Abstract
The utility model relates to a battery, especially a polymer battery. This battery includes electric core and outside casing, and the utmost point ear and the contact electricity on the casing of electric core are connected, electric core in roll up the core including a metal, the metal roll up the core and include a metal crate and be located the vertical book core grid of metal crate that electric core is convoluteed and is in book core grid in, the casing be the metal casing, metal crate and metal body case contact. The utility model discloses a polymer battery is through the metal crate coiling electricity core even with rolling up the next rule of core grid, when guaranteeing the large capacity, the appropriate distance that has increased between the electric core book layer, prevented that the heat from assembling in inside, can rapid transmission arrive metal crate with the heat of electric in -core portion through rolling up the core grid simultaneously, and then transmit on the metal casing, from but the rapid transmission of heat to the external environment condition in, the efficiency of polymer battery's heat dissipation is improved, and the service life of the battery is prolonged.
Description
Technical field
The utility model relates to a kind of battery, especially a kind of polymer battery.
Background technology
Along with increasing of present various electronic equipment.The use of battery is also more and more extensive, and according to being used on different products, in numerous battery varieties, polymer Li-ion battery is widely used with the performance of its excellence.Existing polymer Li-ion battery generally comprises the housing of battery core and outside, the lug of battery core and the contact on housing realize being electrically connected, because the present requirement to battery capacity is more and more higher, so the battery core of installing in housing is also more and more intensive, cause battery core tightness more and more higher, heat during battery core work cannot shed in time, the pressure of battery core inside is sharply increased, easily cause bulge, burst, the danger of even exploding.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides that a kind of capacity is large, battery core is rationally distributed, improves the polymer battery of fail safe.
To achieve these goals, the utility model adopts following technical scheme:
Comprise the housing of battery core and outside, the lug of battery core is electrically connected with the contact on housing, its improvement is: described battery core comprises a metal core, described metal core comprises a metal framework and is positioned at the vertical core grid of metal framework, electric core winding is in described core grid, described housing is metal shell, and described metal framework contacts with metal shell.
Preferably, described lug and the junction of contact are provided with insulating barrier.
Preferably, the corner place of described metal framework horizontally outward extends a housing support respectively.
Preferably, described metal framework and core grid are integral type structure.
Preferably, described housing support and metal framework are integral type structure.
Owing to have employed said structure, polymer battery of the present utility model carrys out the winding battery core of regular uniform by metal framework and core grid, ensureing jumbo while, the suitable distance added between battery core volume layer, prevent heat at accumulated inside, the heat of battery core inside can be delivered to metal framework rapidly by core grid simultaneously, and then be delivered on metal shell, from but heat be delivered to rapidly external environment condition, improve the radiating efficiency of polymer battery, extend the useful life of battery.
Accompanying drawing explanation
Fig. 1 is the structural representation of the metal core of the utility model embodiment;
Fig. 2 is the assembly structure schematic cross-section of the utility model embodiment.
Embodiment
As shown in Figure 1-2, the polymer battery of embodiment of the present utility model comprises the housing 2 of battery core 1 and outside, the lug 3 of battery core 1 is electrically connected with the contact 4 on housing 2, described battery core 1 comprises a metal core 3, described metal core 3 comprises a metal framework 31 and is positioned at the vertical core grid 32 of metal framework 31, battery core 1 is wound in described core grid 32, and described housing 2 is metal shell, and described metal framework 31 contacts with metal shell.
Because the metal parts in this battery structure is many and intensive, in order to avoid being short-circuited, in the present embodiment, described lug 3 is provided with insulating barrier 5 with the junction of contact 4.
In order to make the installation of metal framework 31 more stable, reduce the pressure of housing 2 pairs of battery cores 1, in the present embodiment, the corner place of described metal framework 31 horizontally outward extends a housing support 33 respectively simultaneously.
In the general structure of metal core 3, in the present embodiment, described metal framework 31 and core grid 32 are integral type structure; Described housing support 33 is integral type structure with metal framework 32.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
