Japan is a highly developed industrialized country. Since the 1960s, it has been bravely climbing the peak in the research and development and application of new energy technologies. This is not only due to its rich scientific research resources and talent pool, but also Japan's numerous policies on energy conservation and emission reduction in recent years and the environmental awareness of the whole society. Recently, some media reported that a Japanese company has successfully developed a new type of battery with a capacity eight times higher than that of existing batteries. Let us see whether this will promote changes in the new energy market.
1. Basic introduction of "new battery"
It is reported that the research team of The University of Tokyo in Japan has recently developed a rechargeable magnesium-ion battery, whose capacity is 8 times that of the existing lithium-ion battery, and the weight and cost of the battery are also half of the lithium-ion battery with the same capacity. . According to the team, this magnesium-ion battery is a method in which magnesium ions interact with electrode materials to store and release energy. Since magnesium ions have more electrons and ions, magnesium-ion batteries can store more energy and have more efficient performance than lithium batteries. The company is currently working to further improve the stability and commercial production capacity of this battery.
2. Will "new batteries" affect the new energy market?
As we all know, batteries are the core of new energy technologies. Whether a battery with high energy gap, high safety and reasonable price can be found is directly related to the development and popularization of new energy technologies. In the past, the new energy vehicles and energy storage industries continued the pattern of lithium-ion batteries. Although various new battery technologies have been widely used in different fields, such as sodium-ion batteries, gas batteries, supercapacitors, etc., lithium-ion batteries still have irreplaceable advantages in terms of cost, energy storage density, and reliability. , so there is no new type of battery with a subversive trend that threatens the hegemony of lithium-ion batteries.
Against this background, however, The University of Tokyo has developed this new battery technology that may bring about significant changes. The first is the ability to store more energy. With the rapid development and popularization of new energy vehicles and energy storage markets, batteries with large capacity and high performance will be highly important. Compared with the existing lithium-ion batteries, the increased capacity of magnesium-ion batteries can undoubtedly greatly improve the use time and efficiency of equipment. Second, the new battery reduces cost, is lighter, and is easier to layout for new energy vehicle and energy storage system designs. Especially for the power industry in outlying islands, remote areas and other power-deficient areas, new batteries may become a viable alternative comparable to fuel-fired power generation.
3. Looking forward to the possible problems of "new batteries"
However, it is worth noting that although the new battery has excellent performance, it is in an unstable scientific research stage. The industrialization of new batteries must pass large-scale engineering and technical application tests before they can truly enter the stage of commercialization. In addition, the research and development of "new batteries" also requires a large amount of capital investment to obtain breakthroughs in high-quality battery raw materials, battery manufacturing equipment, and production standards.
At the same time, this new type of battery has potential safety hazards. Based on existing data, the voltage of magnesium-ion batteries is relatively high, and excessive charge and discharge times or higher than the specified charging current are likely to cause dangerous situations such as fire or explosion. Compared with mature lithium-ion batteries, the safety of magnesium-ion batteries is unknown, and the reliability has not been fully verified.
Overall, the development of new battery technologies and new energy markets are inseparable. New type batteries will dominate the new energy vehicles and energy storage market in the future. However, the risks and uncertainties in the entire field call for this type of battery to go through rigorous research and experiments, so as to overcome existing problems and improve Scientific research capabilities and improving the innovation system to promote the further development of new energy technologies are important issues that researchers need to think about urgently. In this unprecedented period of energy transition, I hope that domestic enterprises can also speed up the pace of energy conservation, emission reduction and green development, and spend more time, thought and funds on the research and development of new energy technologies, and make more contributions to the transformation of the global new energy pattern. contribute.
