In the early 1970s, the research work of lithium-ion batteries was promoted due to the energy crisis, and lithium primary batteries with Li or Li-Al alloy as negative electrode materials, including Li/MnO2, Li/I2, Li/SOCl2, Li/FeS2, etc., appeared one after another. In 1970, Japan’s panasonic [...]
Zhu Xuebin, professor of Functional Materials Physics and Devices, Institute of Solid State Physics, Hefei Institute of Physical Science, Chinese Academy of Sciences, has recently made progress in the research of vanadium nitride (VN) supercapacitor materials. The researchers prepared porous VN films on silicon [...]
Thermoelectric materials can convert two of the most widely used forms of energy, heat and electricity, into each other:
By converting electric energy into heat energy, solid refrigeration and temperature control can be realized. Thermoelectric materials have been used in small refrigerators, wine cabinets, high [...]
Solar photoelectric chemistry (PEC) cracking water is an effective method to convert solar energy into hydrogen energy. Among many semiconductor photoanodes, BiVO4 is an excellent photoanode material due to its suitable conduction band, valence band position and forbidden band width. BiVO4 has a light [...]
Due to the effects of diseases, aging, and frequent traffic accidents, the number of cases of bone injury has increased year by year. According to statistics, there are 3 million orthopedic cases in China every year, so the demand for bone substitute materials is [...]
With the widespread popularity of electric vehicles, a lot of friends have been asking questions about power batteries. Shock, as an adventurer, can ignore anything else, but he attaches most importance to the reliability of his adventure equipment. I’m here today with a good [...]
At the Karlsruhe Institute of Technology (KIT), scientists have studied cerium dioxide nanoparticles using probe molecules and a sophisticated ultra-high vacuum infrared measurement system and gained new insights into their surface structure and chemical activity. Their work is reported in three papers in the [...]
Solid-state batteries seem to be getting closer, and the news is endless. Including QuantumScape, in which Volkswagen has held a 5% stake since 2014.
On Dec. 8, publicly traded QuantumScape, a startup backed by Volkswagen and Bill Gates, unveiled the performance of its latest solid-state [...]
