Abstract
The invention discloses a kind of preparation method of pre- embedding lithium cathode sheet, include the following steps：(1), active material admixture containing lithium salt is attached on porous collector by Physical and forms active material layer, obtain the negative plate through the pre- embedding lithium of physics；(2), the negative plate through the pre- embedding lithium of physics obtained by step (1) is inserted into progress constant current charge-discharge processing in organic electrolyte containing lithium salt, obtains the negative plate through the pre- embedding lithium of electrochemistry.The present invention is combined by the pre- embedding lithium of the pre- embedding lithium of physics and electrochemistry, makes up the microcosmic embedding lithium inhomogeneities by the pre- embedding lithium of physics, it is long to solve the problems, such as that the pre- embedding lithium of electrochemistry depth takes.
Description
Technical field
Preparation method and the negative plate that is obtained by this method the present invention relates to a kind of pre- embedding lithium cathode sheet, belong to storage
Can devices field.

Can the energy storage device of industrialized production mainly include lithium ion battery (LIB) and double layer capacitor (EDLC, that is, surpass
Level capacitor), achieve and be widely applied.Lithium ion battery has the advantages that energy density is high, and there is service life is short, work(
The low density shortcoming of rate, ultracapacitor have the advantages that output power, have extended cycle life, and ask there are energy density is low
Topic.
Lithium-ion capacitor (LIC) uses lithium ion battery and double layer capacitor mixed structure, and cathode uses activated carbon,
Anode is using materials such as graphite.Have the height output, long-life characteristics and lithium ion battery high-energy-density of double layer capacitor concurrently
Characteristic.
Whether lithium ion battery or lithium-ion capacitor, are directed to the pre- embedding lithium of anode.And pre- embedding lithium is equally two
The core technology of person.All there is irreversible embedding lithium in varying degrees during first charge-discharge in most of embedding lithium electrodes.Together
When, in lithium-ion capacitor the behavior also result in the anion with same molar in the irreversible suction in positive-active surface
It is attached.Body ion concentration decrease to some degree in electrolyte can be caused, and further results in the reduction of capacitance, most
The charge-discharge characteristic of lithium-ion capacitor can be seriously affected eventually.Therefore, a degree of pre- embedding lithium is carried out to anode, on the one hand may be used
To solve the above problems, on the other hand anode current potential can be made significantly to decline, so as to improve energy density and service life cycle.
The pre-embedding lithium method illustrated in patent CN101138058B, is using lithium metal as lithium source, uses the gold with through hole
Category paper tinsel is collector, and lithium metal is placed in anode relative position, utilizes the electrical potential difference between them to discharge by short circuit manner, from
And realize pre- embedding lithium.But cause preparation process will, it is necessary to strictly control the content of water and oxygen due to the active very high of lithium
Ask harsh；Multicellular metal foil is used at the same time, adds manufacture cost；In addition, short circuit manner is not easily-controllable, the inequality of embedding lithium can be caused
Even property.

It is slowly dissolve into electrolyte and forms lithium ion, so as to is embedded into anode.This method uses lithium piece, adds operating environment
It is required that and lithium piece there is certain danger in itself, and pretreatment time is long.By positive and negative anodes in patent CN104681311A
It is connected on charge-discharge test instrument, once to be discharged after once charging for a circulation, 100 times repeatedly, reaches pre- embedding lithium
Method, this two kinds time-consuming, and the uniformity of embedding lithium is not good enough.
The pre- embedding lithium of electrochemistry can be very good to realize the uniform pre- embedding lithium of both macro and micro aspect, but shortcoming is to take long,
One layer of SEI film is inevitably produced on anode using the pre- embedding lithium of electrochemistry, this not only slow down the insertion of lithium with it is embedding go out
Speed, and increase the internal resistance of storing up electricity device.Shi Zhiqiang seminars (J.Zhang, H.Wu, J.Wang, J.Shi, Z.Shi,
