Description
Technical field
The present invention relates to a kind of protective layer for serondary lithium battery negative pole.Belong to electrochemical field.
Background technology
With the development of science and technology people adapt to the miniaturization of various batteries, lightweight in the urgent need to a kind of high energy density cells
Trend, at this moment, lithium ion battery is difficult to meet needs.Due to the limitation of the theoretical specific energy of graphite, lithium ion battery is difficult
As high energy density cells.Battery in theory with lithium metal as negative pole can turn into the battery of higher energy density.Metal
The specific capacity of lithium is up to 3860mAh/g, and the exchange current density of lithium electrode is big, polarizes small, is ideal electrode material
Material.But because metal lithium electrode will produce Li dendrite in charge and discharge process.When Li dendrite comes off from pole plate, battery can be caused to hold
The loss of amount, if Li dendrite is gradually given birth to, may pierce through barrier film and cause internal short-circuit of battery, trigger battery catches fire or blast.
This problem ultimately results in lithium secondary battery and commercially not yet succeeds.
For protection cathode of lithium, it is also proposed that kinds of schemes perhaps in document, including being applied with protective layers such as polymer, ceramics or glass
Overlay on cathode of lithium.United States Patent (USP) USP5460905, USP5462566 describes a kind of method, in the battery cathode of lithium and electricity
Mix a conjugated polymer film between solution matter, and USP5648187 and USP 5961672 describe cathode of lithium in the battery and
One layer of polymer film of conduction and preparation method thereof is pressed from both sides between electrolyte;United States Patent (USP) USP5314765 is also described on cathode of lithium
One layer of ceramic coating of covering.Also certain methods, United States Patent (USP) USP5387479, USP5487959, CN1297588A,
It is described in CN1726608A, CN1894821A, CN1938895A, CN101313426A etc..
Although proposing the various methods that protective layer is formed on cathode of lithium, the Li dendrite of cathode of lithium is not solved still at present
Problem.Still need to propose safety problem and cycle life of the more efficiently solution to solve the problems, such as cathode of lithium, so that
The high-energy-density of lithium secondary battery is achieved.
The content of the invention
