Description
Technical field
The invention belongs to lithium battery new energy field, mainly a kind of new method of high-homogenized production lithium battery material.
Background technology
Traditional anode material of lithium battery be presoma and lithium source after metering, mixing is ground, by certain
Think uniformly mixed after the mixing of time, then calcined, prepare anode material of lithium battery.
Above-mentioned production process is in following problem：1st, presoma and lithium source are mixed by lapping mode, it is difficult to ensure that mixed
Close uniformly, the difference be easy to causeing between batch ultimately results in the difference between lithium battery product batches, and homogeneity is bad；2、
Presoma and the particle diameter of lithium source are limited by upstream materials, can not accurately control, and distribution is too wide, and cause to be formed between the two has
Effective component content is not high, and lithium ion does not make full use of, and causes the reduction of specific capacitance amount；How lithium battery is efficiently being realized just
Homogenization, the high-lithium ion utilization ratio of pole material are a problems.
The content of the invention
It is an object of the invention to overcome the shortcomings of the prior art, and provide a kind of high-homogenized production lithium battery material
The new method of material.
The purpose of the present invention is by following technical solution to complete.It is this it is high-homogenized production lithium battery material it is new
Method, this method comprises the following steps：By lithium battery tertiary material precursor and lithium source after accurate measurement, pass through mixer
It is sufficiently mixed, is then crushed again by airslide disintegrating mill, the material of crushing is put into mixing again after bag filter is collected
Secondary mixing is carried out in machine, so as to be uniformly dispersed, among the lithium battery tertiary cathode material that size tunable, quality are homogeneous
Body, the intermediate are calcined again, and lithium battery tertiary cathode material is made.
Preferably, the mixer is various various forms of mixers such as cone-type mixer or colter mixer,
Generally require volume larger, the material quantity of single mixing is big, it is possible to reduce batch size, improves the overall uniformity.
Preferably, mixed raw material is crushed by airslide disintegrating mill, while play the role of mixing.Air-flow powder
Broken machine can be the various types of pulverizer such as disc type airslide disintegrating mill, fluidized bed air flow crusher, and the present invention is preferably
Fluidized bed air flow crusher.
Preferably, the lithium source includes lithium hydroxide or lithium carbonate.
Preferably, the control of crushing process product cut size is at 5-15 microns.
Preferably, being sufficiently mixed by mixer, incorporation time is in 30-60min.
Beneficial effects of the present invention are：The present invention substitutes mechanical lapping etc. by increasing mixer, with airslide disintegrating mill and sets
It is standby, in the case where not increasing operation difficulty, the high uniformity of product is realized, and can strictly control particle diameter at one
In relatively narrow scope, the utilization rate of lithium ion is improved, improves battery capacity.
Brief description of the drawings
Fig. 1 is the flow diagram of the present invention.
Embodiment
Detailed introduction is done to the present invention below in conjunction with attached drawing：
As shown in Figure 1, the new method of this high-homogenized production lithium battery material, this method comprises the following steps：By lithium
The lithium source such as battery ternary material precursor and lithium hydroxide or lithium carbonate is fully mixed by mixer after accurate measurement
Close, incorporation time 30-60min.Then the raw material after being homogenized is crushed by airslide disintegrating mill again, while plays mixing
Act on, control product cut size in crushing process, size controlling is at 5-15 microns.The material of crushing after bag filter is collected again
It is put into mixer and carries out secondary mixing, so as to is uniformly dispersed, the lithium battery tertiary cathode material that size tunable, quality are homogeneous
Expect intermediate, which is calcined again, and lithium battery tertiary cathode material is made.
Embodiment：95kg ternary material precursors accurately are weighed, 45 kilograms of Lithium hydroxide monohydrates, are poured into colter mixer
In, 35min is mixed, is sent in disc type airslide disintegrating mill and is crushed after mixing, crushes pressure 0.75mPa, is crushed
After the completion of carry out secondary mixing pouring into colter mixer, Muffle furnace is sent into after the completion of mixing in batches and is calcined, is made three
First positive electrode.
It is understood that it will be understood by those skilled in the art that technical scheme and inventive concept are subject to
The protection domain of appended claims of the invention should all be belonged to replacement or change.
