The stagnation of battery technology has become the biggest bottleneck for limiting the variety of products. Whether it is a smartphone or an electric car user, it will face the problem of battery life anxiety. Whether it is mobile equipment, hybrid or electric vehicles, lithium-ion batteries are currently the most mainstream solution, although in terms of actual performance, performance does not make us very satisfied.Although researchers have not yet invented a new technology that can be commercially promoted, as the world's number one car manufacturer, Toyota has also begun to "break the heart" of battery technology, Toyota said that magnesium can make batteries It's smaller, longer lasting and more durable, and has the potential to be used in both smartphones and the automotive world! ! !Magnesium is more stable than lithium, so this means that it can be used more inside the battery, and it can make the battery more capacity. The fluctuation of metal lithium needs to be embedded in the graphite rod to make the battery work normally, and if the lithium is reduced. The amount of material used, in contrast, to conserve energy is also reduced.However, magnesium also has its own problems. First of all, there is no electrolyte suitable for magnesium metal. Usually liquid electrolyte. Usually, liquid electrolyte is the medium for electron transfer between the two stages of the battery. It also converts the chemical energy inside the battery into Electrical energy.To solve this problem, it is necessary to develop different types of energy storage technologies. Toyota's chemical engineers have shown that hydrogen can be used as a material for preserving lithium ions. Toyota is now very mature in hybrid technology, so it has arrived. Actively develop the stage of hydrogen fuel cells.Of course, like any new research, Toyota's research is just in its infancy, and there is still a long way to go between the lab and the actual commercial. Toyota has already admitted that it wants to apply magnesium to the battery field. And to reach the hands of consumers, at least 20 years.

According to the latest news in the market, the ferrosilicon price of large-scale manufacturers in the northwest region continued to increase, with an increase of 1,000 yuan/ton, and the price of ferrosilicon 72# was 12,800 yuan/ton including factory acceptance. The price of ferrosilicon 75# was 13,000 yuan/ton. .Since December, not only the price of ferrosilicon has skyrocketed, but other raw materials for magnesium metal production, such as dolomite, solvent, magnesium chloride, fluorite, and even rock wool and sulfur powder, have risen in price due to the shortage of spot stocks in winter. , so that the original magnesium production costs remain high. According to the current price of ferrosilicon of 9,500 yuan, the original magnesium cost is still at a high level of over 18,000, and the magnesium plant has a serious loss. In addition, the current magnesium ingot market is weak, and the wait-and-see mood is serious. The magnesium plant is in a dilemma. Under the weight of the double pressure of cost and sales, some magnesium plants in Fugu began to reduce production twice. It is understood that manufacturers that reduce production by more than 50% are: Tianyu, Jin Wantong, Tianlong, Xintian, Huashun, Founder, Zhongxin, Dongxin, Wanxin. The remaining magnesium plants also have different levels of production cuts. The original production in the Fugu area was about 1,400 tons per day. Due to the rising factors of raw materials such as ferrosilicon, the current daily output of the Fugu area is less than 900 tons per day.The Fugu Magnesium Association has learned through research that the current inventory of magnesium ingots is less than 15,000 tons. Due to the implementation of the production reduction strategy in most enterprises, there is no significant increase in inventory. At present, the mainstream price of the Fugu market includes taxed cash of 15,500 yuan / ton, including tax acceptance of 15,800 yuan / ton, the number of transactions is not large. It is related to the wait-and-see attitude of the purchaser, but it is not ruled out that the magnesium factory is reluctant to sell because of the serious cost. In the current magnesium market, the magnesium plant suffered a serious loss and its operating conditions were worrying. If the magnesium price remains unchanged, unless the price of ferrosilicon falls below 7,000 yuan. If the price of ferrosilicon is still firm at more than 9,000 yuan / ton, if the price of magnesium ingots does not reach 17,000 yuan / ton, some magnesium plants have made the worst plans, and are planning to cut production again or even completely stop production to reduce losses.

The waste gas generated during the high-temperature smelting process is converted into heat energy for office and daily use through a set of waste heat recovery devices, which can be used for heating and using hot water for hundreds of people. On January 19th, the reporter learned in Fuyang Meilixin Technology Co., Ltd. (referred to as the company) that the waste heat recovery unit can save the company 1 million yuan per year.As an auto parts manufacturer, Meritor's products include engine blocks, automatic transmission housings, etc. The main raw materials for these products are aluminum ingots. Wang Minghu, the company's equipment minister, said that only when the temperature of the furnace is raised to more than 800 degrees Celsius, the solid aluminum material can be melted. It is understood that in many enterprises, the residual heat of the furnace is discharged into the air along with dust and smoke. “We developed and designed a waste heat recovery device at the end of the furnace to convert the high-temperature evaporated waste into thermal energy for office and living,” said Wang Minghu.On the morning of January 19, the reporter saw in the company's die-casting workshop that the workers placed a car of aluminum into the elevator next to the furnace, waiting for the system to automatically transport the aluminum material to the furnace. The company has four furnaces, each with a waste heat recovery unit. In the small attic next to the die-casting workshop, the reporter saw that one of the waste heat recovery devices was connected to the furnace on one side and the water circulation system on the other, and the isolated dust and ash were collected centrally. Wang Minghu said that the hot air left by the waste heat recovery device will enter the water circulation system. "The company's winter heating and the use of hot water for more than 500 employees all year round have been solved."The reporter then went to the company's staff quarters, free to unscrew a faucet, touch the water temperature, and found it to be hot. Liu Hongxia, an employee of the company's logistics department, said: "The company supplies hot water 24 hours a day, whether it is working water or going back to the bedroom after work, and turning on the faucet with hot water." "Not only the full use of energy, but also achieved Zero emissions.” Wang Minghu said that if the company's production capacity increases in the future, it can also increase the income of the company by erecting pipes to transfer excess heat energy to surrounding residential communities.Wang Minghu told reporters that the burn rate of the company is about 2% lower than that of other companies in the same industry. “When the waste heat recovery unit is put into use, the company’s carbon dioxide emissions are reduced, and the amount of natural gas required for furnace combustion is The month has also decreased by 2%."
