It is coated on Copper substrate.
It should be noted that described positive pole 4 has power supply 12 to be connected with load 13 with negative pole 6 by wire respectively.
This utility model reasonable in design, does not use the aqueous solution electrolysis of such as lead-acid accumulator or nickel-hydrogen accumulator
Liquid, but use organic electrolyte；In charging process, the lithium in positive pole is ionic condition, moves in the electrolytic solution, and is born
Carbonizable substance absorption in extremely；Electric discharge is then the back reaction of charging process；In this course of reaction, usual lithium is deposited with ionic forms
, the not lithium of precipitating metal state；Voltage is higher, and lightweight；The energy density of lithium-ions battery, power density is very
Height, has the biggest using value.
Dividing plate or title isolation diaphragm, its function plays the effect closed or block passage, generally uses polyethylene or poly-third
The micro-porous film of alkene material.So-called closedown or block function are that battery occurs that abnormal temperature rises, and block or block as ion
The pore of passage, makes accumulator stop discharge and recharge reaction.Dividing plate can effectively prevent the super-high-current caused because of external short circuit etc.
And make battery produce abnormal heating phenomenon.
Electrolyte is the organic electrolyte based on mixed solvent.In order to make the lithium salts of main electrolyte composition dissolve,
Must have high-dielectric constant, and have the solvent good with the lithium ion compatibility, that does not the most hinder that ion moves is low viscous
Organic solution is advisable, and in the operating temperature range of lithium-ions battery, it is necessary in liquid condition, freezing point is low, boiling point
High.Electrolyte has chemical stability for active substance, it is necessary to occur in good conformity discharge and recharge course of reaction is violent
Redox condition.
In order to ensure the safety in utilization of lithium-ions battery, typically by the control to external circuit or in accumulator
Inside is provided with the safety device that abnormal current cuts off.Even if so, being in use also possible to other reasons to cause electric power storage
The intrinsic pressure abnormal rising in pond, so, relief valve release gas, to prevent accumulator from rupturing.Relief valve is actually the most non-repairing
Compound fracturing diaphragm, once enters duty, and protection accumulator makes it quit work, is therefore the last protection of accumulator
Means.
Operation principle: lithium ion battery is actually a lithium ion concentration cell, positive and negative electrode is by two kinds of different lithiums
The intercalation compound structure of ion.During charging, Li+ embeds negative pole from positive pole deintercalation through electrolyte, and now negative pole is in rich lithium state, just
Pole is in lean lithium state；During electric discharge then on the contrary, Li+, from negative pole deintercalation, embeds positive pole through electrolyte, and positive pole is in rich lithium state, negative
Pole is in lean lithium state.The running voltage of lithium ion battery with constitute the dense of the Lithium-ion embeding compound of electrode itself and lithium ion
Spend relevant.Therefore, when charge and discharge cycles, there is " embedding-deintercalation " reaction in Li+ on both positive and negative polarity, Li+ just at both positive and negative polarity respectively
Between move back and forth.
Lithium battery has following characteristic in charging:
Half section the most before charging, voltage is gradually increasing；
2., after voltage reaches 4.2V, internal resistance changes, and voltage remains unchanged；
During the most whole, electricity is continuously increased；
4., close to when being full of, charging current can reach the least value.
Through years of researches, have found preferable charge control method:
1. trickle charge reaches final discharging voltage 2.7V；
2. use constant current to be charged, make voltage basically reach 4.2V.Safe current is less than 0.8C；
3. constant-current phase can reach the 80% of electricity substantially
4. transferring constant-voltage charge to, electric current is gradually reduced；
5., when electric current reaches less value (such as 0.05C), battery reaches full state.
The standardized element that this utility model uses all can commercially, shaped piece according to description and accompanying drawing
Record all can carry out customized, the concrete connected mode of each part all uses in prior art ripe bolt, rivet, weldering
The conventional means such as connecing, machinery, part and equipment all use in prior art, and conventional model adds that circuit is connected by existing
Connected mode conventional in technology, is not described in detail in this.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described.One's own profession
Skilled person will appreciate that of industry, this utility model is not restricted to the described embodiments, described in above-described embodiment and description
Principle of the present utility model is simply described, on the premise of without departing from this utility model spirit and scope, this utility model is also
