Description
Technical field
The present invention relates to battery detection equipment fields, and in particular to a kind of glove box.
Background technology
Lithium ion battery has two class of liquid lithium ionic cell (LIB) and polymer Li-ion battery (PLB) at present.Wherein,
Liquid lithium ionic cell refers to the secondary cell that Li+ inlaid schemes are positive and negative electrode.Anode is using lithium compound-cobalt acid lithium, manganese
Sour lithium, cathode use lithium-carbon intercalation compound.Lithium ion battery is since operating voltage is high, small, light weight, energy are high, nothing
Memory effect, pollution-free, self discharge is small, has extended cycle life, and is the ideal energy carrier of 21 century development.
And demand of the different positive electrode systems to electrolyte content is mutually variant, the lithium cobaltate cathode system electricity of high-density
Pond is in the battery core of same size, capacity highest, and electrolyte demand is minimum；And the LiMn2O4 and ferric phosphate of low tapped density
Lithium anode system battery, capacity is relatively low, and electrolyte demand is maximum.
The internal resistance of battery is reduced with the increase of electrolyte content, and capacity increases with the increase of electrolysis amount.Electrolyte
When measuring very few, the internal resistance of cell is big, and capacity is low；When electrolyte content reaches a certain amount of, internal resistance and capacity tend towards stability.
Electrolyte content influences significantly the cycle performance of battery and overcharge resistant ability, when electrolyte content is excessive very few,
Cycle performance and security performance are all poor.
Most of lithium battery is used with resistance, and resistance, voltage, internal resistance can just match use in a certain range, to electricity
It is higher to solve liquid homepage precision prescribed, finds that electrolyte has bubble during injection process and use, leads to electrolyte precision not
It is enough, so bubble must be improved to improve fluid injection precision.
For lithium battery in normal fluid injection production process, electrolyte can mix part bubble, cause injecting electrolytic solution amount unstable
It is fixed, there are equipment vendors to solve electrolyte bubble by the way of vacuum suck-back in fluid reservoir before, but electrolyte is to pass through
It crosses fluid reservoir de-bubble and then by pipeline, topping-up pump completes fluid injection action, can continue to find bubble in pipeline and inject electricity
Pond.So just bubble can not achieve the desired results fluid reservoir.
Invention content
In view of the defects and deficiencies of the prior art, the present invention intends to provide a kind of glove boxes, use the glove box
When carrying out injecting electrolytic solution, not only removal waste fluid is convenient, reduces Pipe installing, easy to maintenance, and has effectively removed electrolyte
In bubble, improve fluid injection precision.
To achieve the above object, the present invention is using following technical scheme：
A kind of glove box, including liquid-feeding tube, anolyte storage tank, inlet tube, glove box pipeline, battery, topping-up pump, gas-liquid
The input end of current divider, exhaust pipe and gas outlet, liquid-feeding tube and anolyte storage tank connects, the outlet end of anolyte storage tank with
Inlet tube connects, and is provided with glove box pipeline below anolyte storage tank, glove box duct bottom is provided with multiple batteries, battery
It is electrically connected with topping-up pump, inlet tube is connect with Gas and liquid flow diverter, the row of being connected between Gas and liquid flow diverter and anolyte storage tank
The top of tracheae, anolyte storage tank is connected with gas outlet.
Above-mentioned glove box adds a Gas and liquid flow diverter, in injection process, since electrolysis liquid proportional is more than bubble, and
Holding vessel position is higher, during electrolyte use, free electrolyte and bubble (bubble floating) is carried out using proportion, to reach
To the bubble eliminated in electrolyte, the effect of fluid injection precision is improved.Secondly, air floats in electrolyte current divider, avoids
Bubble flows into topping-up pump.
Preferably, the inlet tube is provided with ball valve at Gas and liquid flow diverter.When equipment breaks down, it can close nearby
Corresponding ball valve is closed, repair is facilitated.
After adopting the above technical scheme, the present invention has the beneficial effect that：Glove box of the present invention, in injection process, due to electricity
Solve liquid proportional and be more than bubble, and holding vessel position is higher, during electrolyte use, using proportion carry out free electrolyte and
Bubble (bubble floating) improves the effect of fluid injection precision to reach the bubble eliminated in electrolyte.Secondly, electrolyte point
It flows air in device to float, bubble is avoided to flow into topping-up pump.Since this glove box is added with Gas and liquid flow diverter so that the device is not only
Removal waste fluid is convenient, reduces Pipe installing, easy to maintenance, and has effectively removed the bubble in electrolyte, improves fluid injection essence
Degree.
Description of the drawings
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technology description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention without having to pay creative labor, may be used also for those of ordinary skill in the art
With obtain other attached drawings according to these attached drawings.
Fig. 1 is the structural schematic diagram of the present invention；
Fig. 2 is the component refinement figure of Fig. 1.
