Dew, battery failure, serious conditions also occur that short circuit produces naked light and causes safety problem, so needing to research and develop a kind of lithium-ion electric
Pond, the stress from outside can be resisted, there is provided hard packaging shell, and can when inside battery produces slight pressure difference
Neutralizing in time, and can maintain the balance of internal pressure, avoid further deteriorating, increase the stability of inside battery.
Utility model content
The utility model embodiment provides a kind of hard shell lithium ion battery that can stablize internal pressure, when in battery
When small pressure change occurs for portion, the balance of internal pressure can be maintained, increases the stability of inside battery.
To solve the above problems, the technical scheme that the utility model embodiment uses is as follows：
A kind of hard shell lithium ion battery that can stablize internal pressure, it includes battery plus-negative plate, battery core, electrolysis
Liquid, external package casing, the battery plus-negative plate are connected in battery core and stretched out from external package casing, and the battery core is placed in outsourcing
Fill in the electrolyte in housing, these constitute the fundamental of lithium battery, wherein the external package casing can not using hard
Plastic deformation material is made, and very high external intensity can be brought to battery, improves stress anti-pressure ability, the external package casing
Immersed with the closed rubber storage chamber for being marked with gas in interior i.e. electrolyte, the closed rubber storage chamber is comprehensive closed storage chamber, its
Internal gas completely cuts off with electrolyte completely, and various reactions of the closed rubber storage chamber not on inside battery produce any influence, should
The effect of closed rubber storage chamber is that unstable reaction occurs when lithium battery interior discharge and recharge, internal pressure increase or diminution, this
When due to closed rubber storage chamber memory storage be gas, it is easy to influenceed to change volume size by inside battery pressure, allow battery
Internal pressure is stable within the specific limits, improves battery security.
Further, the initial value that the gas atmosphere in the closed rubber storage chamber is set in battery production is 0.8
Standard atmospheric pressure, also imply that inside battery air pressure is again set at 0.8 standard atmospheric pressure in production, now in battery
Portion is in negative pressure state for external perimysium reference atmospheric pressure, because discharge and recharge once produces wild effect, pole in battery
Easily generation gas, the rise of inside battery pressure is Great possibility, so being at the beginning set in inside battery during production battery
Negative pressure state, once internal pressure increase occurs in such later stage battery use, there can be more carrying scopes, and exist
The closed rubber storage chamber of gas is contained, the setting of internal pressure at the beginning is also easier to realize, because gas phase is come for liquid
Say and be easier control pressure.
Further, the closed rubber storage chamber is arranged on the bottom position in outer packing shell body, and it is shaped to flat
Pie, because external package casing top will typically arrange both positive and negative polarity and also have connecting line, narrow space, and bottom position typically can be with
Slot milling, and the closed rubber storage chamber is shaped to flat pie, can maximumlly utilize battery bottom space, no
Interfere the work of remaining part in battery.
Further, the bottom surface of the closed rubber storage chamber is pasted onto external package casing inner bottom surface, can so fix
The position of closed rubber storage chamber, avoids running.
Further, Air-regulating valves are provided with the closed rubber storage chamber, the Air-regulating valves are stretched from external package casing
Go out to outside batteries, when lithium battery interior pressure is too high, closed rubber storage chamber can be adjusted by Air-regulating valves in necessary state
Interior tolerance adjusts the pressure in battery.
Brief description of the drawings
, below will be to embodiment and description of the prior art in order to illustrate more clearly of the utility model embodiment technical scheme
In the required accompanying drawing used be briefly described, it should be apparent that, drawings in the following description are only of the present utility model
Some embodiments, for those of ordinary skill in the art, on the premise of not paying creative work, can also be according to this
