Description
Technical field
The present invention relates to a kind of high power capacity ferric flouride complex lithium electricity positive electrode manufacture method technical field.
Background technology
Lithium rechargeable battery have volume, weight energy than high, voltage is high, self-discharge rate is low, memory-less effect, have extended cycle life, the high absolute advantage of power density, have more than 30,000,000,000 dollar/year shares in portable power source market, the whole world and increase gradually with the speed more than 10% at present.Particularly in recent years, along with petering out of fossil energy, the new forms of energy such as solar energy, wind energy, biomass energy are increasingly becoming the alternative of traditional energy, and wherein wind energy, solar energy have intermittence, use substantial amounts of energy-storage battery for meeting lasting supply of electric power needs simultaneously；The urban air-quality problem that vehicle exhaust brings is day by day serious, and instant stage has been arrived in vigorously advocating and developing of electric motor car (EV) or hybrid electric vehicle (HEV)；These demands provide lithium ion battery explosive growth point, also the performance of lithium ion battery are had higher requirement simultaneously.
The raising of the capacity of anode material for lithium-ion batteries is the primary goal that scientific and technical personnel study, and the research and development of high power capacity positive electrode can alleviate that current Li-ion batteries piles volume is big, heavy weight, price are high-leveled and difficult to meet high power consumption and the situation of high-power equipment needs.But since lithium ion battery commercialization in 1991, the actual specific capacity of positive electrode is hovered all the time between 100-180mAh/g, positive electrode specific capacity is low has become as the bottleneck promoting lithium ion battery specific energy.The positive electrode of the most commonly used practicality of lithium ion battery commercial at present is LiCoO2, the theoretical specific capacity of cobalt acid lithium is 274mAh/g, and actual specific capacity is between 130-140mAh/g, and cobalt is strategic materials, expensive and have bigger toxicity.Therefore in recent years, the research worker of countries in the world is devoted to the research and development of Olivine-type Cathode Material in Li-ion Batteries always, up till now, the lithium ion cell positive filtered out is up to tens of kinds, but really has potential commercial applications prospect or the positive electrode that is already present on market very few really.Such as lithium manganate having spinel structure LiMn2O4, it is less costly, is easier preparation, and security performance is also relatively good, but capacity is relatively low, and theoretical capacity is 148mAh/g, and actual capacity is at 100-120mAh/g, and this material capacity circulation holding capacity is not good, and under high temperature, capacity attenuation is quickly, Mn3+John-Teller effect and dissolving in the electrolyte annoying research worker for a long time.The LiNiO of layer structure2And LiMnO2Although having bigger theoretical specific capacity, respectively 275mAh/g and 285mAh/g, but they prepare extremely difficult, poor heat stability, and cyclicity is very poor, and capacity attenuation is quickly.And current progressively business-like LiFePO4 LiFePO4Cost is low, Heat stability is good, environmental friendliness, but its theoretical capacity about only has 170mAh/g, and actual capacity is at about 140mAh/g [ChunSY, BlokingJT, ChiangYM, NatureMaterials, 2002,1:123-128.].The positive electrode more than 200mAh/g specific capacity having market prospect at present only has lithium vanadate Li1+xV3O8, Li1+xV3O8Material can have and has even close to the capacity of 300mAh/g, but its electric discharge average voltage relatively low and in production process barium oxide often toxicity bigger.High lithium ratio is on positive electrode in recent years, particularly the high lithium of manganio manganese-nickel binary and manganio manganese-nickel-cobalt ternary solid solution system compares positive electrode, there is the cost of the Capacity Ratio more than 200mAh/g, higher heat stability and relative moderate and receive the concern of people, but performance under this material high magnification is very undesirable, limits its application [Young-SikHong, YongJoonPark in electrokinetic cell, etal., SolidStateIonics, 2005,176:1035-1042].
In recent years, FeF3Material enters the visual field of researcher owing to its capacity is high, the prices of raw materials are low.FeF3Material is different with the operation principle of conventional lithium ion battery positive electrode, all there is lithium ion and can embed or the space of deintercalation in traditional lithium ion cell positive and negative pole, and the lithium ion in electrolyte embeds between a positive electrode and a negative electrode back and forth and deintercalation and discharge as proposed " rocking chair " batteries such as Armand.And FeF3It is then a kind of transition material, namely in whole discharge process, FeF3There is following change [BadwayF, CosandeyF, PereiraN, etal., ElectrodesforLiBatteries, J.Electrochem.Soc., 2003,150 (10): A1318-A1327.]:
Li++FeF3+e→LiFeF3----(1)
LiFeF3+2Li++2e→3LiF+Fe-(2)
The Lithium-ion embeding of the first step and namely conventional lithium ion, in whole course of reaction, lattice does not have big change；And second is the displacement reaction of metal, parent lattice there occurs conversion completely.The theoretical capacity of the first step is 237mAh.g-1；Complete reaction can realize the conversion of 3 electronics, and namely the theoretical capacity of second stage is 474mAh.g-1；Total capacity is 711mAh.g-1；Although this material does not have clear and definite discharge platform, average discharge volt is also relatively low, but it is close to 800mAh.g-1Theoretical specific capacity be also that of obtaining investigation of materials personnel height attention.But, through such as Arai, Amatucci [BadwayF, PereiraN, CosandeyF, etal., J.Electrochem.Soc., 2003,150 (9): A1209-A1218.] etc. the research of scholar finds, its theoretical capacity major part be discharged not is an easy thing.First FeF3Electronic conduction ability excessively poor, simultaneously its lithium ion conductivity is also very low, and the product LiF after changing is electronic body, and the ability of conducting lithium ions is also very poor simultaneously, thus causing FeF3The available capacity that material can utilize is relatively low, and charging and discharging currents is little, and multiplying power property is poor；Polarization in charge and discharge process is comparatively serious, and charging/discharging voltage platform has a long way to go；Capacity holding capacity is not good, and along with the increase of discharge and recharge number of times, capacity attenuation is serious.About 50-100mAh.g can only be discharged research early stage-1Reversible capacity；Amatucci etc. improved its conductive capability by forming carbon/ferric flouride nano-complex (CMFNCs) with material with carbon element through long-time high-energy ball milling later, substantially increased its chemical property, and its discharge capacity can reach 200mAh.g-1Left and right [BadwayF, MansourA.N, PereiraN, etal., Chem.Mater., 2007,19 (17): 4129-4141.].But, material with carbon element attachment on positive electrode particle surface, mainly by physical absorption, constitutes complete carbonaceous conductive link more difficult.At this, as it was previously stated, the discharge voltage of this material is relatively low, effective energy density is not too outstanding；Finally, because FeF3Material is slightly soluble in cold water, so generally adopting the method for ethanol liquid phase to prepare, needs to use substantial amounts of ethanol in building-up process, and economy is not good.It is unsuitable in industrial applications.
Therefore, FeF is improved3The chemical property of positive electrode needs to seek a kind of method that can improve lithium ion conductivity and energy density, makes that preparation flow is simple as far as possible, cost is low, convenient and swift simultaneously, and this is to FeF3The development and application of positive electrode is particularly important.
