Mercury-free Process and Control

(1) to improve the electrical conductivity properties of zinc ointment
Mercury’s “wet” between zinc and zinc help with the collection of fluid connection between the (sticky) Then, to improve the conductivity of zinc ointment, so that the battery has a good anti-vibration performance. Go mercury batteries, the conductivity decreased significantly. Conductive paste to improve the performance of zinc from the use of high viscosity stability Thickening good zinc cream, zinc cream in an appropriate increase in the proportion of zinc in zinc paste and add a few other conductive material aspects.

(2) to control pollution in the production process
Mercury-free alkaline manganese battery production must be kept clean and pollution-free production environment of the production process. According to the battery industry experience, the general requirements for the production of wet conditions at constant temperature, the appropriate temperature of 20 ℃ ~ 28 ℃, humidity 30% ~ 60% (RH). Not suitable for negative electrode assembly assembly at low temperatures, the steel should not be coated graphite conductive at high humidity conditions. Entire production process to be clean, to prevent hydrogen evolution into making zinc impurities increase. Intermittent parts processing, many manual, fittings beyond the control of pollution, the quality can not be assured.

(3) control of carbonated
Effective control of the production process is the carbonation anode are mercury-free alkaline manganese batteries, one of important process measures. First of all, to control the concentration of CO2 in air, zinc ointment preparation conditions in a vacuum, the electrolyte, zinc paste, cathode powder must be sealed packaging, KOH, such as mercury-free zinc powder should minimize exposure to air time, packing damaged should put an end to the use and so on. Sealing process equipment and transfer the former track security guard shall add, to reduce air exchange to prevent the battery carbonated products. Batteries should also be noted that control online time, mercury-free battery production in exceptional circumstances the longest downtime in general may not be more than two hours. The reliability of domestic equipment relatively poor, prone to failure, equipment failure should be to prevent the contingency measures.

(4) the attention of Cu and ultra-fine zinc powder on the impact of mercury-free battery
At alkaline manganese battery copper cathode in the basic state to compound exist in the role of electric potential, the easy migration to the anode, the zinc anode batteries go because of mercury, has accelerated the relocation of ultrafine particles to the cathode, when the diaphragm tube defects have points when, Cu2 + and Zn deficiencies in point happened in the redox reaction, the formation of copper hydroxide crystal sticks gradually penetrate the membrane, forming a short circuit. The production process must be strictly controlled Cu pollution, mercury-free zinc powder in the ultrafine particles there should be restrictions to prevent the migration of zinc powder to form short-circuit the battery.

(5) is more suitable for studies of mercury-free battery capacity requirements and improve the new structure
Made alkaline manganese battery is still the current structure of Japan’s Fuji prevailing on the sealed form, because of mercury-free alkaline manganese batteries Analysis of gas increases, the reliability of such a structure is open to question. Des films with cathode assembly more conducive sealed nylon because of the consistency is better, mercury-free alkaline manganese batteries to consider the reliability of seals from polypropylene nylon than good, unfortunately the high cost of nylon ring. Europe and the United States structure of alkaline-manganese battery is worth drawing on our country, besides a reliable seal, the cell can make use of space has become larger and more conducive to the improvement of battery capacity.

Sanyo rechargeable batteries has been in the market has a good reputation. Not only its own brand of rechargeable batteries (currently mainly Haier to launch the way) sold a great many large manufacturers have used the Sanyo foundry sold their own brand of rechargeable batteries. For example, Sony’s own-brand sales of nickel-metal hydride rechargeable batteries, in fact, is Sanyo’s foundry. And Fuji digital camera with the nickel-metal hydride rechargeable batteries, Sanyo is also OEM products.

However, what the name sounds, a fake then it came. Currently on the market in fake and counterfeit rechargeable battery Sanyo Sanyo OEM other brand rechargeable batteries filled with the supermarkets. One in particular, Sony’s batteries, the largest counterfeit goods. Even have a large number of counterfeit Sony battery you are unable to distinguish them and truly differentiated products.

Take a look at the following three batteries, you can very positive which is false to say it?

Widely recognized by the network to distinguish Sanyo series (including foundry products) battery is as follows:

1, genuine Sanyo rechargeable batteries are a very special area of modeling smooth, round in the square, with a round Fangzhong.

2, genuine Sanyo rechargeable batteries have a cathode surrounded by four symmetrical shape the rules of small holes, and heat-shrinkable film cathode Department smaller parcels, cardboard Cathode paste patch smooth, non-distorted, foaming phenomenon.

3, genuine Sanyo rechargeable batteries have a clear negative small print “HR” Seal and shrink-film wrapped smaller scope.

These are the more common way to distinguish. But now the counterfeit batteries, has produced more realistic. The above three have been unable to discern the.

Take a look at the following comparison of three batteries:

Are the radius of the cathode shape

Cathode surrounded by four symmetrical holes have

Anode have the small print “HR” Seal

Although the conditions are met, but they are not a genuine Sony battery Sanyo foundry. Realistic look at the extent of this fraud, you can rest assured to buy it?

Maybe this big tree is called wind. Sanyo is also OEM rechargeable battery, but only the existence of a large number of Sony counterfeit fakes. Why? Just because Sony sell expensive! Like all OEM products, Sony’s a 2300mAh rechargeable battery expensive than other brands on the dozen dollars or even doubled.

Do not ask me why Sony should You so much, and God knows how Sony is thinking. The face of the present almost everywhere have fake Sony battery situation, I can only advise you: Do not buy Sony!

What does that buy? In fact, since Sanyo and Haier cooperation, in the domestic sales of rechargeable batteries on all to do the Haier. As long as we look for the signs with Haier Sanyo rechargeable batteries, they will not买到假货. I recommend the following which the Sanyo 2500mAh rechargeable batteries. Except to continue to check the above three points, there is little to look for:

The battery side of outsourcing has clear shrink film 6 Seal batch number. Before the four figures represent the production date, the latter two for the letters or numbers / letters combination.

At present, such a genuine Sanyo 2500mAh battery are generally allowed to 20 yuan / section to buy. This is the Sanyo introduced the largest-capacity Ni-MH AA rechargeable batteries. As a result of great sales, but also reasonable prices, coupled with continued strong crackdown Haier measures, Zhongguancun many digital stores are in sales. At present, Sanyo has not re-launch of OEM products such 2500mAh capacity, rather than to buy those who have been unable to identify the authenticity of counterfeit brands, such as do not buy Sanyo’s own brand.

In addition, domestic such as super, etc. PISEN own brand of rechargeable batteries also have a very good quality and more favorable prices. We also recommend that the digital players more choices of domestic brands, reducing the possibility.
