There is infinite kinetic energy around our lives. Piezoelectric materials help to fully absorb, store, and use all kinds of mechanical kinetic energy, completely changing the way people interact with nature. Silicon-based piezoelectric materials are usually in the crystalline state and can effectively convert various types of minute mechanical kinetic energy into the required electrical energy. When external mechanical kinetic energy is applied to the piezoelectric material, the internal charge of the material is rearranged to form a potential difference. The most typical piezoelectric material application is a lighter ignition device that converts mechanical kinetic energy of the finger into spark energy.
Piezoelectric material technology combined with nanotechnology, such as nanowires, nanosheets or nanosheets, the biggest advantage lies in the compatibility, flexibility and wearability of electronic microchips, which can simultaneously realize all kinds of digital, electronic, and pressure Electricity, energy storage and other functions. The EU Research Council (ERC) provides full funding of 2 million Euros. The European SINERGY research team led by Dr. Murillo of the National Microelectronics Center of Spain (NMC) has long been dedicated to nanostructured smart piezoelectric sensing technology. The development and application. The current R&D and innovation activities mainly focus on the research and development of Airbus's intelligent piezoelectric sensor, and have achieved a number of technological breakthroughs. With more than 6,000 types of sensors inside the aircraft, interconnected cable cabling and high operating and maintenance costs, wireless transmission and piezoelectric material sensing technology can efficiently provide low-cost energy-saving energy storage solutions.
The nanostructured piezoelectric material sensor combined with the microchip has a wide application prospect in the field of daily digital electronic products. The research team has established two start-up companies and is engaged in the commercialization and application of smart piezoelectric sensor sensors. It has successfully entered the smart grid, intelligent transportation, smart homes and smart cities and other industries.

The excellent SEI film is incompatible with organic solvents, allowing lithium ions to freely enter and exit the electrode while solvent molecules cannot pass through, thereby preventing the co-insertion of solvent molecules from damaging the electrode and improving battery cycle efficiency and reversible capacity. It is mainly divided into inorganic film-forming additives and organic film-forming additives. With the help of the electron-withdrawing effect of halogen atoms, the ability of the central atom to obtain electricity is improved, so that the additives can be reduced under higher potential conditions and effectively passivate the electrode surface to form a stable SEI film.
