Description
Technical field
The utility model belongs to battery technology field, more particularly to a kind of low temperature lithium battery.
Background technique
Lithium battery is high with voltage with it, energy density is high, have extended cycle life, storage time is long, environmental protection and light-weight etc.
No matter many merits are widely used in size electrical equipment.But low temperature lithium battery reaches to the every field in application
To preferable working effect, discharge capacity is improved, encapsulation must be just carried out to lithium battery.
Application No. is 2016212999444 Chinese patents to disclose a kind of double film soft package lithium batteries, though it solves existing
The problem of encapsulation, but be not very well, to need to make improvements in the heat-proof quality for lithium battery, so that it is met encapsulation
It is required that and meeting heat-insulated requirement.
Utility model content
The purpose of this utility model is just to provide a kind of low temperature lithium battery, can be fully solved above-mentioned the deficiencies in the prior art it
Place.
The purpose of this utility model is realized by following technical proposals:
A kind of low temperature lithium battery, including lithium battery electric core, the surface encapsulation of lithium battery electric core have interior encapsulating film, interior encapsulating film
Surface be provided with insulating layer, insulating layer is connected with shell, and insulating layer includes micro-nano thermal insulation layer and thermal isolation film, and shell includes waterproof
Layer and flame-retardant layer, interior encapsulating film connect micro-nano thermal insulation layer, and thermal isolation film connects waterproof layer.
Further, the interior encapsulating film includes tinfoil paper layer and the HDPE layer that is connected with tinfoil paper layer, and HDPE layer connects lithium electricity
Pond battery core, tinfoil paper layer connect micro-nano thermal insulation layer.
Further, the flame-retardant layer is using flame-retardant layer made of flame retardant rubber.
Further, insulating layer is provided between the electrode tip of the lithium battery electric core and interior encapsulating film, insulating layer and shell.
Compared with prior art, the utility model has the beneficial effects that: structure is simple, design rationally, is solved existing
The problem of technology, can not only play good packaging effect, while be conducive to prevent lithium battery electric core heat dissipation, and raising is put
Electricity.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Appended drawing reference: lithium battery electric core 1, interior encapsulating film 2, micro-nano thermal insulation layer 3, thermal isolation film 4, waterproof layer 5, flame-retardant layer 6, electricity
Extreme 8, insulating layer 9.
Specific embodiment
The utility model is further described with attached drawing combined with specific embodiments below.
As shown in Figure 1, a kind of low temperature lithium battery, including lithium battery electric core 1, the surface encapsulation of lithium battery electric core 1 have interior envelope
Film 2 is filled, interior encapsulating film 2 includes tinfoil paper layer and HDPE (high density polyethylene (HDPE)) layer being connected with tinfoil paper layer, and HDPE layer connects lithium
Battery battery core 1, tinfoil paper layer are connected with insulating layer.Insulating layer connects shell, and insulating layer includes micro-nano thermal insulation layer 3 and thermal isolation film 4, shell
Body includes waterproof layer 5 and flame-retardant layer 6.Tinfoil paper layer connects micro-nano thermal insulation layer 3, and micro-nano thermal insulation layer 3 connects thermal isolation film 4, and thermal isolation film 4 connects
Water layer 5 is taken over control, waterproof layer 5 connects flame-retardant layer 6.The preferably flame retardant rubber flexible of flame-retardant layer 6 is made, such as the core outsourcing of electric wire
The flame retardant rubber layer covered.
Wherein, tinfoil paper layer is masking foil, and the thermal insulation property of masking foil is preferable.Micro-nano thermal insulation layer 3 uses micro-nano thermal insulation board system
At it is a kind of heat-barrier material that thermal coefficient is extremely low that thickness, which is preferably 0.3-1cm, is conducive to keep internal temperature of battery not
It is distributed.In order to further ensure that safety, between the electrode tip 8 and interior encapsulating film 2, insulating layer and shell of lithium battery electric core 1
It is provided with insulating layer 9, avoids electrode tip 8 short-circuit.
The utility model structure is simple, and design rationally, solves problems of the prior art, can not only play good
Packaging effect, while being conducive to prevent distributing for 1 heat of lithium battery electric core, improve the discharge capacity of its low temperature lithium battery.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
