Abstract
The utility model discloses an overcharge-resisting lithium ion battery, which comprises a lithium ion battery core, an anode terminal and a cathode terminal, and is characterized in that the overcharge-resisting lithium ion battery also comprises a voltage stabilizing diode, an anode of the voltage stabilizing diode is connected with the cathode terminal of the overcharge-resisting lithium ion battery, and a cathode of the voltage stabilizing diode is connected with the anode terminal of the overcharge-resisting lithium ion battery. In the overcharge-resisting lithium ion battery, the voltage stabilizing diode is connected between the anode terminal and the cathode terminal of the lithium ion battery, and the anode and the cathode of the lithium ion battery are equivalently connected with each other directly when charging voltage is greater than reversed disruptive voltage of the voltage stabilizing diode, so that the damage on the battery caused by high voltage can be avoided effectively.
Description
Technical field
The utility model belongs to the lithium ion battery field, but especially relates to a kind of overcharging resisting, high safety-type lithium ion battery.
Background technology
Along with popularizing of digital products such as notebook computer, panel computer, mobile phone and improving constantly of performance, increasingly high in recent years to the capacity of lithium ion battery and the security performance requirement of these digital products.At present, mostly the battery of these products is that cobalt acid lithium or nickle cobalt lithium manganate are positive electrode.The battery advantage of this type manufacture of materials is to satisfy the requirement of these digital products to the battery high-energy-density.But the battery of this type material is in the process of charging, and possibility causes cell voltage to continue to rise owing to management system is out of control, thereby causes on fire, the blast of battery.IEC62133 overcharges the authentication requesting battery with 0.5C charging 5 hours, and battery is not on fire, do not explode, and present material system basically can't be through test.Therefore, seeking a kind of new lithium ion battery overcharging resisting solution has just become to press for.
Summary of the invention
The purpose of the utility model provides a kind of lithium ion battery with over-charge protective function.
Above-mentioned purpose is realized by following technical scheme: a kind of overcharging resisting lithium ion battery comprises core of lithium ion cell, anode pole piece and cathode pole piece; It is characterized in that: also comprise voltage stabilizing didoe, the positive pole of this voltage stabilizing didoe connects said cathode pole piece, and negative pole connects said anode pole piece.
Said core of lithium ion cell comprises the block core of lithium ion cell of flexible package or the cylindrical battery core of box hat.
The utility model is through connecting voltage stabilizing didoe between the positive pole of lithium ion battery and negative pole; When charging voltage during greater than the reverse breakdown voltage of voltage stabilizing didoe; Be equivalent to direct connection between the lithium ion battery positive and negative electrode, thereby can have effectively avoided big voltage damage that battery causes.
Description of drawings
The formation sketch map of the overcharging resisting lithium ion battery that Fig. 1 provides for embodiment.
Embodiment
As shown in Figure 1, the overcharging resisting lithium ion battery that present embodiment provides comprises core of lithium ion cell 11, anode pole piece 12, cathode pole piece 13 and is connected in parallel on the voltage stabilizing didoe 14 between the both positive and negative polarity.The positive pole of voltage stabilizing didoe 14 connects cathode pole piece 13, and negative pole connects anode pole piece 12.
It is understandable that core of lithium ion cell can not limit its formation and mechanism, for example can be the block core of lithium ion cell of flexible package or the cylindrical battery core of box hat.Equally, the structure of said anode pole piece and cathode pole piece is also unrestricted, for example normally used rectangular sheet pole piece.In addition, choosing of voltage stabilizing didoe is that actual characteristic according to battery is selected.In the present embodiment, battery is GPS063093/1300mAh, and positive electrode is LiCoO
2, negative material is a Delanium, electrolyte is LiPF
6The common electrolyte of/EC+PC+EMC, the voltage stabilizing didoe model of employing is 2CW22, puncture voltage is 4.5V, reverse current≤1 μ A, maximum stable electric current 660mA.Overcharge experimental technique by IEC62133 and test (the 650mA electric current continues charging 300min).After charging voltage reached 4.5V, the battery voltage no longer rose, and battery is not on fire, do not explode, and can overcharge authentication through IEC62133.
The overcharging resisting lithium ion battery that present embodiment provides is through a parallelly connected voltage stabilizing didoe between positive/negative plate; And the disruptive critical voltage of choosing voltage stabilizing didoe is consistent with the upper limit charging voltage of battery, and when charging voltage during less than the upper limit charging voltage of core of lithium ion cell, diode is in closed condition; Charger charges to battery; Battery is in a safe condition, and when charging voltage met or exceeded core of lithium ion cell upper limit charging voltage, voltage stabilizing didoe is switched on charger to be stopped battery being charged; Electric current passes through from voltage stabilizing didoe, thereby realizes the purpose of lithium ion battery overcharging resisting.
