(Summary description)In June 2009, a piece of news caught everyone's attention: Sony Corporation announced the commercialization of 6 models of alkaline mercury-free button batteries (LR), which means that Sony's mercury-free button batteries will soon be comprehensive Bring to market.

In fact, as early as 8 years ago, China's battery company Xinlida Battery Co., Ltd. broke through this difficult problem that plagued the world before other countries and took the lead in mass production.

The mercury in the battery is extremely harmful to humans, because the mercury in the battery has a significant toxin effect on the brain and nervous system and interferes with the normal work of the nerves. Exposure of high doses of mercury to the fetus or infant can cause mental retardation and cerebral palsy. Hearing impairment or vision loss. Even exposure to low doses of mercury can affect children's healthy growth, potentially causing them problems with attention, coordination of action, language skills, visual space, and word memory. For adults, chronic mercury poisoning can cause memory loss, convulsions, vision loss, and paralysis of the hands and toes, and can have adverse effects on fertility and blood pressure. Increasing evidence also suggests that exposure to mercury may increase heart disease.

由于 Due to the high frequency and universality of the battery, the threat of mercury-containing batteries is more prominent. It is reported that 600,000 liters of water can be contaminated by a miniature mercury-containing alkaline button battery, which is equivalent to a person's drinking water in a lifetime.

Over a decade, famous battery manufacturers in Japan, the United States, and Europe have done a lot of research on mercury-free button batteries. However, there are still technical problems that cannot be solved, and no company has been able to successfully produce alkaline mercury-free button batteries, which has caused the use of mercury-containing alkaline button batteries in the global market. Billions of button batteries are produced and used every year, leaving people in China and the rest of the world at risk of exposure to mercury.

When all the research work came to a standstill, this problem was solved by New Leader Deqing Company. In this regard, both the China Battery Industry Association and the United States Environmental Protection Organization have given high recognition and evaluation as a huge contribution to the world's environmental protection cause. With the invention of this technology, China has also become the first country in the world to solve the problem of mercury-free button batteries.

It is understood that the reason that mercury is contained in button batteries is that mercury is used to block the battery's negative zinc paste from contacting the metal of the negative plate, because this contact will generate hydrogen, which will cause the battery to swell and deform, leak or even explode. The early mercury-containing button batteries also had leakage problems. This was the most fatal flaw that affected battery life and performance. However, as early as the late 1970s, the leakage of mercury-containing button batteries had passed the The negative cover, which was originally “punched from thin steel plate and then plated with nickel or gold”, was replaced with a negative cover made of “composite metal strip” made of nickel, stainless steel, and copper composite rolled. And other related improvement measures to be effectively controlled.

的 The purpose of the invention of this patent is to realize the mercury-free of the button battery on the basis of maintaining the anti-leakage performance of the original mercury-containing (that is, mercury) button battery.

This patent was filed by the patentee to the State Intellectual Property Office on October 19, 2001, and was authorized by public announcement on October 2, 2002. The patent number is 01234722.1.

With the increasing use and waste of mercury-containing button batteries, the mercury in waste batteries has become increasingly polluting the environment. Therefore, for the needs of environmental protection, the button battery manufacturing industry has been eager to solve the problem of mercury in batteries. Prior to the application of this patent, Sony, Toshiba, Hitachi, Panasonic, Seiko and other Japanese companies that are leading the industry in the development and manufacture of button batteries have made various attempts to solve the problem of mercury-free button batteries. Efforts have been made to propose various technical solutions. All these technical solutions are devoted to solving the new leakage problem caused by amalgamation, but they have not been able to effectively achieve the technical effects of both amalgamation and anti-leakage. Therefore, until the filing date of this patent, the button battery manufacturing industry actually has not effectively solved the technical problem of both mercury-free and leakage resistance, so mercu

This patent was filed by the patentee to the State Intellectual Property Office on October 19, 2001, and was authorized by public announcement on October 2, 2002. The patent number is 01234722.1.
 
With the increasing use and waste of mercury-containing button batteries, the mercury in waste batteries has become increasingly polluting the environment. Therefore, for the needs of environmental protection, the button battery manufacturing industry has been eager to solve the problem of mercury in batteries. Prior to the application of this patent, Sony, Toshiba, Hitachi, Panasonic, Seiko and other Japanese companies that are leading the industry in the development and manufacture of button batteries have made various attempts to solve the problem of mercury-free button batteries. Efforts have been made to propose various technical solutions. All these technical solutions are devoted to solving the new leakage problem caused by amalgamation, but they have not been able to effectively achieve the technical effects of both amalgamation and anti-leakage. Therefore, until the filing date of this patent, the button battery manufacturing industry actually has not effectively solved the technical problem of both mercury-free and leakage resistance, so mercury-free button batteries have not yet achieved industrialization and entered the market.
 
This patent successfully solves this technical problem that has plagued the button battery manufacturing industry for many years through the use of ultra-conventional research and development ideas. Prior to the filing date of this patent, all technical improvement solutions to solve the problem of non-mercury were made from nickel-stainless steel-copper in the prior art in order to slow down the rate of negative electrode creep (ie, liquid leakage). The anode cover made of three-layer metal composite plate is improved. All these improvements do not involve any changes to the laminate structure of the anode cover, even if the laminate structure of the anode cover is known to be misaligned during stamping. In order to damage the indium or tin coating applied to suppress the generation of hydrogen and cause battery bloating and leakage, it still only proposes other complicated "plugging" schemes without giving any information about Technical inspiration to solve this problem by changing the laminated structure of the negative electrode cover.
 
However, this patent takes a different approach. Its research and development idea surpasses conventionally the negative cover with a laminated structure made of three-layer metal composite plates in the prior art, but directly replaces the negative electrode made of iron or stainless steel sheets. On-chip "tests of gold, silver, copper, tin, indium, etc., and finally found that the indium or tin plating on the negative electrode sheet successfully controlled the gas generated when the battery negative zinc paste contacts the negative electrode sheet, plus the improvement of raw materials and formulas. An alkaline zinc-manganese, zinc / silver-manganese button-type battery containing no mercury was made on the ground. Based on this discovery, the present utility model was completed. "
 
In the technical solution proposed by this patent, in order to better plate indium or tin on the negative electrode sheet, and eliminate the pinhole problem that easily occurs in a single plating layer, this patent proposes to bare the negative electrode sheet made of iron or stainless steel sheet. Nickel or copper is first plated on the sheet to make a "battery negative electrode plated with nickel or copper," and then indium or tin is plated on the negative electrode plate of the battery.
 
The mercury-free button cell manufactured using this patented technical solution has successfully achieved industrialized production for a long time in 2002, and the product entered the market on a large scale. It has been purchased and used by well-known companies such as McDonald's and has won praise from relevant US environmental protection organizations. It has achieved technical goals that Sony, Toshiba, Hitachi, Panasonic and other multinational companies have failed to achieve for many years, and made a strong contribution to protecting the human ecological environment.
