What is the difference between a magnesium battery and a lithium ion battery?

What is the difference between magnesium batteries and lithium-ion batteries? In the past 10 years, lithium-ion batteries have dominated consumer electronics and electric vehicles. But some people believe that magnesium batteries may change the rules of the game. In the future, this will make the battery life of our smartphones and other devices longer. For equipment manufacturers, magnesium is 96% cheaper than lithium, and the use of magnesium batteries can significantly reduce production costs. What is the difference between a magnesium battery and a lithium ion battery? A lithium ion battery is a battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. The lithium metal battery was first developed and researched by Gilbert. Lewis in 1912. In the 1970s, Watson proposed and began to study lithium-ion batteries. Due to the very active chemical properties of metal lithium, the processing, storage and use of metal lithium have very high requirements on the environment. Lithium ion batteries can be divided into two categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain metallic lithium and can be recharged. Magnesium batteries are primary batteries with magnesium as the negative electrode and certain metal or non-metal oxides as the positive electrode. Among the existing varieties, there are mg-mn dry batteries similar to ordinary zinc-manganese dry batteries, which can be discharged at any time; there are also spare batteries, which can be stored for a long time in a dry state and used immediately after activation by adding water. The structure of mno2 dry battery is similar to that of cardboard zinc-manganese battery. The composition and ratio of the mno2 positive carbon package are basically the same. The negative electrode is a magnesium cylinder. Magnesium batteries have high energy, with an energy density of 800 watt-hours per kilogram. The storage life of magnesium storage batteries can reach more than 10 years. It can be activated for temporary use on any occasion by adding water or sea water. It can be used within half an hour after activation. The working voltage is very stable, and the service life is generally 0.5-24 hours. Lithium-ion batteries are far in second place. Magnesium has several advantages over lithium. The melting point of lithium is about 180 degrees Celsius, while the melting point of magnesium is about 650 degrees Celsius, which makes it safer and more abundant than lithium. However, the development of magnesium batteries faces some technical problems, such as the lack of suitable cathode materials and the lack of stable charge and discharge. The biggest advantages of magnesium batteries related to lithium-ion batteries are as follows. JPG1. Magnesium batteries are relatively safe. During charging and discharging, magnesium dendrites will not appear on the negative electrode. 2. The content of magnesium is richer than lithium, and the price is relatively cheap; 3. Compared with lithium, magnesium has a higher melting point and boiling point (648°C/1170°C), relatively inert chemical properties, and easy processing; 4. Magnesium batteries are still under development In the early stage, there is no proper systematic report on electrolyte, positive electrode and negative electrode materials. It is estimated that there is still a long way to go. The advantages of magnesium batteries are as follows: raw material advantages: my country is the world's largest producer of primary magnesium, accounting for 70% of the global market. my country is an important producer of primary magnesium in the world, with sufficient primary magnesium production capacity, sufficient competitiveness, low prices, and an international market. my country's primary magnesium producing areas are mainly distributed in Shanxi, Ningxia, Liaoning and other places. Product cost advantage: The price of magnesium batteries is two-thirds of that of lithium-ion batteries of the same size. Production technology advantages: Through the assessment of relevant technical departments, its production technology indicators are better than those of Israel and Germany. Product performance advantages: Magnesium batteries have higher energy (equivalent to three times the volume of lithium-ion batteries, nickel is ten times more than ten times that of lead-acid batteries and batteries), small size, light weight, large capacity, and long storage life. Wide operating temperature range, wide range of application areas, great price advantage, environmental protection and pollution-free, secondary recycling characteristics. Independent intellectual property rights: The inventor of magnesium batteries is a well-known expert in this field in my country. His intellectual property has been patented and passed the examination. He is currently waiting for a two-year confirmation process. Its patented technology can be immediately applied to business processes. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
