Description

A kind of battery pack
The utility model relates to a kind of primary cell and combination thereof, belongs to technical field of chemical power.
In recent years, electronic product is to microminiaturized, intelligent, seriation development, and primary cell has also obtained application more and more widely.Many special-purpose series electronic products have proposed special-purpose assorted requirement to primary cell, require its have safety, reliable, the life-span is long, specific energy is high, easy to use, characteristics such as thermal adaptability is good.The used power supply of key device of ciphering startup electronics is exactly an example wherein, and most primary cell can not be taken into account and reaches above-mentioned requirements.
The utility model is to design for the power supply needs that satisfy series electronic products such as key device.
The utility model is achieved by following technical measures:
A kind of battery pack is made up of two monomer primary cells, it is characterized in that, two primary cells are packaged into an integral body, and overall dimension is diameter 34mm, height 64mm, and nominal voltage is 7.2V, and the primary cell shell is provided with safe pressure relief device.
Described monomer primary cell is lithium-thionyl chloride (SOCl 2) the system battery, overall dimension is diameter 33mm, height 31mm, and nominal voltage is 3.6V.
Safe pressure relief device on the described monomer primary cell shell is that place bar shaped is carved and hindered groove.
Primary cell is by formations such as glass insulator, battery cover, lead-in wire, anodal assembly (nickel currect collecting net and carbon black etc. are made), barrier film, negative pole assembly (lithium metal, collector etc. are made), thionyl chloride electrolyte, insulating trip, housing, safe pressure relief device, liquid injection pipes.
Primary cell belongs to the design of limit lithium type, and core body adopts the winding-structure of part lamination.Shell and battery cover are all-sealed structure by the nickel-plated cold-rolled steel plate punch forming.The top is the metal glass envelope, and liquid injection pipe is arranged at the bottom, and anode tap is clipped between housing and the battery cover, and cathode leg is connected with middle tantalum post.All there is the fibreglass diaphragm of porosity 90% core body bottom, top and battery cover inside.The housing side has bar shaped to hinder groove as pressure relief device quarter.
Voltage request according to series electronic products such as key devices, by two monocell stacks, connect with lead-in wire, insulating trip is isolated, above anode weldering positive electrode cap, below a battery bottom weldering negative pole cap, below the anode lead-in wire be welded on the top battery bottom housing, polyester cover and thermal contractible plastic cover by insulation are packaged into one, constitute battery pack.
Overall construction design has guaranteed overall dimension, Li/SOCl 2Selecting for use of system makes this product compare with other electrochemical system products, and under equal service condition, capacity is high 6~8 times, and voltage is high 2 times, discharging voltage balance; Operating temperature range is-45~+ 55 ℃, and a year self-discharge rate is lower than 1.5%, adopts all-sealed structure, guarantees that battery reaches 10 years useful life.Reasonably internal structure and safe pressure relief device have guaranteed the security reliability of this battery pack.
Figure 1 shows that monomer primary cell structure chart: wherein, 1 is thermal shrinkable sleeve; 2 is housing; 3 is barrier film; 4 is the negative pole assembly; 5 is anodal assembly; 6 is pond core insulation sheet; 7 is battery cover; 8 is battery cover built-in electrical insulation sheet; 9 is insulator; 10 is the exterior insulation sheet; 11 is the outside lead sheet; 12 is liquid injection pipe.
Figure 2 shows that the battery pack structure figure of combined integratedization: wherein, 13 is positive electrode cap; 14 is resin; 15 is battery 1; 16 for hindering groove quarter; 17 is the polyester cover; 18 are lead-in wire; 19 is insulating trip; 20 is battery pack thermoplastic cover; 21 is battery 2; 22 is bottom.
Embodiment 1:
The basis battery container is provided with bar shaped and hinders groove 16 as pressure relief device quarter, and liquid injection pipe 12 is a T shape metal tube, is one with welding manner and housing 2 welderings; Weldering is one after battery cover 7 and housing 2 pressings, forms permanent encapsulating structure after the seam of liquid injection pipe collar extension.Anodal assembly 5 ties up to nickel and draws in the net to apply the mixture of being prepared by a certain percentage by carbon black, bonding agent on the base material; Electrolyte system is by SOCl 2With LiAlCl 4Be mixed with the solution that concentration is 1.5mol; Negative pole 4 is the bar shaped assembly that metal lithium sheet and nickel sheet are made, and the bar shaped thin slice that barrier film 3 is made for glass, insulating trip 6 and 8 are the thin discs that the high-quality mica is made; Anodal 5 are folded in half into the strip piece of standard thickness, barrier film 3 are placed be rolled into the core battery case of packing in battery pond between two pole pieces; Positive terminal welding on positive wire and the insulator, negative wire and housing 2 welding form this battery.This primary cell is of a size of diameter 33mm, high 31mm, nominal voltage 3.6V, capacity 4.5Ah.
Embodiment 2:
With two primary cells stacks of making, by the welding of connect at the bottom of the shell of nickel sheet with the positive terminal of a primary cell and another, the centre separates with polypropylene insulation sheet 19, overlaps 17 with the polyester that insulate again and is encapsulated into battery pack.Its characteristic size is: diameter 34mm, high 64mm, nominal voltage 7.2V, capacity 4.5Ah; In 10 years useful life, the requirement of series electronic products such as key device to power supply can be satisfied in working temperature-45~+ 55 ℃.
