Abstract
A kind of lithium titanate and ternary lithium composite battery, including housing, inner chamber is provided with the housing, lithium titanate battery and ternary lithium battery are provided with the inner chamber, the lithium titanate battery and ternary lithium battery share same lithium battery diaphragm, anode and negative electrode are respectively equipped with lithium titanate battery and ternary lithium battery, wherein 2 anodes are connected, negative electrode disconnects in not discharge and recharge；Because lithium titanate battery is different with the voltage of ternary lithium battery, for avoid two kinds of batteries because potential difference when idle inside invalid electric discharge, design and connect anode, negative electrode is disconnected；Only charge or discharge when, by control system just negative electrode is connected.The fast charging and discharging characteristic that the present invention can have using the superior material structure of lithium titanate battery, solve the slow defect of ternary charging and discharging lithium battery, the low defect of lithium titanate battery energy density is solved using the high energy storage characteristic of ternary lithium battery, the security and weatherability of ternary lithium battery can be also improved simultaneously, is increased the service life.
Description
Technical field
The present invention relates to technical field of lithium batteries, and in particular to a kind of lithium titanate and ternary lithium composite battery.
Background technology
The advantage of lithium titanate battery：1st, can soon it be discharged with charging quickly (6~10 points fully charged)；2nd, missing of ignition not explosion safety
Performance is high；3rd, long lifespan, can be recycled 30,000 times, 10~15 years life-spans；4th, weather resisteant is good, low temperature to subzero 50 DEG C, high temperature 60
℃.Shortcoming：Energy density is low.
The advantage of ternary lithium battery：Energy density is high.Shortcoming：Charging is unrestrained (filling soon 1 hour, trickle charge 10 hours), circulation time
Number is few, and short life (3~5 years) is not low temperature resistant.
It is technical problems to be solved in this application how two kinds of batteries to be carried out into mutual supplement with each other's advantages.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of capacity greatly, and electric discharge is fast, the lithium titanate of long lifespan and three
First lithium composite battery.
The technical problems to be solved by the invention are realized using following technical scheme：
Inner chamber is provided with a kind of lithium titanate and ternary lithium composite battery, including housing, the housing, is set in the inner chamber
Lithium titanate battery and ternary lithium battery are equipped with, the lithium titanate battery and ternary lithium battery share same lithium battery diaphragm, in titanium
Anode and negative electrode are respectively equipped with acid lithium battery and ternary lithium battery, wherein 2 anodes are connected, negative electrode breaks in not discharge and recharge
Open；Because lithium titanate battery is different with the voltage of ternary lithium battery, for avoid two kinds of batteries because potential difference when idle inside
Invalid electric discharge, design connects anode, and negative electrode is disconnected；Only charge or discharge when, by control system just negative electrode is connected.
Further, the inner walls scribble anticorrosive paint.
Further, the lithium battery diaphragm is made using vertically and horizontally stretching technique, its rigidity, flatness, tensile strength
It is good with opening.
The beneficial effects of the invention are as follows：The quick charge and discharge that the present invention can have using the superior material structure of lithium titanate battery
Electrical characteristics, solve the slow defect of ternary charging and discharging lithium battery, and lithium titanate battery energy is solved using the high energy storage characteristic of ternary lithium battery
The low defect of metric density, while can also improve the security and weatherability of ternary lithium battery, increases the service life.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Embodiment
In order that the technical means, the inventive features, the objects and the advantages of the present invention are easy to understand, tie below
Conjunction is specifically illustrating, and the present invention is expanded on further.
Embodiment 1
As shown in figure 1, a kind of lithium titanate and ternary lithium composite battery, including housing 1, the housing 1 is interior to be provided with inner chamber,
Lithium titanate battery 2 and ternary lithium battery 3 are provided with the inner chamber, the lithium titanate battery 2 and ternary lithium battery 3 share same
Lithium battery diaphragm 4, anode 5 and negative electrode 6 are respectively equipped with lithium titanate battery 2 and ternary lithium battery 3, wherein 2 anodes 5 are connected
Connect, in not discharge and recharge, negative electrode disconnects；Because the voltage of the ternary lithium battery 3 of lithium titanate battery 2 is different, for avoid two kinds of batteries because
Potential difference when idle inside invalid electric discharge, design and connect anode 5, negative electrode 6 is disconnected；Only charge or discharge when, lead to
Control system is crossed just to connect negative electrode 6.The inwall of housing 1 scribbles anticorrosive paint, and the lithium battery diaphragm 4 is to use to draw in length and breadth
Stretching process is made, and its rigidity, flatness, tensile strength and opening are good.
The application lithium titanate and ternary lithium composite battery proving and comparisom data are shown in Table 1；
Table 1：
The general principle and principal character and advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the simply explanation described in above-described embodiment and specification is originally
The principle of invention, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
