Description

A kind of power lithium-ion battery
Technical field
This utility model relates to a kind of power lithium-ion battery.
Background technology
At the dynamic lithium battery used, there is service life cycle at present short, poor radiation, battery temperature mistake easily occurs High danger;And not there is overcharging resisting function, and the defect of poor stability, and the housing of metal material, easy rust corrosion;A lot Time raise suddenly due to battery temperature, and be not easy to be found, cause burning the most serious problem.In consideration of it, propose The technology contents that this use is novel.
Utility model content
The purpose of this utility model there are provided a kind of power lithium-ion battery.This utility model has heat dispersion Good, security performance is good, service life length feature.
For reaching above-mentioned purpose, the technical solution of the utility model is:
A kind of power lithium-ion battery, including T-shaped metal shell, described both sides, T-shaped metal shell top highlight Spot size is identical;Below protruding parts, battery core body is installed in described T-shaped metal shell;Described T-shaped metal In housing, protruding parts is provided with spacer ring;Described T-shaped metal shell top seal weld is connected to metal cover board;Described metal Positive pole hole and negative pole hole is offered on cover plate;Described battery core body is connected with anode pole piece, cathode pole piece respectively, and described Anode pole piece, cathode pole piece are positioned at outside metal cover board after passing positive pole hole, negative pole hole the most respectively after passing spacer ring, and described is positioned at It is parallel with Zener diode between anode pole piece and cathode pole piece outside metal cover board;It is welded with metal on described metal cover board Link, described metallic connexion frame is provided with 2 for the fixed claw connecting temperature acquisition line;Described T-shaped metal Housing and metal cover board internal face are coated with insulating protective layer;Remove on described T-shaped metal shell and metal cover board outside wall surface It is also coated with insulating protective layer outside the region of welded and installed metallic connexion frame.
Described T-shaped metal shell is T-shaped aluminum enclosure or T-shaped Stainless Steel Shell;Described metal cover board is aluminum Cover plate or rustless steel cover plate.
The beneficial effects of the utility model are: a kind of power lithium-ion battery of the present utility model, perfect heat-dissipating, safety Performance is good, and service life is long;Especially when it being charged or keeping in repair replacing, remove and install conveniently, it is easy to carry out safeguarding and Change, and simple in construction is firm, the setting of Zener diode, can overcharging resisting charging, it is to avoid battery is caused by big voltage Damage;Secondly battery stability and accuracy to temperature data acquisition in test process is ensured, can be to test process, work Process or the too high problem of charging process battery surface temperature monitor early and carry out judgement process in time;Also help reduction electricity The risk of pond internal corrosion.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Embodiment 1
As it is shown in figure 1, a kind of power lithium-ion battery of the present embodiment, including T-shaped metal shell 1, described is T-shaped Metal shell 1 is aluminum enclosure or Stainless Steel Shell;Described both sides, T-shaped metal shell 1 top protruding parts is equivalently-sized;Institute Below protruding parts, battery core body 2 is installed in the T-shaped metal shell 1 stated;Protuberance in described T-shaped metal shell 1 Position is provided with spacer ring 8;Described T-shaped metal shell 1 top seal weld is connected to metal cover board 9, and described metal cover board 9 is aluminum Cover plate or rustless steel cover plate;Positive pole hole 3 and negative pole hole 4 is offered on described metal cover board 9;Described battery core body 2 is respectively Be connected with anode pole piece 5, cathode pole piece 6, and described anode pole piece 5 pass spacer ring 8 after pass positive pole hole 3 again after be positioned at metal Outside cover plate 9, described cathode pole piece 6 is positioned at outside metal cover board 9 after passing negative pole hole 4 again after passing spacer ring 8, and described is positioned at gold Belong to and be parallel with Zener diode 7 between anode pole piece 5 and cathode pole piece 6 outside cover plate 9, when charging voltage is more than Zener diode Breakdown reverse voltage time, be equivalent between lithium ion battery positive and negative electrode directly connect, can overcharging resisting charging, such that it is able to have Effect avoids the damage that battery is caused by big voltage, increases the service life, and improves safety;Weld on described metal cover board 9 Have metallic connexion frame 11, described metallic connexion frame 11 is provided with 2 for the fixed claw 10 connecting temperature acquisition line, by electricity Pond temperature acquisition line penetrates fixed claw 10, tests battery surface temperature, it is ensured that temperature data is adopted in test process by battery The stability of collection and accuracy, can to the too high problem of test process, work process or charging process battery surface temperature early Monitor and carry out judgement process in time;Described T-shaped metal shell 1 and metal cover board 9 internal face are coated with insulating protective layer; It is also coated with in addition to the region of welded and installed metallic connexion frame 11 on described T-shaped metal shell 1 and metal cover board 9 outside wall surface Insulating protective layer, advantageously reduces the risk of internal cell corrosion.
A kind of power lithium-ion battery of the present embodiment, perfect heat-dissipating, security performance is good, and service life is long;Exist especially When it being charged or keeps in repair replacing, remove and install conveniently, it is easy to safeguard and change, and simple in construction is firm, voltage stabilizing The setting of diode, can overcharging resisting charging, it is to avoid the damage that battery is caused by big voltage;Secondly ensure that battery was being tested Stability and accuracy to temperature data acquisition in journey, can be to test process, work process or charging process battery surface temperature Spend high problem monitor early and carry out judgement process in time;Also help the risk reducing internal cell corrosion.
