Description
Technical field
The present invention relates to the preparation field of lithium ion battery or lithium cell electrolytic salt used, particularly relate to a kind of preparation method of liquid di-oxalate lithium borate.
Background technology
Electrolytic salt is the important component part of lithium ion battery, and the cost of battery and performance are had to material impact, therefore it is study hotspot always.LiPF

2, claim again LiBOB) and the most noticeable.LiBOB structural formula is as follows:
LiBOB is coordination inner complex, and quadrature crystal belongs to Pnma point group.Decomposition temperature is up to 300 ℃, and thermal stability and safety performance are excellent.Can form stable SEI film at negative pole, avoid electrolytic solution to decompose in negative terminal surface, and then improve the cycle performance of battery.The electrolytic conductivity that adds LiBOB can reach 10ms/cm, meets the requirement of current commercially produced product completely.Because only containing lithium, carbon, oxygen, boron, containing toxic metal element, non-corrosiveness, has the feature of environmental protection.
The synthetic method of LiBOB mainly contains at present: liquid phase method and solid phase method; Liquid phase method can be divided into water system method, organic solvent method according to reaction medium, and wherein, water system method has the features such as environmental protection, economy, technique be simple, but the existence of water serious threat LiBOB, and it is more difficult in subsequent purification process, to dewater; It is reaction medium that organic solvent method adopts organic solvent, product moisture content less, but need a large amount of solvents, and cost is higher, complex process, and environment is had to pollution to a certain degree.Solid phase method, according to energy-provision way, can be divided into solid heating method, solid microwave method; Wherein, the advantage of solid heating method is not use any organic solvent, with low cost, pollution-free; Shortcoming is that ball milling degree is wayward, and insolubles content is higher, and reaction atmosphere is nitrogen, argon gas or vacuum environment, and cost is higher; The advantage of solid microwave method is that heating is rapid, and generated time is short.Shortcoming is that heating installation adopts microwave oven, and the method only limits to laboratory study, is not suitable for actual industrial production.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of preparation method of liquid di-oxalate lithium borate; can overcome the deficiency of the liquid di-oxalate lithium borate method of existing preparation; at lower cost, energy consumption, efficient synthesizing liquid di-oxalate lithium borate, meets the needs that industrial scale is produced.
For solving the problems of the technologies described above, the invention provides a kind of preparation method of liquid di-oxalate lithium borate, comprising:
Under 0～80 ℃ of dry environment, in organic solvent, add boron-containing compound and contain oxalate compound, stirring makes described boron-containing compound, contains oxalate compound dissolution in described organic solvent, in described organic solvent, add lithium-containing compound or lithium simple substance, the mol ratio that makes elemental lithium, boron and oxalate denominationby in described organic solvent is 1～2:1:2～3, stirs, after question response completes, filter, precipitation, products therefrom is liquid di-oxalate lithium borate.
Beneficial effect of the present invention is: by usining organic solvent both as reaction medium, as the solvent of finished product, raw material fully dissolves and reaction in medium, improves speed of reaction and finished product yield again, and product di-oxalate lithium borate is dissolved in finished product solvent.The method has been saved the recrystallization repeatedly prepared in solid di-oxalate lithium borate technique, filtration, the operation such as dry, has saved large content of starting materials, has reduced the discharge of waste.Than Solid Double Lithium bis (oxalate) borate, liquid di-oxalate lithium borate can directly be prepared electrolytic solution as one of raw material or raw material again, has saved dissolving, has filtered the operations such as insolubles, has improved working efficiency.Therefore, liquid di-oxalate lithium borate of the present invention, than solid-state, can reduce synthetic and preparation electrolytic solution operation, enhances productivity, and reduces energy consumption and cost, significant with use to the large-scale promotion of di-oxalate lithium borate.
