Description
Technical field
The present invention relates to technical field of lithium batteries more particularly to a kind of perfect heat-dissipating and explosion-proof lithium batteries.
Background technology
" lithium battery ", be it is a kind of by lithium metal or lithium alloy be negative material, the battery using non-aqueous electrolytic solution.By
It is very active in the chemical characteristic of lithium metal so that processing, preservation, the use of lithium metal, 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 battery has become mainstream.Lithium, atomic number
Number 3, atomic weight 6.941 are most light alkali metal elements.
Lithium cell core, which is crossed, is charged to voltage higher than after 4.2V, starting to generate side effect.Overcharged voltage is higher, it is dangerous also with
It higher.After lithium cell voltage is higher than 4.2V, remaining lithium atom quantity often can less than half, at this time memory location in positive electrode
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 material surface.These lithium atoms can by negative terminal surface toward lithium ion Lai direction it is long
Go out ingotism.The crystallization of these lithium metals can make positive and negative anodes short-circuit through diaphragm paper.Sometimes battery is just first before short circuit occurs
Explosion, this is because generation gas can be cracked in materials such as the process that overcharges, electrolyte so that battery case or pressure valve blow-up are broken
Split, allow oxygen enter and be deposited in negative terminal surface lithium atom reaction, and then explode.Therefore, when lithium battery charges, have to set
The constant voltage upper limit can just take into account service life, capacity and the security of battery simultaneously.The optimal charging voltage upper limit is
4.2V.Lithium cell will also have lower voltage limit when discharging.When battery core voltage is less than 2.4V, portion of material can start to be destroyed.Again
Due to batteries self-discharge, putting more long voltage can be lower, and therefore, when electric discharge had better not be put into 2.4V and just stop.Lithium battery from
During 3.0V discharges into 2.4V this section, the energy discharged only accounts for 3% or so of battery capacity.Therefore, 3.0V is one preferable
Discharge cut-off voltage.During charge and discharge, except the limitation of voltage, the limitation of electric current also has its necessity.When electric current is excessive, lithium ion comes
Not as good as into memory location, material surface can be gathered in.After these lithium ions obtain electronics, lithium atom knot can be generated in material surface
Crystalline substance, this with overcharge, danger can be caused.Just in case battery case ruptures, will explode.Therefore, to the guarantor of lithium ion battery
Shield, will at least include：The charging voltage upper limit, discharge voltage lower limit and upper current limit three.In general lithium battery group, except lithium
Outside battery, can all there be a piece of protection board, this piece protection board is mainly just to provide this three protections.It, must during cell system design
Must to overcharging, cross put, with overcurrent twice electronic protection is provided respectively.It charges after protection board is taken away, if battery can explode
It is bad with regard to representing design.Although the above method provides twice protection, but since consumer is after charger breaks down, Chang Huimai
Non-original factory charger charges, and charger dealer, based on cost consideration, often takes away charge controller, to reduce cost.Knot
Fruit, bad money drives out good money, occurs many chargers inferior on the market.This so that it is also most heavy to overcharge protection to lose first
One of the defence line wanted.And it is the most important factor for causing battery explosion to overcharge, therefore, charger inferior can deserve to be called electricity
The arch-criminal of pond explosive incident.Certainly, and not all battery system is all using the scheme of as above figure.In some cases, battery
Also the design of charge controller is had in group.
But this three of protection board protection be clearly it is inadequate, it is also necessary to the perfect heat-dissipating of lithium battery and its outside
Portion configures explosion-protection equipment, if the safeguard procedures of electronics all have failed, when explosion will occur, can be reduced by explosion-protection equipment
Explosion hazard is minimum so as to which the damage of generation be reduced to.
