Description
Technical field
The present invention relates to battery charging field, specifically a kind of lithium battery method for measuring charged.
Background technique
It by lithium metal or lithium alloy is negative electrode 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.With the development of science and technology, present lithium battery has become mainstream, and lithium battery is substantially
Two classes: lithium metal battery and lithium ion battery can be divided into.Lithium ion battery does not contain the lithium of metallic state, and is that can charge
's.5th generation product lithium metal battery of rechargeable battery was born in 1996, safety, specific capacity, self-discharge rate and property
Energy price ratio is superior to lithium ion battery.Since the high-tech of its own requires limitation, there was only the public affairs of a few countries now
Department is producing this lithium metal battery.
Lithium cell core, which is crossed, is charged to voltage higher than after 4.2V, starting to generate side effect.Overcharged voltage is higher, risk also with
It is higher.After lithium cell voltage is higher than 4.2V, remaining lithium atom quantity is less than half in positive electrode, and memory location often can at this time
It collapses, battery capacity is allowed to generate permanent decline.If continuing to charge, since the memory location of cathode has been already filled with lithium original
Son, subsequent lithium metal can be piled up in negative electrode material surface.These lithium atoms can by negative terminal surface toward lithium ion Lai direction it is long
Ingotism out.The crystallization of these lithium metals can keep positive and negative anodes short-circuit across diaphragm paper.Sometimes battery is just first before short circuit occurs
Explosion, this is because the materials such as electrolyte can crack generation gas in the process that overcharges, so that battery case or pressure valve blow-up are broken
It splits, oxygen is allowed to enter to react with the lithium atom for being deposited in negative terminal surface, and then explode.
Therefore, when lithium battery charges, have to setting upper voltage limit, can just combine service life of battery, capacity,
And safety.The optimal charging voltage upper limit is 4.2V.Lithium cell will also have lower voltage limit when discharging.When battery core voltage is lower than
When 2.4V, some materials can start to be destroyed.Again due to batteries self-discharge, putting more long voltage can be lower, therefore, when electric discharge most
2.4V is not put into well just to stop.During lithium battery discharges into this section of 2.4V from 3.0V, the energy discharged only accounts for battery capacity
3% or so.Therefore, 3.0V is an ideal discharge cut-off voltage.When charge and discharge, in addition to the limitation of voltage, the limit of electric current
System also has its necessity.When electric current is excessive, lithium ion has little time to enter memory location, can be gathered in material surface.
The measure of the overshoot explosion of protection lithium battery has much now, but we can attempt to solve from another angle
Certainly this problem, such as from charging plug.
