Description
Art
It the utility model is related to the lithium-ion electric core of a kind of lithium-ion electric core, particularly duricrust encapsulation.Lithium-ion electric core is
The core energy storage component of various lithium ion batteries, is widely used in the energy supply of various mobile devices, such as notebook computer electricity
Pond, battery of mobile phone, bluetooth equipment battery, power tool battery, toy battery, there is wide market application space.
Background technology
At present, lithium-ion electric core obtains extensive market application, is common in the lithium battery interior of miscellaneous mobile device.
Common lithium-ion electric core, two kinds can be divided into from the point of view of encapsulation characteristic：One kind is duricrust encapsulation lithium-ion electric core, and one kind is Soft Roll
Polymer lithium ion battery cell.Lithium-ion electric core inner, have by band collector positive pole diaphragm, isolation diaphragm and with collector negative electrode film
Piece passes through winding process, obtains lithium-ion electric core cathode film barrier film negative electrode film assembly, lithium-ion electric core cathode film is isolated
Film negative electrode film assembly is placed into a sealing space, injects electrolyte, lithium-ion electric core is obtained by chemical conversion；Duricrust encapsulates
Lithium-ion electric core housing combination form is common two kinds, and one kind is that positive cover hat cone group is hermetically sealed plus negative pole steel cylinder, another
Kind is that positive pole steel cylinder is hermetically sealed plus cathode cover cap module, two kinds of structure types.
Duricrust encapsulates lithium-ion electric core inner, is that lithium-ion electric core cathode film barrier film negative electrode film assembly is positioned over into lid
In the confined space that cap and steel cylinder are formed, positive pole and the shell positive pole electricity of lithium-ion electric core cathode film barrier film negative electrode film assembly
Connection, the negative pole of lithium-ion electric core cathode film barrier film negative electrode film assembly electrically connect with shell negative pole, are injected in confined space
Electrolyte, metal shell is by means of heat-shrinkable film insulating wrapped.
Because the use condition of lithium-ion electric core is harsh, it is necessary to which special management circuit module carries out Charge Management, put
Fulgurite is managed and safeguard protection, and lithium-ion electric core output voltage changes between 3.0V-4.4V, so plus management circuit mould
Lithium-ion electric core after block, the voltage and current requirement of input and output could be met, just there is safeguard protection, consumption city could be entered
Directly apply field.The duricrust encapsulation lithium-ion electric core that manufacturing enterprise's production at present is dispatched from the factory, is substantially free of management circuit module, so
The duricrust encapsulation lithium-ion electric core product of production must enter back into cell package factory, could enter after increase management circuit module
Market is applied, and this just brings the loss of market versatility, and consumer can not choose at random, certainly as the use of dry cell
By combination and arbitrarily replacing.If duricrust encapsulation lithium-ion electric core solves the general sex chromosome mosaicism in market, output voltage is controlled,
The characteristic of charging and discharging and higher energy density are repeated plus it, and long circulation life advantage, the synthesis of consumer make
The cost using dry cell will be significantly less than with cost, usage experience is more preferable, but also can avoid largely using dry cell big
The discarded environmental nuisance brought of amount, preferably protects environment.
There is part document to be related to management circuit module being placed in the battery container of sealing, solve the electricity of lithium-ion electric core
Pressure and current management and safety protection problem, facilitate consumer directly to use.But its structure type is used Soft Roll polymer lithium
Ion battery core, after managing circuit module in electrical connection, it is encapsulated in the box hat cylinder of sealing, becomes a duricrust encapsulation lithium-ion electric
Core.This structure type, belong to repeatedly encapsulation lithium-ion electric core, significant portion structure space can be wasted, cause space use
Rate declines, so that lithium-ion electric core energy density is largely lost, battery capacity is low, while repeatedly encapsulation causes production cost to increase
Height, make the reduction of its market value.
The content of the invention
In order to overcome existing lithium-ion electric core to cannot directly enter market application field, while solves other technologies scheme
The problem of structure space loss late is high, and production cost is high, facilitate unrestricted choice in consumer's use, independent assortment and freedom more
Change, directly allow lithium-ion electric core to enter consumption market.
The utility model, which employs, after management circuit module Miniaturization Design, to be arranged on duricrust encapsulation lithium-ion electric core
Positive cover cap module internal, consumer can directly use, it is not necessary to consider external circuitses, it is not required that external protection device.
Simultaneously as encapsulating lithium-ion electric core and management circuit module integrated design using by duricrust, electricity has been maximally utilised
Core space, it is possible to improve the energy density of lithium-ion electric core to greatest extent, product is reduced using a packaging technology
Production cost.
Technical scheme is used by the utility model solves its technical problem：The lithium-ion electric core of duricrust encapsulation, just
In polar cap hat cone group, a management circuit module is set, and positive cover hat cone group and negative metal cylinder are by being assembled to form one
Sealing space, sets lithium-ion electric core cathode film barrier film negative electrode film assembly in sealing space, lithium-ion electric core cathode film every
Positive pole and negative pole from film negative electrode film assembly pass through positive cover hat cone group sealing ring and the management circuit in positive cover hat cone group
Module electrically connects, and management circuit module forms positive pole with positive pole block box hat and electrically connected, and management circuit module negative pole passes through positive pole
Block module sealing ring forms negative pole with negative pole steel cylinder and electrically connected.Circuit module is managed by lithium-ion electric core charging voltage and current pipe
Reason and protection circuit, lithium-ion electric core discharge voltage current management and protection circuit, charging and discharging Intelligent Recognition control circuit three
Part is formed.Electrolyte is marked with sealing space, cylinder is outer by means of heat-shrinkable film insulating wrapped.Lithium-ion electric core when being electrically charged,
, can be according to the charging voltage and current value of setting to lithium ion after the managed circuit module management of external charge power supply and control
Battery core cathode film barrier film negative electrode film combines bulk charging, while carries out charging safeguard protection；Lithium-ion electric core in external electric discharge,
Manage circuit module load is carried out can Intelligent Recognition, and discharge voltage and electric current are managed and controlled, ensured according to setting
The specific voltage and current value put externally is discharged output, while carries out electric discharge safeguard protection.
The beneficial effects of the utility model are：Charged and put at the internal positive end of duricrust encapsulation lithium-ion electric core
Fulgurite is managed and safeguard protection, and battery core can work according to the voltage and current parameter set, and product can be directly entered consumption
Market.Due to may be set to the output voltage values and current value of dry cell, the utility model product can be designed as alternative dry electricity
The product in pond, or it is arranged to the application product that can meet other specific uses.
