Researchers have achieved a major advance in the development of materials suitable for on-chip energy harvesting. By composing an alloy made of silicon, germanium and tin, they were able to create a thermoelectric material, promising to transform the waste heat of computer processors 💻 back into electricity. ⚡ With all elements coming from the 4th main group of the periodic table, these new semiconductor alloy can be easily integrated into the CMOS process of chip production. The research findings made it onto the cover of the scientific journal ACS Applied Energy Materials. 𝗛𝗼𝘄 𝗱𝗼𝗲𝘀 𝗮 𝘁𝗵𝗲𝗿𝗺𝗼𝗲𝗹𝗲𝗰𝘁𝗿𝗶𝗰 𝗲𝗹𝗲𝗺𝗲𝗻𝘁 𝘄𝗼𝗿𝗸? A thermoelectric element converts temperature differences directly into electrical energy. When there is a temperature gradient across a thermoelectric material, it induces a flow of charge carriers, generating electricity. This process can be used to capture and recycle waste heat in electronic devices, converting it back into usable energy and reducing overall energy consumption. For thermoelectric materials, lower thermal conductivity is desirable because it allows for a greater temperature gradient, which is essential for efficient energy conversion. GeSn alloys, with their reduced thermal conductivity, excel in creating this gradient, enhancing their thermoelectric performance.

"A research team has successfully enhanced the performance and durability of all-solid-state batteries. This breakthrough was made possible through the implementation of a novel approach known as bottom electrodeposition. Their research has been published in Small. Secondary batteries generally rely on liquid electrolytes when used in various applications, such as electric vehicles and energy storage systems. However, the flammability of liquid electrolytes poses a risk of fires. This prompts ongoing research efforts to explore the use of solid electrolytes and the metal lithium (Li) in all-solid-state batteries, offering a safer option. In the operation of all-solid-state batteries, lithium is plated onto an anode, and the movement of electrons is harnessed to generate electricity." #solidstatebatteries #batterytechnology

New strategy for high-performance cathodes in aqueous zinc ion batteries A new strategy was proposed in the field of aqueous zinc-ion battery to help increase the capacity of the cathodes, making them more efficient, according to a recent study published in ACS Nano. "We converted low-valence vanadium into high-valence vanadium in oxides using an electrochemical method," said Prof. Linhua (Steven) Hu from the 中国科学院合肥物质科学研究院 (Hefei Institutes of Physical Science, Chinese Academy of Sciences, who led the team. Aqueous zinc-ion batteries (AZIBs) are a promising technology for large-scale stationary energy storage. To make this technology more viable for commercial use, researchers have developed innovative cathode materials to improve performance. Vanadium oxides (VOx) have been widely considered a favorable option for AZIBs. However, their low electronic conductivity and slow Zn2+ diffusion kinetics have posed challenges in demonstrating the dominance of VOx. In this study, the researchers constructed an in situ electrochemically induced phase transition to obtain high-performance aqueous zinc ion cathode materials. They used a special process to change the structure of a material called V6O13 to V5O12·6H2O when it was first charged. ---This change made the material better at conducting electricity and allowed the zinc ions to move more easily, increasing its ability to store energy.--- The modified material also had spaces that made it easier for particles to move around, and it remained stable over many charging cycles. As a result, the new material could be charged very quickly, had a high energy storage capacity, performed well at high charging rates, and lasted a long time without losing its ability to store energy. ---This new method provides a new direction for solving the challenges in developing high-performance cathodes for AZIBs, according to the team.--- by ZHANG Nannan, Chinese Academy of Sciences
