Description
Technical field
The present invention relates to secondary cell, more particularly to a kind of high-temperature Ni/H 2 battery.
Background technology
Since being studied and be successfully prepared since 1984, Ni-MH battery is because its excellent charge-discharge performance, nothing
The characteristics such as environmental pollution, are more and more widely applied in daily life.It is increasingly extensive with the purposes of Ni-MH battery, it is more next
More consuming device requirements are used at a higher temperature, such as emergency light, electric tool.Anode of nickel-metal hydride battery active material
For nickel hydroxide, negative electrode active material is hydrogen storing alloy powder.Battery can produce gas in charge and discharge process, but be due to battery
It is hermetic type structure, it is necessary to which inside battery air pressure is maintained near normal pressure, therefore it is required that GND can quickly absorb, release hydrogen
Gas, the charge efficiency of existing high-temperature Ni/H 2 battery is poor.
The content of the invention
In order to make up above-mentioned the deficiencies in the prior art, the present invention proposes a kind of high-temperature Ni/H 2 battery, can accelerated in battery
The circulation of gas, so that negative pole quickly absorbs gas, improves the charge efficiency of battery.
The technical problem of the present invention is solved by following technical scheme：
A kind of high-temperature Ni/H 2 battery, including shell, the battery core that is arranged in the shell and electrolyte；The battery core includes
Some first holes are distributed with positive plate, barrier film and the negative plate for overlaping and winding successively, the positive plate, it is described
It is distributed with barrier film and corresponds to covering one completely with the second hole of the first pore quantity identical, each described first hole
Individual second hole, the area of each first hole is more than the area of second hole of its correspondence covering.
Preferably, the area of each first hole is bigger by 20% than the area of second hole of its correspondence covering
~100%.
The area of first hole is bigger by 20%~100% than the area of the second hole of its correspondence covering, can neither influence
Short circuit does not occur for battery capacity, can guarantee that then the gas that positive pole is produced faster can be absorbed by barrier film by negative pole again.
Preferably, the shape and/or area all same of each first hole.
Preferably, the shape and/or area all same of each second hole.
Preferably, first hole is uniformly distributed on the positive plate in matrix；Second hole it is described every
It is uniformly distributed on film in matrix.
Preferably, second hole and the first hole are circle, the diameter of second hole on the barrier film
For 0.1mm-2mm.
The beneficial effect that the present invention is compared with the prior art is：The structure that the present invention passes through improvement positive plate and barrier film simultaneously
To improve the high-temperature behavior of Ni-MH battery, due to being respectively equipped with corresponding first hole and the second hole on positive plate and barrier film
, so there is passage in hole, the gas that positive pole is produced quickly then is born by barrier film between the both positive and negative polarity of battery
Pole is absorbed, simultaneously because the second hole area on barrier film is less than the area of the first hole on positive plate, such barrier film is remained to
Play a part of separating both positive and negative polarity without causing battery short circuit.
Brief description of the drawings
Fig. 1 is the positive plate and the schematic diagram of barrier film of the high-temperature Ni/H 2 battery in the preferred embodiments of the present invention.
Fig. 2 is that high-temperature Ni/H 2 battery and existing high-temperature Ni/H 2 battery in the preferred embodiments of the present invention exist respectively
The inner pressure curve contrast schematic diagram that 0.5C was filled after 180 minutes.
Embodiment
Below against accompanying drawing and with reference to preferred embodiment the invention will be further described.
The present invention provides a kind of high-temperature Ni/H 2 battery, in some embodiments including shell, be arranged on it is described outer
Battery core and electrolyte in shell；The battery core includes positive plate, barrier film and the negative plate for overlaping and winding successively, described
Be distributed with positive plate on some first holes, the barrier film be distributed with the second hole of the first pore quantity identical,
Each described first hole corresponds to one second hole of covering completely, and the area of each first hole is more than it
The area of second hole of correspondence covering.
In an embodiment of the present invention, the use environment temperature of battery can be referred to as high temperature ni-mh electricity higher than 45 DEG C
Pond.
In a preferred embodiment, high-temperature Ni/H 2 battery includes shell, the battery core being arranged in the shell and electrolysis
Liquid；Battery core includes positive plate, barrier film and the negative plate for overlaping and winding successively, as shown in figure 1, being distributed on positive plate 1
Have and be distributed with some first holes 11, barrier film 2 and the second hole of quantity identical 21 of the first hole 11, each first hole
11 correspondences completely cover second hole 21, and the area of each the first hole 11 is more than the second hole 21 of its correspondence covering
Area.In this example, the big circle such as some second holes 21 are simultaneously is uniformly distributed on barrier film 2 in matrix, and several the
One hole 11 is also to wait big circle and be uniformly distributed on positive plate 1 in matrix, a diameter of 1mm of the second hole 21, first
A diameter of 2mm of hole 11.
By the high-temperature Ni/H 2 battery AA1600mAh in above example and high-temperature Ni/H 2 battery of the prior art
AA1600mAh is filled 180 minutes under 0.5C respectively, and the internal pressure of battery is contrasted as shown in Fig. 2 in figure, curve A represents the present embodiment
High-temperature Ni/H 2 battery, curve B represents high-temperature Ni/H 2 battery conventional in the prior art, it follows that when battery is overcharged,
The high-temperature Ni/H 2 battery of the present embodiment, can more timely sponge gas of the positive pole due to overcharging generation than conventional scheme, electricity
