Abstract
The utility model provides a kind of electrodes of lithium-ion batteries compaction apparatus, including hard alloy mold and cemented carbide base, the hard alloy mold are located at the top of cemented carbide base, and the bottom of the hard alloy mold is provided with multiple briquettings.This pole piece compaction apparatus as pressed material, can hold the sufficiently large pressure of the offers such as hydraulic press using hard alloy steel.The electrodes of lithium-ion batteries compaction apparatus is avoided that due to pole piece extension effect caused by line style contact compacting by the way of flat board compacting.During compacting, with pole piece iterative method, many places can be realized while be compacted and the repetition compacting that exists together, electrodes of lithium-ion batteries compaction quality is effectively guaranteed, avoids the operation repeatability to roller compaction, improve production efficiency.
Description
Technical field
The utility model belongs to secondary cell field, and in particular to a kind of preparation facilities of battery pole piece.
Background technology
In recent years, lithium ion battery is used widely in fields such as household electrical appliance, the vehicles, science and techniques of defence, and
And further go deep into the electrification epoch, its application field has more wide prospect.
For lithium ion battery in manufacturing process, compacted density has large effect to battery performance.Compacted density and capacity,
Efficiency, internal resistance, and cycle performance of battery have close relationship.In the condition that battery specifications model is fixed, process conditions are certain
Under, compacted density is bigger, and the capacity of monomer lithium ion battery is higher, and the unit integrated cost of battery is also lower.So compacting is close
Degree is also seen as one of principal element of battery material energy density.Therefore improve pole piece compaction density, be it is current improve lithium from
The important channel of sub- battery energy density.
In current production, industry mainly improves the compacted density of battery pole piece using the method to roller compaction.This method
Although can meet the basic demand of compacting, in two pairs of rollers compacting process, double roller is to being linear contact lay caused by battery pole piece.It is this
Compacting mode easily makes pole piece that extension effect occur, and this thickness and the uniformity to pole piece is also easy to produce ill effect.Industry is usual
It is using increasing twin rollers roll neck, to reduce the ill effect that linear contact lay compaction band comes.But the increasing of double roller diameter, compacting
Equipment cost can increase substantially.Therefore, for current electrodes of lithium-ion batteries compacting process problems faced, there is an urgent need to set
Count it is a kind of it is simple in construction, easy to operate, price is cheap, can meet the new type lithium ion battery of actual lithium battery pole slice compacting needs
Pole piece compaction apparatus.
Utility model content
Part in view of the shortcomings of the prior art, the purpose of this utility model are to propose a kind of simple in construction, operation side
Just, price is cheap, can meet the new type lithium ion battery pole piece compaction apparatus of practical lithium-ion pole piece compacting needs.
The concrete technical scheme for realizing the utility model purpose is：
A kind of electrodes of lithium-ion batteries compaction apparatus, including hard alloy mold and cemented carbide base, the hard
Alloy mold is located at the top of cemented carbide base, and the bottom of the hard alloy mold is provided with multiple briquettings.
Further, the bottom of the hard alloy mold is provided with 3-5 rectangle briquetting, and the width of the briquetting is
1-30cm, adjacent briquetting spacing are 2-50cm.
Preferably, the width of the briquetting is 5-15cm, a length of 10-100cm, and adjacent briquetting spacing is 10-20cm.
The beneficial effects of the utility model are：
1, the pole piece compaction apparatus, as device materials, can hold the sufficiently large of the offers such as hydraulic press using hard alloy steel
Pressure.The electrodes of lithium-ion batteries compaction apparatus is avoided that due to caused by line style contact compacting by the way of flat board compacting
Pole piece extension effect；
2, with pole piece iterative method, many places can be realized while be compacted and the repetition compacting that exists together, be effectively guaranteed lithium from
Sub- battery pole piece compaction quality, the operation repeatability to roller compaction is avoided, improves production efficiency；
3, apparatus structure design is simple, and cost is extremely low, is easy to safeguard, reduces equipment purchase and maintenance cost, and then
Production cost input is reduced, adds economic benefit.
