Description
Technical field
The invention belongs to electrochemical energy storage cell fields, and in particular to a kind of high-temperature fusant cell apparatus and its preparation work
Skill.
Background technique
Currently, China is just entering the critical period of energy system in-depth reform, the development war of building global energy internet
It is slightly increasingly clear.Future global energy internet by be smart grid, extra-high voltage grid, clean energy resource extensive fusion, this need
Want more new energy storage devices, direction of energy control, distributed power grid and micro-capacitance sensor will realize commonly used, and energy storage skill
Art will coordinate these one rings of application.Currently, common power grid grade energy storage technology includes water-storage, compressed air storage
Energy, super capacitor energy-storage, superconducting energy storage, flywheel energy storage and all kinds of battery energy storages.Wherein, battery energy storage is converted with its energy and is imitated
The advantages that rate is high, system scale configuration is not limited by geographical environment flexibly, or not advantage of lower cost becomes distributed power grid and micro- electricity
Net preferred energy storage mode.However, in all kinds of battery energy storage technologies for having been carried out application, lead carbon battery service life it is short and
Environmental pollution is larger；Sodium-sulphur battery can be because of β-Al2O3Electrolyte membrance ruptures and leads to serious safety accident；Flow battery exists
Need to be broken through in terms of the critical materials such as amberplex；The production cost of lithium ion battery is still higher, and performance also need to be into one
Step improves.The above problem limits the development of power grid energy storage technology, is that it is hindered to realize one of commercialized principal element.
Under the background that energy-storage battery technology is urgently broken through, the D.R.Sadoway of Massachusetts Institute Technology in 2007
Professor proposes " liquid metal cell " new concept that can be used for power grid grade scale energy storage.This battery usually in hot operation,
Its positive and negative electrode is liquid metal, and electrolyte is inorganic, fluid or semi liquid state fused salt.The mutual not phase of anode, electrolyte, negative electrode material
It is molten, and because density variation is divided into three layers from the bottom to top.When work, battery forms positive grid alloy by negative metal and cathode metal
And it discharges；It correspondingly, is that negative metal and cathode metal charge by the electrolysis again of positive grid alloy.With traditional energy-storage battery
Compare, liquid metal cell have many advantages, such as lower cost for material, manufacturing process it is simple, can high power charging-discharging, stored up in power grid
The application prospect in energy field is very wide.
The outstanding problem that liquid metal cell faces at present is a lack of the effective insulated enclosure method for hot environment
And corrosion-resistant measure (Kim H, Boysen D A, Newhouse J M, et al.Liquid Metal Batteries-Past,
Present,and Future[J].Chemical Reviews,2013,113:2075-2099)。
Firstly, the negative electrode material and electrolyte chemical property of liquid metal cell are very active, 300 DEG C~700
DEG C operating temperature under battery material once with the contacts such as water, oxygen, nitrogen in air can in a short time deterioration failure to make
At degradation of cell performance.The general insulated enclosure method of liquid metal cell is that the insulated enclosure point of battery is drawn heating at present
Area, by conventional hermetic material (such as silicon rubber, epoxy resin) realization battery cathode bar and just under conditions of close to room temperature
Insulation and sealing between pole housing.Do so the volume, material cost and cost of manufacture on the one hand increasing battery.Another party
Face, due to that insulated enclosure point must be stretched out heating zone, room temperature sealing structure only allows the battery cloth of single layer in battery group
Office, cannot thus efficiently use height space, significantly increase the occupied area of battery pack.Meanwhile epoxy resin etc. seals
Glue usually requires longer curing time, and which increase the fabrication cycles of battery, is unfavorable for large-scale production.
Secondly, the battery material of inside battery exists when liquid metal cell is run at a high temperature of 300 DEG C~700 DEG C
There is strong corrosiveness to the battery component being in direct contact with it under molten condition, in battery During Process of Long-term Operation, this
Kind corrosiveness will lead to the lasting consumption of battery material (especially positive and negative electrode metal material) and cause subtracting for battery capacity
It is small.Meanwhile corrosion product constantly accumulates the variation that will also result in battery chemistries ingredient and internal microstructure in inside battery, into
And cause battery performance gradually degrade even battery failure.Existing liquid metal cell corrosion-resistant is set without special substantially
Meter.Although some liquid metal cells have installed the ceramics pipe outer for preventing positive and negative electrode short circuit additional inside its Stainless Steel Shell, keep away
Exempt from battery material directly to contact with battery inner wall, delays the corrosion to battery inner wall to a certain extent, but due to insulation
The thermal expansion coefficient of ceramic tube is usually less than Stainless Steel Shell, will appear obvious gap between the two under battery operating temperature,
At this moment the electrode and electrolyte of liquid are easy to occur to leak and cause to corrode to battery inner wall.
Summary of the invention
