lithium ions storage.
Prevent the graphite anode from expanding by lithium ion intercalation
Si has theoretical capacity of 4200mAh/g
Due to it’s large volume change, pulverization can be occurred.
Silicon has high-capacity but poor cycle stability
Carbon has low-capacity but good cycle stability
So silicon/carbon composites can have higher capacity than single carbon anode
Fundamental structure is same as the general lithium polyer
battery . But some specific functional parts are to be reformed.
Functional improvement
Detailed shap have to be modified by experiment
1. 치료의 원칙
모든 분화성 갑상선암은 진단 후 가능하면 갑상선절제술을 시행한다. 수술 후 갑상선 호르몬을 투여하여 TSH를 억제하는 치료를 하면서 정기적으로 방사성옥소를 이용한 전신스캔과 혈청 갑상선글로불린을 측정하여 재발과 전이 유무를 경과 관찰한다. 수술 후 4주간 T3를 투여하고 2주
