster than atoms can rearrange into a crystal.
Dislocation movement obstructed s
conductivity measurements. The results show that the Au parti- cles are well-protected by the dithiol linker molecules and do not fuse into larger un- ited. The thin film material obtained clearly exhibits nonmetallic properties(i.e., electro -hopping conductivity and optical constants very different from those of metals).

Product strategy
Emphasized ladyishness
☞Hired talented designers and staffs from local
Round and spherical shape of containers symbolized ladyishness
☞container design grabbed women’s attention
“Efficient”
