Chapter 104 Application of silver in the field of new energy

Silver has the best light reflection efficiency and polishability of all metals, and is an indispensable core part in solar concentrator applications.At the same time, silver is an excellent catalyst. After being mixed with semiconductor materials, it can greatly improve the efficiency of converting solar energy into electrical energy, and the energy output can be increased by 12%.The rapid development of solar technology will generate thousands of tons of silver demand in the world every year. Batteries will become the core element in the era of green environmental protection, and silver batteries will be the best candidates to replace traditional lithium batteries.Its duration is 40% higher than that of lithium batteries, and there is no danger of lithium batteries being explosive. 95% of the parts are completely recyclable, which has important environmental value.Silver batteries have extremely broad application prospects in computers, mobile phones, hearing aids, medical equipment and all mobile electronic devices.It has great application prospects in spacecraft, deep-sea detectors, torpedoes, missiles, submarines, etc.

The widespread civilian use of silver batteries is still in its infancy, but it represents the trend of a new generation of environmentally friendly battery technology in the future.Considering how widely used battery technology is, the overall increase in demand for silver would be staggering. In 2017, 25.9 billion RFID chips will use silver, and the rapid expansion of radio frequency identification (RFID) technology around the world will bring silver applications into a new field.The introduction of Chapter 6 has specifically introduced the great use of RFID technology for tracking and positioning. The RFID chip is embedded with a micro-coupling circuit and an antenna to receive the electromagnetic wave emitted by the card reader. The energy carried by the electromagnetic wave forms a current in the coupling coil and "reads" the unique ID information on the chip, and then the ID information is read by the antenna. Transmit back to the card reader.In this way, the card reader about a few hundred meters away is like a long-range ID detection radar, which can confirm that the chip is within its detection range.Once these remote ID detection radars form a network ranging from shops and schools to communities, cities, and even the whole country, all the carriers of RFID chips in this huge network will be located and tracked in real time. The technology of the Internet of Things is built on the basis of RFID technology.

In July 2010, Wal-Mart announced the widespread use of RFID to manage its huge inventory to reduce costs.Once the effect is good, Wal-Mart will fully popularize the application of RFID in its 3,500 American chain stores, and its global suppliers will also be required to use the same technology to interface with Wal-Mart's inventory system. According to US IDTechEx company estimates, RFID chips will expand rapidly around the world at an astonishing rate of 93% per year.By 2017, the annual output of RFID chips in the world will reach a staggering figure of 25.9 billion pieces!And 10.9 milligrams of silver is used on each chip, which cannot be recycled at all due to its tiny content.

In the future, 2,400 tons of silver will be consumed annually in the field of wood protection in the United States. On September 11, 2003, the "Committee on Forest and Public Land Management" of the U.S. Senate submitted the "Public Land Output Research Act".The bill is committed to replacing the currently widely used copper-containing wood preservation technology. The toxic double salt formed by copper arsenate and copper acetate produced by this technology is seriously harmful to the environment and has attracted increasing attention in the United States.Silver has a natural antibacterial effect, and as a wood preservative material, it can resist termite erosion, growth and decay of spore fungi, aquatic organisms' boarding, and other insects' parasitism and reproduction.The vast majority of residential houses in the United States are made of wood. Once this technology is officially introduced into the American wood preservation market, the wood preservation field in the United States alone will consume 2,400 tons of silver every year!

Apparel applications will be one of the biggest future demands for silver. Silver is a natural inorganic antibacterial material. Inorganic silver antibacterial materials have the characteristics of persistence, persistence and broad spectrum, good heat resistance, high safety, and no drug resistance. Silver ion materials are commonly used in the desert combat uniforms of the U.S. military to sterilize and deodorize.The same goes for sportswear, as silver kills most of the bacteria in sweat that is the main source of all kinds of odors and lesions.The silver-plated clothing can still keep the smell fresh and healthy even when you sweat a lot in the wild and cannot be washed for a long time.In the field of clothing alone, silver has become the largest single application field, consuming 1,200 tons of silver every year.

This number is just the beginning of Baiyin's entry into the clothing field.Just imagine, if 1.3 billion Chinese clothing consumers also start to wear healthy clothing containing silver ions, and 1 billion Indians join this trend, what will be the demand for silver? ! In the field of food packaging, packaging materials such as food, beverages, and milk containing silver ions can greatly extend the shelf life.Silver ion bactericidal materials are also used in drinking water filtration devices. At the same time, swimming pools across the United States will also abandon the chlorine gas sterilization method with serious side effects and use silver bactericidal materials instead.

At present, the annual global industrial consumption of silver is about 30,000 tons, and the huge emerging silver consumption market has just begun. There is an important difference between silver and gold, that is, silver has a wide range of industrial uses. Therefore, the industrial consumption of silver is much larger than that of gold.Another important feature of silver is that most of the various applications in the industrial field are trace applications. For example, the integrated circuits of mobile phones contain trace amounts of silver worth a few cents, and LCD large-screen color TVs are also coated with trace amounts of silver. It is not difficult to find trace amounts of silver in all household electronic devices.Even when the price of silver soars 10 times, such a trace amount of silver application, it is difficult to have a noteworthy impact on the final product price.

In addition, silver is used in a small amount in industry, which makes it impossible to effectively recover silver after industrial application, and thus it is lost forever. Silver's excellent multiple properties and huge application space make it the leader with the most explosive price among all metals! People who do not understand the monetary properties of silver often refer to silver as an industrial metal, which is an obviously misleading term.Could it be that if people find that gold can be used to set dentures, will it change the monetary properties of gold?A large number of industrial uses and a small amount of non-recyclable consumption will not damage the rare and precious quality of silver, but it is an important evidence of its higher investment value.The accurate title of silver should be a rare monetary metal with a large number of industrial uses.
