The shell features

Lithium, atomic number 3,Atomic weight6.941, it is the lightestAlkali metal elements.In order to improve safety and voltage, the scientists invented the graphite and cobalt acid lithium materials such as to store lithium atoms.The molecular structure of these materials, formed the nanometer level of small storage grid, can be used to store lithium atoms.In this way, even if the battery shell is broken, and oxygen to, also because of too much oxygen, into these small store, making lithium atoms will not avoid contact with the oxygen blast.
