Lithium battery metal element-lithium

Lithium (Lithium) is a metal element, which is located in the second cycle IA family in the element cycle table. The element symbol is Li, its atomic order is 3, the atomic amount is 6.941, the corresponding single quality is silver -white soft metal, which is also the smallest density. Metal. Its melting point is 180.5 ° C, the boiling point is 1342 ° C, and the heating capacity is 3.58 kj/kg · k. Lithium is often used in atomic reactors, light alloys and batteries. Metal lithium can enter the human body through various channels and cause lithium poisoning by organ tissues, which can cause central nervous system poisoning and kidney failure. Lithium and its compounds are not as typical as other alkaline metals, because the charge density of lithium is high and has a stable dual -type dual -electron layer, which makes lithium easily polarly polarized other molecules or ions, but itself is not easy to be extremely extremely extreme change. This affects the stability of it and its compounds.
