Description
Technical field
The present invention relates to field of material technology, particularly relate to a kind of solid-state sode cell and preparation method thereof.
Background technology
Lithium rechargeable battery has that specific energy density is big, operating temperature range width, discharge and recharge life-span length, self discharge are little,
The advantages such as memory-less effect is little, its mass energy density can reach 280Wh/kg it is considered to be the most promising electrochmical power source.Closely
All show, at electrokinetic cell and energy-storage battery field, the development prospect attracted people's attention over Nian.
But, tellurian lithium resource does not enrich, and elemental lithium abundance in the earth's crust is only 0.0065%, and is distributed
The most uneven, along with following electric automobile, the arrival in intelligent grid epoch, the price that lithium resource is short and expensive necessarily becomes
Restrict the key factor of its development.Accordingly, it would be desirable to the energy-storage battery system of Development of Novel.And the abundance that sodium is in the earth's crust reaches
2.64%, cheap, and sodium ion has similar embedding mechanism, sodium ion secondary battery weight the most in recent years with lithium ion
Newly paid close attention to by people.
On the other hand, the most traditional secondary cell many employings liquid organic electrolyte, leakage, electrode corrosion easily occur
Etc. problem, at an excessive temperature, in some instances it may even be possible to blast.Although using polymer dielectric can alleviate these to a certain extent
Problem, but can not fundamentally solve.And use inorganic solid electrolyte, it is possible not only to get rid of the leakage that brings of electrolyte and asks
, and there is not the resolution problem of liquid electrolyte in topic so that solid-state sode cell security performance higher (Nature, 2008,451
(7179): 652-657, Nature, 2001,414 (6861): 359-367), cycle life longer (J.Power Sources,

Sample (Adv.Energy Mater., 2011,1 (1): 10-33).Solid electrolyte also acts the effect of barrier film simultaneously, therefore
Simplify the structure of battery, it is not necessary under protective atmosphere, carry out the encapsulation of battery, reduce cost of manufacture.
Development solid-state sode cell, it is crucial that find the high solid electrolyte of ionic conductivity and reduce electrode material and
The great interface resistance that solid-solid contact between solid electrolyte is brought.Wherein the contact problems between solid-solid are from very great Cheng
The performance of solid-state sode cell is determined on degree.Can be by the method for ball milling or at active material surface coating electrolyte thin film
The contact area increased in combination electrode between electrode active material and electrolyte powder passes to the ion improving combination electrode
Lead performance, or reduce the interface resistance between electrode and solid electrolyte by the method for high-temperature heat treatment, thus promote
The performance of solid-state sode cell.
But above-mentioned treating method technique is the most complicated, and cost is high, it would be desirable to seek that a kind of preparation technology is simple, low cost
Honest and clean, formation efficiency is high, and be applicable to industrialization produce solution.
