And preparation method thereof.
Background technique
Lithium ion battery because monomer battery voltage is high, energy and power density are big, have extended cycle life the advantages that, already take up
The leading position in secondary cell market, becomes most important electric energy storage device.The promotion of performance of lithium ion battery, mainly takes
Certainly in the development of electrode material technology.In existing commercialized lithium ion battery, negative electrode material is main or traditional
Graphite material, lower theoretical capacity (372 mAh/g) seriously limit the further promotion of lithium ion battery energy density.
Zinc oxide is as a kind of novel negative electrode of lithium ion battery alternative materials, and theoretical capacity is about 900 mAh/g, far
Higher than graphite material.Although high capacity advantage allows it to show very big application potential, commercial applications do not have always
It realizes.There are two serious problems: (1) head of zinc oxide when this is primarily due to zinc oxide directly as negative electrode material use
Secondary coulombic efficiency is low.The initial coulomb efficiency of regular oxidation zinc powder powder electrode material is generally below 50%, this is because zinc oxide
Discharging product for the first time (lithia and solid electrolyte membrane) cannot be decomposed completely during subsequent initial charge, charging is anti-
It should be not thorough.(2) cycle performance of zinc oxide is low.Regular oxidation zinc powder powder electrode material often holds at circulation initial stage
Amount makes particle this is because zinc oxide material there are serious volume expansion and is shunk in charge and discharge process with regard to sharp-decay
Rapid dusting and fail.
In order to improve the chemical property of zinc oxide negative electrode material, the common conventional means of researcher are nanostructures
Change.This means tend to the cyclical stability of reinforcing material, but to the raising of material initial coulomb efficiency without positive effect.It receives
Rice structural material generally has high specific surface area, often leads to the generation of more side reactions, is unfavorable for coulomb effect for the first time
The raising of rate.
Summary of the invention
It is a kind of for negative electrode of lithium ion battery the invention aims to provide, there is high initial coulomb efficiency, reversible appearance
The compound micron bar material of zinc oxide/nickel and preparation method thereof that amount and cyclical stability are all obviously improved.
A kind of preparation method of the compound micron bar electrode material of zinc oxide/nickel, its step are as follows:

(2) step (1) resulting precursor powder is calcined in hydrogen argon mixing reducing atmosphere, calcination temperature be 300 ~
500 oC, calcination time are 0.5 ~ 3 h, obtain the compound micron bar electrode material of zinc oxide/nickel.
In the compound micron bar electrode material of zinc oxide/nickel, zinc oxide micron rods are matrix, and the length is 10 ~ 15 μ
M, diameter are 2 ~ 3 μm, and shared mass fraction is 90% ~ 95%;Nano nickel particles are dispersed in zinc oxide micron rods matrix, matter
Measuring score is 5% ~ 10%.
In the combination electrode material, the introducing of high activity metal nano nickel particles has the chemical property of material aobvious
The humidification of work, compared with regular oxidation zinc powder body material, the combination electrode material has the advantages that in following performance:
One, the metallic nickel nano granule in the composite material material is made by hydrogen reducing, has high electro-chemical activity,
During the charging process, it after can discharging for the first time with zinc oxide lithia generated occur to electrochemically convert reaction that (it is substantially
The storage lithium mechanism of nickel oxide material), the extent of reaction that lithia participates in charging reaction is significantly increased, charging capacity is improved;It is also
With high catalytic activity, during the charging process, can by discharge process for the first time because side reaction generate solid electrolyte
Film decomposes under its catalytic action, can also contribute a part of charging capacity.The raising of material initial charge capacity also results in it
The increase of initial coulomb efficiency, initial coulomb efficiency of the combination electrode material at 0.1 C is 70% ~ 80%, reversible for the first time
Capacity is 800 ~ 900 mAh/g.
Two, uniformly compound between zinc oxide micron rods matrix and score nano nickel particles in the combination electrode material, no
Material conductivity only can be enhanced, mitigate electrode polarization, the structural strength of micron bar particle can also be enhanced, inhibit material anti-
Because of dusting caused by volume constantly dilation during multiple lithiumation/go lithiumation, so as to improve material circulation stability.
Reversible capacity conservation rate after combination electrode material recycles 100 times at 0.1 C is 70% ~ 75%.
Three, in the combination electrode material, zinc oxide micron rods are along<001>direction preferential growth, a large amount of (001) interplanars
For gap in the exposure of micron bar side, its spacing is maximum, and lithium ion passes in and out resistance minimum, therefore combination electrode material enhances its high power
Rate charge-discharge performance.
Four, the combination electrode material because its particle size be micron order, the density of powder body material can be improved, effectively increase
The volume and capacity ratio of made electrode.The rodlike pattern of particle can shorten the diffusion path of lithium ion, efficiently solve large scale
The problem of particle increases electrode polarization because of ion diffusion path length.
