Li–S batteries could become next-gen energy storage
Energy storage systems with high energy density are essential to fulfilling the ever-increasing demands of electronic devices, electric vehicles, and smart grids for intermittent solar or wind power. The Li-S battery is a promising candidate for next-gen energy storage, with an extremely high theoretical energy density that is five to seven times higher than that of conventional LIBs.
Towards safe and durable lithium-sulfur batteries
Safety has always been a major concern for electric vehicles, especially preventing fire and explosion incidents with the best possible battery technologies. Lithium-sulfur batteries are considered as the most promising candidate for EVs due to their ultra-high energy density, which is over 5 times the capacity of standard commercial Li-ion batteries. This high density makes it possible for electric vehicles to travel longer distances without sto...

Experiments reveal promising nitride semiconductors
Researchers use simulations to identify previously undiscovered semiconductors with promising attributes for optical and electronic applications. A nitride among those proposed has been successfully fabricated using high-pressure synthesis and is found to emit red light. The discovery of new semiconducting materials is a scientifically and technologically important issue; state researchers in Japan in a recent report.
PIM simplifies low-EMI design in ATCA applications
Expanding its 3E PIM (Power Interface Module) family that are compliant with the industry-standard quarter-brick footprint, Ericsson Power Modules has announced the PIM4610PD. This module has been optimised to simplify design in blade server applications based on ATCA and PICMG 3.7 systems and is also highly suited to server and storage systems in any industrial, telecomms and datacomms application that employs either distributed power or interme...
Optimising electron transfer in solar fuel devices
Researchers at the University of British Columbia and the University of North Carolina at Chapel Hill have discovered a new way to optimise electron transfer in semi-conductors used in solar fuel solutions. The finding, published in Nature Chemistry, could have a big impact on devices that convert sunlight into electricity and fuel. Researchers have already shown that the efficiency of electron transfer at semi-conductor interfaces depends on the...
Device turns body motion into power source
A combined team of researchers with members from several institutions in China and the Georgia Institute of Technology, has developed a flexible nanogenerator that harnesses the energy from moving body parts and uses it to run electronic devices. In their paper published in the journal Science Advances, the team describes their new device, how they made it bendable, and the ways they believe it might be used.
60V N-channel MOSFET offers industry's best resistance
Texas Instruments has introduced a 60V N-channel FemtoFET power transistor that provides the industry's lowest resistance, 90% below traditional 60V load switches. Reducing power loss in end-systems. The CSD18541F5 is offered in a tiny 1.53x0.77x0.35mm silicon-based package that has an 80% smaller footprint than load switches in SOT-23 packages.
