Panasonic Industry has introduced compact surface-mount electrolytic polymer hybrid capacitors that are “one size smaller than ZC series with the same capacitance” and AEC-Q200 compliant for automotive use, it said. Called the ZL series, the parts come in five case sizes from 5mm diameter (ø) x 5.8mm high (47 or 82μF), to 10ø x10.2mm (470 or 680μF). There are two ...
Microsoft and the US Pacific Northwest National Laboratory (PNNL) have teamed up in a multi-year project to explore material science using AI and super-computing, and discovered a promising solid electrolyte for lithium-ion and sodium-ion batteries as a proof-of-concept. The multi-step process used to search for possible electrolytes reduced a list of 32 million inorganic materials to 18 in 80 hours, ...
New ion conductivity science has been revealed during research into a better electrolyte for solid-oxide and proton ceramic fuel cells, according to Tokyo Institute of Technology (TItech). The material is actually a ‘dual-ion conductor’, which allows both protons and oxide ions to defuse, and can “realise high total conductivity at lower temperatures and improve the performance of electro-chemical devices”, according ...
A single capacitor can influence the lifetime and quality of entire electronic devices. These components wear out relatively easily and are used in virtually all circuits, including power supply modules, filters and voltage converters. Therefore, it is worth getting familiar with a range of brand-name components, such as Panasonic products, designed to ensure long-lasting and reliable operation. Nowadays, it is ...
Japan’s National Institute for Materials Science (NIMS) and the Tokyo University of Science have created a solid-state electric double layer neuromorphic transistor, claiming it to be the fastest yet, and proving its computational ability by training it to convert waveforms. “The team measured the speed at which the transistor operates by applying pulsed voltage to it, and found that it ...
NSPE-HC from NIC Components is a series of AEC-Q200 automotive-grade surface mount aluminium electrolytic capacitors. In five case sizes from 6.3 x 6.3mm diameter to 12.8 x 10mm diameter, the series covers 56 to 560μF in ratings of 25 and 35Vdc, with operation over -55 to +105°C and a load life rating of 5000 hours at +105°C. “The performance of ...
Copper is the key to low-cost electrochemical cells that emit blue and white light, according to the Technical University of Munich and the University of Turin, which have used deep data analysis to guide their research. By using statistical tools and other methods on over 90 similar copper-based compounds (of the form Cu(N^N)(P^P)) that have been used in light-emitting experiments, the team ...
Elastomer electrolytes might be the answer to safe lithium-metal batteries, according to researchers at the Georgia Institute of Technology. Batteries using lithium metal anodes rather than lithium ions promise high capacities, but a tendency to grow internal cell-shorting spike-like metal dendrites makes them a risky, or even unsafe, proposition if liquid electrolytes are used. Solid inorganic or polymer electrolytes can ...
Panasonic is promising long life from a range of surface-mount aluminium electrolytic capacitors. The parts span 10 – 680µF, 6.3 – 50Vdc and come in radial cases from 6.3mm in diameter and 7.7mm tall to 10mm dia and 10.3mm tall. Operation of the capacitors, dubbed V-FH, is across -55 to +105°C and life at maximum temperature is 10,000 hours in all ...
Lithium sulphur cells can retain >95% Coulomb efficiency for 80 charge cycles at >300Wh/kg, according to the Hong Kong University of Science and Technology, which is working on a novel cathode design. The electrochemistry of lithium paired with sulphur (a low-cost material) make the combination desirable for lightweight high capacity batteries, but the elements, so far, are not happy bedfellows. “There ...
