Abstract
The utility model discloses a deepwater lithium ion battery with a pressure-proof structure, and the deepwater lithium ion battery has a good using effect. The deepwater lithium ion battery comprises a battery core, wherein a battery shell is sleeved outside the battery core; a battery shell flange is arranged at the upper end of the battery shell; a battery cap is connected with the battery shell flange; and a sealing ring is arranged between the battery cap and the battery shell flange.
Description
Technical field
The utility model relates to and a kind ofly has withstand voltage and lithium ion battery water-resistant capacity for what deep water used, relates in particular to a kind of deep water lithium ion battery with pressure-resistance structure.
Background technology
The lithium ion battery specific energy up to 100-200Wh/Kg, is the highest rechargeable battery of present specific energy, and monomer voltage can reach 3-4V.Make charge carrier because lithium ion battery uses lithium ion, lithium hexafluoro phosphate is made electrolyte, has water funk characteristics.The final assembling of all lithium ions need to be carried out under water-less environment.
Lithium ion battery is according to the difference of external packing, can be divided into box hat, moulds shell, the type such as aluminum hull, flexible package.All packings must be tight, prevents that extraneous wet gas from entering.For the lithium ion battery occasion of using under water, for example submarine, submarine mine, torpedo, scientific investigation equipment under water, the resistance to pressure that improves the lithium ion battery of its use is top priority.As everyone knows, the resistance to pressure of spherical container is best, but is not suitable for the casing of lithium ion battery system.Resistance to pressure next be columniform rotary body.Its main weakness is that cap portion is withstand voltage relatively poor.The resistance to pressure of flexible package system is the poorest.Therefore, if use in the deep water occasion, optimum selection is to use the box hat battery with rotation body structure, can guarantee to have optimum withstand voltage and waterproof effect.If use greater than the deep water of 100 meters in the degree of depth, also must be optimized according to the structure of service condition to cylindrical battery.
Summary of the invention
The purpose of this utility model is to provide the good deep water lithium ion battery with pressure-resistance structure of a kind of result of use.
For achieving the above object, the technical solution adopted in the utility model is: a kind of deep water lithium ion battery with pressure-resistance structure, comprise battery core, the battery core overcoat has battery case, have and it is characterized in that: the upper end of battery case is designed with the battery case flange, the battery case flange is connected with battery cap, is designed with sealing ring between battery cap and battery case flange.
This structure is total, and described battery case lower end is designed with the battery case base, and the bottom surface of battery case base is spherical.
The utility model has the advantages of and be: because the utility model is the most easily causing the battery cap part of pressure penetration, substitute traditional foil type block with the integral battery door block, increase bearing capacity; In the slot rolling part of withstand voltage weakness, make outstanding flange effect with the spinning method, avoid slot rolling district's reduction voltage endurance capability of negative cruvature; Bottom at cylinder, increase the radius of curvature of corner, whole battery case base is processed into round bottom, so the utility model has increased the voltage endurance capability of battery greatly, make it and can use in the profundal zone, outside high pressure gas, water can not enter battery, become to adapt to the lithium ion battery structure that deep water uses, do not increase manufacturing cost, but result of use is improved significantly.
Description of drawings
Fig. 1 is the structural representation of traditional column lithium ion battery;
Fig. 2 is structural representation of the present utility model.
In accompanying drawing: 1, battery cap; 2, sealing ring; 3, battery case flange; 4, battery core; 5, battery case; 6, battery case base.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
The utility model as shown in Figure 1, 2, a kind of deep water lithium ion battery with pressure-resistance structure, comprise battery core 4, battery core 4 overcoats have battery case 5, have and it is characterized in that: the upper end of battery case 5 is designed with battery case flange 3, battery case flange 3 places are connected with battery cap 1, are designed with sealing ring 2 between battery cap 1 and battery case flange 3.In the present embodiment, described battery case 5 lower ends are designed with battery case base 6, and the bottom surface of battery case base 6 is spherical.
This structure utilizes shell structurre to have advantages of maximum voltage endurance capability, and project organization and raising rigidity by optimizing battery make battery have maximum voltage endurance capability.The battery structure that the utility model proposes is easy to processing, and design and moulds of industrial equipment simply, do not change the internal structure of original battery and compound mode, convenience, reliably.When being used for the deep water occasion, can utilize design formula to carry out the parameter combinations design, make it to be applicable to the different degree of depth.
A kind of deep water with pressure-resistance structure is such with the manufacture of lithium ion battery: at first battery core is put into battery case, and negative pole and battery case base is spot-welded together, form negative pole.Then positive pole and the battery cap of battery core is spot-welded together, inject electrolyte, vacuumize electrode solution is adsorbed by battery core.Then battery cap is placed on the flange position, seal compression by mould, make by spinning or bulging die technology during the battery case flange, the base of battery is spherical, has good pressure-resistance structure, namely make the deep water lithium ion battery with pressure-resistance structure described in the utility model, the utility model can be used for the underwater environment of 100-1000 rice.
Battery cap adopts whole machining or forging method manufacturing, and the edge coats polyethylene or polypropylene sealing gasket;
The utility model is cancelled the roller groove structure of traditional cylindrical battery, makes outstanding flange arrangement with spinning method or expanded rubber mould, and the opening of battery is enlarged, and avoids the voltage endurance capability of slot rolling district's reduction battery of negative cruvature;
In the bottom of battery, whole base is processed into round bottom, make it to have shell structurre, increase bearing capacity, this technique can be by spherical mould by the drawing process manufacturing.
Through above technique, the bearing capacity of battery increases considerably.Through test, adopt the 0.5mm box hat, generally can bear 200 meters dark hydraulic pressure and battery performance does not reduce.Adopt 2.0 mm box hats, namely can bear 1000 meters dark hydraulic pressure.
