Description

A kind of manufacture method of low self-discharge battery
Technical field
The present invention relates to a kind of manufacture method of low self-discharge battery.
Background technology
The primary cells such as alkaline Mn cell, lithium pyrite battery, lithium thionyl chloride cell, lithium fluorocarbon battery have that specific energy is high, storage period long (self discharge is low), leakproof can wait well advantage, become the requisite driving powers of consumable electronic product such as electronic radio frequency identification system, Tire Pressure Monitor System, electronic toy, circuit main board, electronic interpreter.But it is that specific power is poor that primary cell has a larger defect, and heavy-current discharge capacity attenuation ratio is very high, if ER26500 battery 20mA discharge capacity is that 9Ah, 100mA current discharge capacity is only 4Ah.
Specific energy is high owing to having for nickel-cadmium cell, power-performance strong (can big current fast charging and discharging), high security and the reliability and durability characteristic of wide warm area and tool has been widely used, and is widely used in the fields such as electric tool, railway, Aero-Space, stand-by power supply, startup power supply.But, nickel-cadmium cell has higher self discharge, shelves before reusing after charging for a long time, again need carry out activation charging to battery, therefore need at some the equipment field shelving and don't possess charge condition for a long time, conventional nickel-cadmium cell cannot meet instructions for use.
Summary of the invention
The object of the present invention is to provide a kind of low self-discharge cadmium-nickel storage cell, can the nickel-cadmium cell of continuous discharge after shelving for a long time, be applicable to the big current environment for use battery situation that cannot meet next time.
The invention provides a kind of both positive and negative polarity electrode group that comprises and be received nickel-cadmium cell in a reservoir together with electrolyte.Described electrode group forms by reeling or superposing nickel hydroxide positive plate plate, barrier film and cadmium hydroxide negative plate.Described nickel hydroxide positive plate plate is that sintering forms, and nickel hydroxide positive plate plate contains cobalt and cadmium element by dipping; Described cadmium hydroxide negative pole is electrodeposited electrode, comprises cadmium hydroxide and nickel plated steel strip; Described barrier film is comprise sulfonic polypropylene film and the composite membrane containing polyacrylic film through oleum sulfonation process; The aqueous solution of described electrolyte only containing NaOH.
According to said method, described nickel hydroxide sintering positive pole thickness is 0.25mm ~ 0.7mm;
According to said method, described cadmium hydroxide electro-deposition negative pole thickness is 0.2mm ~ 0.7mm;
According to said method, in described electrolyte, the mass percentage of NaOH is 10% ~ 60%, and proportion is 1.20g/L ~ 1.45g/L.
Significantly can be reduced the self discharge of battery by the synergistic action effect of described each inscape according to nickel-cadmium cell of the present invention.After the charging of this battery, experience more than 3 years shelve for a long time, before reusing, do not need charging to get final product continuous discharge.
