Abstract

A method for increasing volume of Li ionic cells characterizes in pre-reacting to deposit a solid electrolyte (SEI) layer, first of all, a said electrolyte film is formed on the negative material surface with reaction and deposition by electrochemical or chemical method. After assembling SEI film and various other materials into Li ionic cells, the formation of passive layer is reduced since contact of negative material and electrolyte is isolated which can reduce or completely eliminate irreversible volume of Li ionic cells.

Description

A kind of method that improves capacity of lithium ion battery
Technical field
This patent relates to storage battery, particularly lithium ion battery.
Background technology
Lithium ion is being subjected to extensive concern for over ten years as the green high-capacity power supply, and it has the energy height, cyclicity is good and the characteristics of low discharge.In order to give full play to the performance characteristics of lithium ion battery, worldwide the researcher carries out positive research to lithium ion battery.In lithium ion battery first charge-discharge process, electrode material and electrolyte react on liquid-solid phase boundary, form the passivation layer that one deck is covered in electrode material surface, passivation layer has the characteristic of solid electrolyte, therefore, this tunic is also referred to as the SEI film, i.e. Solid electrolyte interphase (solid electrolyte boundary).The SEI film is in nonaqueous solvents, and alkali metal and organic electrolyte react and the thin layer that covers the surface of formation.SEI film tool is insoluble, makes alkali metal passivation in organic solvent, and alkali metal cation can free in and out the SEI film, and solvent molecule but can't pass through the SEI layer, and also can produce corresponding solid-state version electrolyte interface in the process that lithium embeds material with carbon element.The formation of passivation layer produces significant effects to the performance of lithium ion battery, makes the first charge-discharge irreversible capacity increase, and has reduced the energy of lithium ion battery.
Technology contents
The application's purpose is to overcome deficiency of the prior art, by the battery irreversible capacity loss that improves to battery material, improves capacitance.
The application's scheme is reactive deposition one deck solid electrolyte layer (SEI) in advance on lithium ion battery negative material.After being assembled into battery with this material, completely cut off negative material and contact with electrolytical in use-charging cycle first, reduced the formation of passivation layer, passivation layer will no longer be grown on solid electrolyte film, eliminate the lithium ion battery irreversible capacity, thereby improved capacitance.
The reactive deposition solid electrolyte layer, available electrochemical method, the method for also available general chemistry reactive deposition, the electrolyte that electrolyte or reactive deposition liquid adopt is identical with the electrolyte of battery.
For example: in the vacuum electrochemical vessel of dry (relative humidity is less than 3%), put into and use LiPF 6(EC+DEC) electrolyte of electrolyte configuration is anodal with the graphite material, and the lithium sheet is a negative pole, the logical direct current of going up, and how many size of current decides on material, and in energising-discharge process, graphite material and lithium sheet surface reaction deposition form solid electrolyte film.The graphite material or the lithium sheet of above-mentioned reactive deposition solid electrolyte film are assembled into lithium ion battery as negative pole, become a kind of battery of high power capacity.
Electrolyte also can adopt LiClO 4Or LiAsF 6Or LiBF 4As solute, PC or DME or EC or DC or DMC prepare as solvent.
Above-mentioned solute adopts wherein a kind of; Above-mentioned solvent can adopt wherein a kind of, also can two or more mixed use.

Claims (2)

1. a method that improves capacity of lithium ion battery is characterized in that: pre-reaction deposition one deck solid electrolyte on cell negative electrode material.
2. the method for claim 1 is characterized in that: electrolyte employing LiClO 4Or LiPF 6Or LiAsF 6Or LiBF 4As solute, PC or DME or EC or DC or DMC or DEC prepare as solvent.
