Description
Technical field
The present invention relates to technical field of lithium batteries, particularly belong to a kind of jetting machine lithium battery electrolytes.
Background technique
Lithium battery is usually made of anode, cathode and electrolyte.Wherein, anode includes cobalt acid lithium and many adding ingredients,
These substances generate the chemical reaction of charge and discharge by being coated on aluminium foil；Cathode is the nanoscales carbon dust such as graphite, these substances
It is used by being coated in the enterprising enforcement of copper foil.Electrolyte in electrolyte usually has lithium perchlorate, lithium hexafluoro phosphate etc., but with high chlorine
Sour lithium is that battery cryogenic effect made of raw material is bad, there is the danger of explosion, and Japan and the U.S. have been forbidden to use at present；And with containing
Battery performance made of fluorine lithium salts is good, no explosion danger, strong applicability, especially the battery made of lithium hexafluoro phosphate, except upper
It states outside advantage, future, the processing work of waste battery was relatively easy, to eco-friendly, in practical applications, hexafluorophosphoric acid
Although lithium has low temperature, high-temperature comprehensive property good, the without explosion advantage of safety, there is also hygroscopic hydrolysis generations simultaneously for it
Has the characteristics that the hydrofluoric acid of high corrosiveness.Aluminium foil and copper foil in the too fast corrosion positive and negative anodes of hydrofluoric acid in order to prevent, people
Make aluminium foil and copper often through the mode for increasing film for additive (such as polycarbonate and diethyl carbonate) in the electrolytic solution
The surface of foil forms one layer of excellent SEI film (solid electrolyte film).SEI film has organic solvent not capacitive, allow lithium from
Son freely passes in and out electrode and solvent molecule can not pass through, so that solvent molecule be prevented to insert the destruction to electrode altogether, improves battery
Cycle efficieny and the performances such as reversible capacity.Hydrofluoric acid present in electrolyte can destroy SEI film, thus effect of depth positive and negative anodes
The normal operation of function, and reduce the service life of lithium battery.Therefore, need to develop that a kind of corrosivity is small, can reduce hydrofluoric acid
On the novel electrolyte that positive and negative anodes influence, the service life of Lai Tigao lithium battery.
Summary of the invention
The object of the present invention is to provide a kind of jetting machine lithium battery electrolytes, to solve hydrogen present in liquid
Fluoric acid can destroy SEI film, thus the normal operation of effect of depth positive and negative anodes function, and service life for reducing lithium battery etc. lacks
It falls into.
To solve the above problems, the technical solution used in the present invention is as follows:
A kind of jetting machine lithium battery electrolytes, are made from the following raw materials in parts by weight: 12-24 parts of vinyl phosphate,
16-24 parts of phosphoric acid acrylic ester, 8-12 parts of 1,3-dioxolane, 4-10 parts of glycol dimethyl ether, 10-15 parts of vinylene carbonate,
20-40 parts of liquid lithium hexafluorophosphate, 4-8 parts of borosilicate glass powder, 2-4 parts of fire retardant, to diphosphonic acid benzene-like compounds 4-16
Part.
Further, it is made from the following raw materials in parts by weight: 20 parts of vinyl phosphate, 18 parts of phosphoric acid acrylic ester, 1,3- bis-
9 parts of butyl oxide link, 8 parts of glycol dimethyl ether, 12 parts of vinylene carbonate, 26 parts of liquid lithium hexafluorophosphate, borosilicate glass powder
6 parts, 3 parts of fire retardant, to 8 parts of diphosphonic acid benzene-like compounds.
Further, the fire retardant is three phosphonitrile of hexakis-methoxy basic ring, di(2-ethylhexyl)phosphate benzene toluene ester, one in 1- alkynyl phosphonate
Kind is several.
Compared with prior art, implementation result of the invention is as follows by the present invention:
A kind of jetting machine lithium battery electrolytes of the present invention add to diphosphonic acid benzene-like compounds, can accelerate SEI
The formation speed of film simultaneously keeps SEI film finer and close, repairs the breakage of SEI film, reduces the transmission range of lithium ion, improve lithium ion
Migration rate to reduce internal resistance, while can also inhibit the decomposition of organic solvent, substantially reduce gas production, guarantee lithium battery
Hydrofluoric acid can be effectively absorbed with excellent security performance and high temperature cyclic performance, while using borosilicate glass powder,
To weaken hydrofluoric acid to the corrosive effect of positive and negative anodes, extends the service life of product, prevent electrolyte on fire using fire retardant
Burning, lithium battery electrolytes component provided by the invention is simple and practical, and social benefit is obviously suitble to promote.
