When a lithium battery is about to reach the end of its life, a new molecule can be injected into it to restore its original charging capacity. It can even allow a battery that can only guarantee 6-8 years/1000-1500 charge and discharge cycles to maintain 10,000 charge and discharge cycles, and the battery health level is almost the same as when it left the factory. The relevant research results were recently published in the journal Nature.

At present, there are two main ways to produce hydrogen from solar energy. One is to use solar cells to generate electricity and then electrolyze water, which is highly efficient but the equipment is complex and expensive; the other is to use sunlight to directly decompose water, that is, to use semiconductor materials such as titanium oxide to "one-click" decompose water molecules under sunlight.

High-temperature alloys refer to a type of metal material with Fe, Co, and Ni as the matrix that can serve for a long time at high temperatures above 600°C. They need to withstand high temperature, high pressure, complex stress, and oxidative corrosion working conditions. They are widely used in aerospace engines, gas turbine turbine discs, turbine blades and other hot end components. Among them, Ni-based high-temperature alloys are the most widely used.

The most common application of rare earth fluorides is the raw materials for preparing rare earth metals and alloys by calcium thermal reduction and molten salt electrolysis. For example, in the process of preparing lanthanum, cerium, praseodymium-neodymium and dysprosium-iron alloys by molten salt electrolysis, lanthanum fluoride, cerium fluoride, praseodymium-neodymium fluoride and dysprosium fluoride are important components of molten salt. In the process of preparing medium and heavy rare earth metals such as yttrium, Terbium and dysprosium by calcium thermal reduction, yttrium fluoride, terbium fluoride and dysprosium fluoride are one of the indispensable raw materials.

Ytterbium metal has excellent photoelectric properties, such as low work function, high transmittance, relatively high stability and low surface plasma effect. Most rare earth metals react with hydrogen to form trihydrides and break and pulverize, while ytterbium only forms dihydrides under low pressure, which are smaller in size and do not break, which is conducive to the application of hydrogen and its isotopes; within 0 ~ 4 GPa, ytterbium metal will not change phase, and has a high piezoresistance coefficient. It is the best material for pressure sensors and has very important applications in blasting measurement and protection engineering.

As the lightest metal structural material in practical applications, magnesium alloy has the advantages of high specific strength, specific stiffness, good electromagnetic shielding and dimensional stability, and no pollution. Commonly used commercial magnesium alloys have good formability and room temperature strength, but their heat resistance is still poor. Therefore, it is necessary to develop high-strength and heat-resistant magnesium alloys to meet the needs of different usage environments.

Rare Earth acetate is widely used in catalysis, corrosion inhibition, luminescence, batteries and medicine, showing huge development space. Rare earth acetate crystals will not get wet and stick in the air, and have excellent water solubility and good thermal stability. With the deepening of research on rare earth acetate, rare earth acetate will play a more important role in the field of industrial materials.

As functional modified materials, rare earth elements play a key role in many links of the new energy industry. The innovative development of new rare earth materials is of great significance for improving the production conversion efficiency of new energy, optimizing storage and transmission efficiency, and serving new energy terminal equipment.

Since modern times, mankind has experienced three industrial revolutions, the essence of which is the innovation of energy and materials. The emergence of intelligent equipment driven by artificial intelligence technology has turned the driving force into green renewable energy, greatly liberating human productivity, which also indicates that the "intelligent" era is coming. This energy revolution will bring about all-round innovation in energy production, energy storage, energy transmission and energy terminal use.
