Description

Lithium ion battery multi-element composite positive pole material and preparation method thereof
Affiliated field
The present invention relates to lithium ion battery with novel anode material and preparation thereof, relate to a kind of multi-element composite positive pole material and preparation method or rather, be used for lithium dynamical battery.Belong to field of energy source materials.
Technical background
At present, along with the fast development of portable electric appts such as mobile phone, digital camera, notebook computer, market is increasing to the demand of high power, high energy density cells.Lithium ion battery is the battery that voltage is the highest, energy density is maximum in the battery of practicability up to now, has bright development prospect.
In commercial at present anode material for lithium-ion batteries, lithium cobalt oxygen (LiCoO 2) rely on excellent cycle performance (reversible discharging and recharging greater than 500 times) and bigger discharge capacity (140mAh/g) and high discharge platform (3.9V/Li) to occupy the market share greater than 95%.But LiCoO 2Following shortcoming is also arranged: the one, cobalt belongs to rare metal, and the reserves in the earth's crust are few, so the price height, and cobalt is poisonous simultaneously, and is unfriendly to environment; The 2nd, LiCoO 2Thermal stability very poor, under the degree of depth discharges and recharges condition (charging cut-ff voltage greater than 4.2V) decomposition reaction easily takes place generates a large amount of heat, cause the overheated even blast of battery, influenced its application in macrocell (as electrokinetic cell etc.); The 3rd, LiCoO 2The Reversible Cycle capacity about 140mAh/g, available actual capacity has only about 130mAh/g.Therefore the positive electrode that seek cheap, environmental friendliness, has more high power capacity, a better thermal stability has important practical value to the development of lithium ion battery.
Since the eighties of last century the nineties, the low eco-friendly lithium nickel oxygen (LiNiO simultaneously of price 2), lithium manganese oxygen (LiMn 2O 4) be considered to most possibly to substitute LiCoO always 2Material.Nearly ten years studies show that, LiNiO 2The layer structure poor stability, stoichiometric LiNiO 2Be difficult at low temperatures synthesize, and the mixing occupy-place of lithium nickel can take place under the high temperature synthesis condition; Can synthesize LiNiO by accurate condition control (in oxygen atmosphere, 750 ℃ roasting temperature 24 hours) 2, it has higher initial capacity (initial charge capacity reaches 200mAh/g), but cycle performance is poor especially, and capacity promptly is lower than LiCoO after 10 circulations 2The LiMn that price is lower 2O 4Synthetic simple, but its capacity little (120mAh/g), and more fatal is, because the manganese ion of high price is easy to react LiMn with electrolyte under higher temperature 2O 4High temperature (50 ℃) cycle performance extreme difference.Therefore in the past several years, numerous electrochemical researchers have put into LiNiO with main energy 2, LiMn 2O 4Doping vario-property research in.In view of the character of nickel and cobalt close, LiCoO simultaneously 2Cyclical stability be better than LiNiO 2, therefore adopt the part cobalt to replace nickel to improve LiNiO 2The electrochemistry cycle performance approved by most researchers.From existing bibliographical information and this breadboard result of the test, laboratory scale LiNi xCo 1-xO 2The preparation of material has obtained success, LiNi xCo 1-xO 2With the sacrifice capacity is cost, has increased substantially the cycle performance of self, but still is lower than LiCoO 2LiNi xCo 1-xO 2Preparation technology compare LiCoO 2Complexity is also more done the requirement of raw material, causes production cost to rise, simultaneously LiNi xCo 1-xO 2Discharge potential than LiCoO 2About low 100mV, this has limited LiNi xCo 1-xO 2Large-scale industrial production.Another kind of positive electrode LiMn 2O 4Preparation technology ripe.Study on the modification mainly concentrates on the cycle performance that improves material by the doping of nickel, cobalt, rare earth metal, and document shows that the research of this respect has obtained certain result, but because LiMn 2O 4Molecular weight big, its theoretical specific capacity is on the low side (148mAh/g), being doomed it can't be at the market of lithium ion battery maximum one battery of mobile phone field and LiCoO 2Competition.Though can improve LiMn by modification 2O 4Normal-temperature circulating performance, but cycle performance under higher temperature does not still have the raising of matter, thereby can't be used as electrokinetic cell, further studies still in exploration at present.
