By the time E25 starts to produce manganese battery materials it could well be obsolete.
China is now starting to develop magnesium batteries, one of the problems with current batteries is that they're heavy. Magnesium batteries will be light.
New breakthrough in magnesium metal secondary battery research
According to Science and Technology Daily, recently, the Qingdao Institute of Bioenergy and Processes of the Chinese Academy of Sciences (hereinafter referred to as the Qingdao Institute of Energy) has made new breakthroughs in magnesium metal secondary batteries. It is reported that the solid-state energy system technology center of the institute has carried out a lot of research work on key scientific issues in magnesium batteries, and has achieved a series of achievements in key scientific issues and core materials of magnesium metal secondary batteries, and recently published in the international authoritative journal " German Yinghua, "Advanced Materials" and "Advanced Energy Materials".
With the implementation of the "dual carbon" strategy, new energy has ushered in a leap-forward development. As one of the key equipments that are widely used in the field of new energy, the importance of secondary batteries has received attention from all parties.
Magnesium metal secondary battery application scenarios are expected to expand
Magnesium metal secondary battery refers to a recyclable battery with metal magnesium as the negative electrode. The core of the magnesium metal secondary battery is a magnesium negative electrode, an electrolyte and a positive electrode material that can embed magnesium. Magnesium metal has extremely high volume capacity and is an excellent choice as a negative electrode for high volume energy density batteries.
In terms of practical application scenarios, the research team of Cui Guanglei of Qingdao Institute of Energy has broken through the key technical bottleneck in the manufacturing process of magnesium metal secondary batteries, and has developed a single battery with an energy density of 560 Wh/kg. body battery.
The large-scale application of magnesium metal secondary batteries is still in the early stage of exploration, but it has important potential in improving the safety of secondary batteries, reducing the cost of secondary batteries, and alleviating the pollution of secondary batteries. Partial replacement of lithium batteries or lead-acid batteries in application scenarios.
In the field of new energy vehicles, the application scale of magnesium alloys continues to expand. The Capital Securities Research Report pointed out that the lightweight of automobiles is the general trend of the industry, and the demand for cruising range and safety of new energy vehicles is more urgent for lightweight. In recent years, the amount of magnesium used in my country's automobiles and bicycles has increased from 1.5 kg in 2015 to nearly 5 kg. In 2030, the weight of pure electric bicycles will drop by 35%, and the amount of magnesium used in bicycles will reach 45 kg. In the future, magnesium alloys have a broad market space for lightweight automobiles.
