Description
Technical field
The present invention relates to a kind of processing of solid waste sludge in technical field of sludge treatment, in particular to factory to lithium battery and profits
Use method.
Background technology
It by lithium metal or lithium alloy is negative material, using the battery of non-aqueous electrolytic solution that " lithium battery ", which is a kind of,.
Lithium metal battery is proposed and is studied by GilbertN.Lewis earliest within 1912.When the 1970s, M.S.Whittingham
It proposes and the lithium ion battery that begins one's study.Since the chemical characteristic of lithium metal is very active so that the processing of lithium metal, preservation,
It uses, it is very high to environmental requirement.So lithium battery is not applied for a long time.With the development of science and technology, present lithium electricity
Pond has become mainstream.
Lithium battery is broadly divided into two classes：Lithium metal battery and lithium ion battery.Lithium ion battery does not contain metallic state
Lithium, and can charge.5th generation product lithium metal battery of rechargeable battery was born in 1996, safety, ratio
Capacity, self-discharge rate and the ratio of performance to price are superior to lithium ion battery.Since the high-tech of its own requires limitation, now only
The company of a few countries is producing this lithium metal battery.
With progress of the epoch, the demand to lithium battery of the common people increases, dirt will produce when producing lithium battery
Mud does not handle the sludge containing fluorination calcium ion containing fluorination calcium ion in sludge, leads to environment currently on the market
Pollution and resource waste.
