Abstract
The invention relates to the battery manufacturing technical field, and particularly relates to a method for improving performance of a square aluminum-shell battery. The method includes the following steps: injecting an electrolyte into the battery; carrying out high-temperature standing of the battery injected with the electrolyte; carrying out rapid formation of the battery; carrying out high-temperature aging of the battery; and carrying out test screening of the battery product. Under a condition of high workshop environmental humidity (45%-60% RH), and by changing the formation electric current and time value, a battery pole piece is ensured to have a good formation effect while rapid and efficient formation is performed, and thus the capacity and the lifetime of the battery are improved; and the method has smaller influence on the product performance, has the product qualified rate more than 95%, and has quite strong popularization and application values.
Description
Technical field
The present invention relates to battery manufacture technical field, especially a kind of method of improving square aluminum housing battery performance.
Background technology
Battery is one of articles for daily use in our live and work; At present, the kind of battery has varied; And institute's employing method has much relations in the quality of battery and its manufacturing process, relate in particular in the manufacture process of aluminum-shell battery, in the situation that ambient humidity is high, its performance and product qualified rate are had to very large impact, urgently to be resolved hurrily.
Summary of the invention
The object of the present invention is to provide a kind of can humidity be under 45%-60%RH condition, manufacture, the efficient chemical synthesizing method that improve aluminum-shell battery performance of product qualified rate more than 95%.
To achieve these goals, the present invention adopts following technical scheme:
An efficient chemical synthesizing method that improves aluminum-shell battery performance, comprises the steps:
A method of improving square aluminum housing battery performance, comprises the steps:
The first step, inside battery inject electrolyte.
Second step, by noted electrolyte battery high-temperature leave standstill.
The 3rd step, battery is changed into fast.
The 4th step, battery is carried out to high temperature ageing.
The 5th step, battery finished product is carried out to test screen.
Further, in described second step, at the temperature of 45 ± 3 DEG C, leave standstill 8-12 hour.
Further, in described the 3rd step, first 0.15C fills 1 hour, then 0.2C fills 2 hours.
Further, in described the 4th step, aging 48-72 hour at the temperature of 45 ± 3 DEG C.
Owing to having adopted such scheme, the present invention can be under the condition of workshop condition humidity high (45%-60%RH), by change forming current and time value, in rapidly and efficiently changing into, ensure that battery pole piece has good formation effect, thereby improved capacity and the life-span of battery; Less on properties of product impact, product qualified rate, more than 95%, has very strong promotion and application and is worth.
Brief description of the drawings
Fig. 1 is the method flow diagram that the embodiment of the present invention provides.
Embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are elaborated, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
As shown in Figure 1, a kind of method of improving square aluminum housing battery performance of the present embodiment, comprises the steps:
The first step, according to production engineering specifications, inject corresponding electrolyte at inside battery.
Second step, quiescence in high temperature, make electrolyte at battery positive/negative plate and barrier film depth of penetration, meanwhile, cell reaction material infiltrated fully.
The 3rd step, change into fast, make the battery can be in film forming under low-voltage, also for battery film forming is more abundant.
The 4th step, high temperature ageing, reduce the polarization of inside battery by high temperature ageing, the second permeation that simultaneously carries out electrolyte infiltrates, and ensures the performance performance that battery material can be better stable.
The screening of the 5th step, finished product test, this is that test battery capacity, internal resistance, voltage are exactly to classify according to customer requirement turnover finished product, chooses defective products.
Further, as an aspect of the embodiment of the present invention, in second step, at the temperature of 45 ± 3 DEG C, leave standstill 8-12 hour; The too short meeting of infiltrating time causes infiltration insufficient, and infiltrating time is long can affect the adhesive effect of active material on foil.
Further, as an aspect of the embodiment of the present invention, in the 3rd step, first 0.15C fills 1 hour, 0.2C fills 2 hours again, with 0.15C charging within 1 hour, be mainly for battery can be in film forming under low-voltage, with 0.2C fill within 2 hours, be mainly for battery film forming more abundant, time is 3 hours altogether, can greatly reduce battery and cause water suction long the depositing of external environment of high humidity.
Further, as an aspect of the embodiment of the present invention, in the 4th step, aging 48-72 hour at the temperature of 45 ± 3 DEG C, the control time, the long excessive high temperature storage of material that easily causes caused capacitance loss, and the control time, too short meeting caused infiltrating time deficiency.
This method can, under the condition of workshop condition humidity high (45%-60%RH), by change forming current and time value, ensure that in rapidly and efficiently changing into battery pole piece has good formation effect, thereby improve capacity and the life-span of battery; Less on properties of product impact, product qualified rate, more than 95%, has very strong promotion and application and is worth.
The foregoing is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention and accompanying drawing content to do; 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 invention.
