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,
and better cycle stability than single silicon anode.
material breach and emergence of new norms of international environmental law.
(1) State of Necessity
Hungary says they are in the state of ecological necessity. Actually, this is main argument Hungary claims throughout the whole process of the trial. They say that the project causes critical environmental problems which they didn’t expect in 1977 when they concluded the treaty. Slovakia
● Definition of plasma
Plasma is one of the four fundamental states of matter, along with solid, liquid, and gas. It is an ionized gas consisting of a collection of charged particles, including ions, electrons, and neutral atoms or molecules. Plasma can be found naturally in the universe in the form of stars, lightning, and auroras, but it can also be artificially created and controlled for
