Lithium metal battery with flexible Lithium lanthanum zirconium oxygen LLZO electrolyte sheet

Researchers at Tokyo State University have developed a new method for preparing flexible ceramic electrolyte sheets for lithium-metal batteries. They mixed garnet ceramics, polymer binders and ionic liquids to produce a quasi-solid, flake electrolyte. The synthesis is performed at room temperature, requiring much less energy than existing high-temperature (>1000°C) processes. It can operate over a wide temperature range and is a promising battery electrolyte for, for example, electric cars. Fossil fuels account for most of the world’s energy needs, including [...]

Less than 10,000 tons a year worldwide,High performance aluminum nitride powder is difficult to produce,why?

Aluminum nitride (AlN) ceramics have good thermal, electrical, mechanical and chemical stability, and are now more ideal substrate materials and electronic packaging materials. The excellent performance of AlN ceramics is directly related to the performance of raw material powder, and the high performance AlN powder is the key to prepare high thermal conductivity AlN ceramics. In foreign countries, the manufacturing process of AlN powder has been quite mature and the commercialization degree is also very high. Previously, according to the [...]

Sodium titanate holds graphene together to create a high energy, high power micro capacitor

With sea urchin sodium titanate as the negative pole and porous activated graphene as the positive pole, what kind of “spark” will be generated when they combine? According to the dalian Institute of Chemical Physics, Chinese Academy of Sciences, wu Zhongshuai’s team and Bao Xinhe’s team worked together to combine “sea urchins” with graphene to develop flexible sodium ion micro-supercapacitors with high energy density and high heat resistance.

The high precision isotope ratio analysis of ultramicro strontium samples can be realized by using silicotungstic acid as the emitter

Strontium isotope ratio (87Sr/86Sr) has been widely used in earth science, astrochemistry, environmental chemistry, food origin tracing, archaeology and other fields. Since the 1960s, the Thermoelectric ionization mass spectrometer (TIMS) has been regarded as the benchmark technique for ratio analysis of 87Sr/86Sr with excellent accuracy and high sensitivity. Excellent sensitivity is the prerequisite for the analysis of high precision 87Sr/86Sr ratio in ultramicro samples. The key to improve the sensitivity lies in the selection of suitable emitters to improve [...]
