Abstract

The utility model discloses a lithium-air fuel hybrid battery which comprises a shell and a lithium-air battery, and is characterized in that a fuel cell is arranged on the shell; the positive electrode of the fuel cell, the positive electrode of the lithium-air battery and the shell form an air cavity; the positive electrode of the lithium-air battery and the positive electrode of the fuel cell are connected in parallel to form the positive electrode of the hybrid battery; and the negative electrode of the lithium-air battery and the negative electrode of the fuel cell are connected in parallel to form the negative electrode of the hybrid battery. Because the lithium-air battery and the fuel cell are combined through a shared air cavity in a lithium-air alcohol hybrid battery, the battery has high specific energy and high power; the air cavity provides air for the positive electrode of the fuel cell and the positive electrode of the lithium-air battery, and the space is saved; and moreover, the lithium-air fuel hybrid battery provides a guarantee for the discharge requirements of different electric appliances.

Description

The empty fuel mix battery of lithium
Technical field
The utility model relates to the empty fuel mix battery of a kind of lithium.
Background technology
The empty battery of lithium is that a kind of lithium metal that utilizes is as negative pole, with the novel battery of airborne oxygen as positive pole.Its operation principle is: the lithium metal of negative pole becomes lithium ion after discharging electronics, and lithium ion passes electrolyte and combines to generate lithia anodal with oxygen and from the electronics that external circuit flows into.The energy density of the empty battery of lithium is high, and the specific energy of the empty battery of lithium is 5210Wh/kg (comprising oxygen quality) or 11140Wh/kg (not comprising oxygen quality) in theory.But because the discharging current of the empty battery of lithium is less than normal, its power characteristic is low.
Summary of the invention
The technical problem that the utility model will solve provides the empty fuel mix battery of lithium that a kind of energy density is big, power characteristic is good.
The technical solution of the utility model is:
The empty fuel mix battery of a kind of lithium; Comprise housing, the empty battery of lithium; Its special character is: on housing, also be provided with fuel cell; The positive pole and the housing of the positive pole of said fuel cell, the empty battery of lithium surround an air chamber, and it is anodal that the anodal parallel connection of the positive pole of the empty battery of said lithium, fuel cell forms hybrid battery, and the negative pole parallel connection of the negative pole of the empty battery of said lithium, fuel cell forms the hybrid battery negative pole.
Said fuel cell is an alcohol fuel battery, with the average specific energy of further raising hybrid battery.
The beneficial effect of the utility model is:
1, in the empty battery discharge procedure of lithium; Has higher specific energy; And in the fuel cell electric discharge process, having higher power characteristic, the empty pure hybrid battery of lithium organically combines two kinds of batteries through shared air chamber; The specific energy of the empty fuel mix battery of lithium is between empty battery of lithium and fuel cell, much larger than common lithium battery.
Empty battery of lithium and fuel cell provide electric current jointly when 2, supplying power, the electric current of the voltage * battery of the power=battery of battery, because electric current increases, the power of battery increases greatly.
The 3 anodal all consume oxygen owing to fuel cell and the empty battery of lithium, the positive pole and the housing of the positive pole of fuel cell, the empty battery of lithium surround an air chamber, for the positive pole of fuel cell, the positive pole of lithium sky battery provide air, have practiced thrift the space.
4, the empty pure hybrid battery of this lithium is simple in structure, has higher specific energy and power characteristic, for the discharge demand of different electrical appliances provides safeguard.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the right view of Fig. 1.
Among the figure: housing 1, the empty battery 2 of lithium, lithium sheet 201, barrier film 202, organic electrolyte 203, air electrode I 204, air chamber 3, alcohol fuel battery 4; Air electrode II 401, solid electrolyte 402, pure electrode 403; Fuel cavity 404, hybrid battery positive pole 5, hybrid battery negative pole 6.
Embodiment
As shown in the figure, the empty fuel mix battery of this lithium comprises housing 1, is arranged on the empty battery 2 of lithium on the housing 1, on housing 1, also is provided with fuel cell.The empty battery 2 of described lithium comprises as anodal air electrode I 204, organic electrolyte 203, as the lithium sheet 201 of negative pole, between lithium sheet 201 and the organic electrolyte 203, be provided with barrier film 202 between organic electrolyte 203 and the air electrode I 204.Said fuel cell is an alcohol fuel battery 4, also can adopt hydrogen fuel cell, phosphoric acid fuel cell, and alcohol fuel battery 4 is by as the air electrode II 401 of positive pole, solid electrolyte 402, constitute as the pure electrode 403 and the fuel cavity 404 of negative pole.The positive pole and the housing 1 of the positive pole of said alcohol fuel battery 4, the empty battery 2 of lithium surround an air chamber; The anodal parallel connection of the positive pole of the empty battery 2 of said lithium, alcohol fuel battery 4 forms hybrid battery positive pole 5, and the negative pole parallel connection of the negative pole of the empty battery 2 of said lithium, alcohol fuel battery 7 forms hybrid battery negative pole 6.
