Description
Technical field
The utility model relates to metal-air battery technical field, specifically a kind of metal-air electricity using phase-change temperature control
Pond.
Background technique
Metal-air battery is also metal fuel battery, is substantially metal（Mainly magnesium, aluminium, zinc）With the oxygen in air
Electrochemical reaction occurs for gas.Metal-air battery main component includes metal pole, air cathode, electrolyte and battery case etc..
The outstanding advantages of metal-air battery are that specific energy is big, shelf-stable；Relative deficiency is that the internal resistance of cell is larger, output specific power compared with
It is small.Because the internal resistance of cell is big, when discharge current is larger, battery spontaneous heating is obvious, and temperature is caused to increase, and on the one hand accelerates electrolysis
On the other hand the evaporation of liquid influences the service life of air cathode.
Existing smaller power metal-air battery, usually not consideration climate control issues；And the metal of relatively high power is empty
Gas battery pack generallys use air-cooled or water cooling method control temperature and increases, and this itself consumes the electricity of a large amount of preciousnesses again
Energy.Therefore, for the metal-air battery of relatively high power, how temperature is controlled, is an important issue.
Phase-change thermal storage technology is a kind of important technology for rationally and efficiently using the existing energy and improving efficiency of energy utilization, is
One more active research direction of world's energy-saving field in recent years.Phase-change thermal storage realizes energy using the latent heat of phase change of material
Storage and utilization, be alleviate energy supply and demand both sides unmatched effective means on time, intensity and place.Phase-change thermal storage skill
The core of art is phase-change material, can absorb in phase transition process or discharges big energy, is called latent heat of phase change.What phase transformation occurred
Temperature is referred to as transformation temperature or phase transformation critical-temperature, is denoted as Tm.In general, phase transformation critical-temperature Tm in 50~90 DEG C of models
Material in enclosing divides normal low temperature phase change heat accumulating into, and such material is very widely used in building and daily life.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of metal-air batteries using phase-change temperature control, utilize phase
The latent heat of phase change of change heat storage material carries out the temperature control of passive type, does not consume electric energy, and the temperature of metal-air battery is tieed up
It holds within the temperature range of normal battery operation.
The technical solution of the utility model is：
A kind of metal-air battery using phase-change temperature control, includes battery case, and air cathode is arranged in battery case
Side wall on, contacted on one side with outside air, the electrolyte contacts inside another side and battery case, metal pole and phase-change thermal storage
Material is plugged in battery case and impregnates in the electrolytic solution, metal pole be located at air cathode and phase-change heat-storage material it
Between, and be connected between metal pole and air cathode by electrolyte ion, metal pole and phase-change heat-storage material thermal contact conductance.
There are two metal pole and two air cathodes for setting in the battery case, and two air cathodes divide
Not Wei Yu two metal pole outside, the phase-change heat-storage material be set between two metal poles and respectively with two metals
Pole thermal contact conductance.
The phase-change heat-storage material connects between battery case and metal pole and respectively with battery case and metal pole
It touches thermally conductive.
The metal-air battery is magnesium air battery, aluminium-air cell or zinc-air battery.
It is 50-60 DEG C of phase-change material that the phase-change heat-storage material, which selects phase transition temperature,.
The phase-change material is the solid-liquid phase change material of solid-solid phase change material or encapsulating structure.
The solid-solid phase change material selects 2- amino-2-methyl -1,3- propylene glycol.
The solid-liquid phase change material selects paraffin 54, paraffin 56, paraffin 58 or paraffin 60.
The advantages of the utility model：
The phase-change heat-storage material of the utility model is arranged between metal pole and metal pole, or in metal pole and battery case
Between body, guarantee ion conducting that is good thermally conductive, but not influencing metal pole and air cathode.
The phase transition temperature Tm of phase-change heat-storage material is equal to or slightly above the optimum working temperature of metal-air battery.Such as
For magnesium air battery system, may be selected between 50 degrees Celsius to 60 degrees Celsius.At this temperature, that is, there is preferable electric discharge
Performance, but it is too fast not will lead to electrolyte evaporation.
Under normal conditions, battery initial temperature is less than phase transformation critical-temperature Tm's.In discharge process, due to metal-air
The internal resistance of cell is larger, and battery temperature has certain raising.If discharge current is larger and the duration is longer, temperature can always on
It rises, until phase transformation critical-temperature Tm, phase-change heat-storage material is undergone phase transition at this time, heat is absorbed, and battery temperature remains unchanged.Cause
It is very big for the latent heat of phase-change heat-storage material, so this temperature can keep longer period of time.If lasting heavy-current discharge,
Generating heat promotes phase-change heat-storage material to change completely, and entire battery temperature continues to improve once again.In this case, phase transformation
The effect of heat accumulating, which is to increase battery temperature, plays hysteresis, when substantially extending effective work of battery
Between.
Another situation, battery are the heavy-current discharges of intermittence.When high current works, fever is obvious, partial phase change
Heat accumulating is transformed into high-temperature-phase from low-temperature phase, but there is no undergoing phase transition completely, battery temperature is also maintained at critical-temperature Tm；
And when electric current becomes smaller or stops working, reverse transformation occurs for phase-change heat-storage material, and is returned to original state（Low-temperature phase）,
Prepare thermal shock caused by receiving heavy-current discharge next time.Obviously, phase-change heat-storage material puts the high current of intermittence
Electricity has good temperature control action.
