Specific embodiment

Example embodiments are described in detail here, and the example is illustrated in the accompanying drawings.Following description is related to When attached drawing, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements.Following exemplary embodiment Described in embodiment do not represent all implementations consistent with this disclosure.On the contrary, they be only with it is such as appended The example of the consistent device and method of some aspects be described in detail in claims, the disclosure.

The battery of mobile phone mostly uses Soft Roll polymer Li-ion battery at present, namely encapsulated using aluminum-plastic composite membrane lithium from Sub- battery, when battery surface is scratched, will cause electrolyte leakage in battery and the case where corrosion cell surface, with electrolyte Leakage, damaged area can be expanded, so that the service life of battery is reduced, so that the reliability of battery is lower.

In order to promote the reliability of battery, generally will do it visual inspection or detect to occur the battery of leakage using instrument, but It is that some subtle scuffings of battery surface are discovered due to being not easy, is often missed out, after a period of time has passed, due to The breakage of the entrance of steam, battery can constantly expand, and cause battery bulging, electricity sharp-decay, once therefore battery surface go out Skin lesion is now scratched, if can not effectively inhibit the phenomenon that damaged sprawling, the mobile phone finally completed using the battery assembly, only The case where waiting mobile phone whole swelling cracking occur, cannot be started up could find that the problem of battery surface is scratched is deposited when occurring In.

In order to promote the reliability of battery, the disclosure provides a kind of battery, and Fig. 1 is shown according to an exemplary embodiment The structural schematic diagram of battery, as shown in Figure 1, the battery includes: battery body 11, battery body encapsulated layer 12 and has swelling solidifying The battery leakage of glue effect detects plugged zone 13.

Wherein, battery body encapsulated layer 12 is arranged in the outside of battery body 11；The outside of battery body encapsulated layer 12 is arranged Battery leakage detects plugged zone 13.

(such as: in the transportational process of battery) can not only occur before not being assembled into terminal device for the breakage of battery； Battery breakage also occurs that be assembled into terminal device after；That is, terminal device falls repeatedly in assembling, transport and routine use During will cause the breakage of battery.

Exemplary, above-mentioned battery body 11 may include: electrolyte and battery core.

And above-mentioned battery leakage detection plugged zone 13 is made with after the electrolyte contacts in steam or battery due to being swollen With, the volume in battery leakage detection plugged zone 13 with the part of the electrolyte contacts in steam or battery can expand several times, Swell gel reaction can occur.

So, before battery is not assembled into terminal device, since visual inspection and instrument detection can not discover concealed location Breakage or the small breakage of battery surface, at this time when battery occurs damaged, battery leakage detect in plugged zone 13 with steam Or the volume of the part of the electrolyte contacts in battery can expand several times, so that damage location will clearly, to be easy to Damaged investigation is carried out to battery appearance, the probability of leakage battery outflow is reduced, improves the reliability that battery uses, to be promoted most The reliability that the terminal device being assembled into eventually uses.

And battery breakage occur using battery assembly at terminal device after, when battery is damaged, overflow at damaged mouth Electrolyte out, electrolyte are contacted with battery leakage detection plugged zone 13, since battery leakage detects the swelling action of plugged zone 13, Volume expansion, then since gel reaction can block rapidly damaged mouth, obstruct damaged mouth in time and contacted with the external world, prevent electrolyte It further overflows and is largely contacted in steam, inhibit the sprawling of leakage corrosion, extend the service life of battery, improve battery use Reliability.

Due to being to be made using battery leakage detection plugged zone 13 with the swelling after the electrolyte contacts in steam or battery It is whether damaged and damaged portion is blocked for detecting battery, it is therefore desirable to be packaged battery body 11, to keep away Exempt from the electrolyte contacts in battery leakage detection plugged zone 13 and battery body 11.

It is worth noting that, above-mentioned electrolyte is that a kind of citing in practical applications can be according to battery body type Difference, detect plugged zone 13 using the battery leakage of different materials, and above-mentioned battery leakage detection plugged zone 13 can be with With the substance revealed in the battery body carry out it is above-mentioned react, such as: may include organic solvent in battery body 11, And battery leakage detection plugged zone 13 at this time can carry out above-mentioned react with the organic solvent revealed in the battery body.

The technical scheme provided by this disclosed embodiment can include the following benefits: electricity is arranged in the outside of battery body Pond ontology encapsulated layer；There is the battery leakage of swell gel effect to detect plugged zone for the outside setting of battery body encapsulated layer.By The position of battery breakage can be effectively detected by swelling reaction in battery leakage detection plugged zone, and in battery breakage After damaged mouth can be blocked by gel reaction, to effectively improve the reliability of battery, extend battery uses the longevity Life.

In one embodiment, as shown in Fig. 2, above-mentioned battery further include: wearing layer 14；The setting of wearing layer 14 is leaked in battery The outside of liquid detection plugged zone 13.

The function of battery leakage detection plugged zone 13 is caused in order to avoid the abrasion to battery leakage detection plugged zone 13 It reduces, therefore, one layer of wearing layer 14 is also set up in the outside of battery leakage detection plugged zone 13, thus effective protection battery leakage Liquid detection plugged zone 13 is not worn.

Wherein, battery leakage detection plugged zone is made of organic gel materials.Such as: organic gel materials are wafer.

Wearing layer is made of resin material or nylon material；And resin material may include: polypropylene.
