Research Bits: May 9


Optical oscilloscope Researchers from the University of Central Florida developed an optical oscilloscope to measure the electric field of light. The high speed at which light oscillates has made reading its electric field challenging, with current instruments able to resolve an average signal associated with a pulse of light rather than individual peaks and valleys within the pulse. “... » read more

Research Bits: April 19


Processor power prediction Researchers from Duke University, Arm Research, and Texas A&M University developed an AI method for predicting the power consumption of a processor, returning results more than a trillion times per second while consuming very little power itself. “This is an intensively studied problem that has traditionally relied on extra circuitry to address,” said Zhiy... » read more

Research Bits: April 13


Washable battery Researchers from the University of British Columbia developed a washable, flexible, and stretchable battery. “Wearable electronics are a big market and stretchable batteries are essential to their development,” said Dr. Ngoc Tan Nguyen, a postdoctoral fellow at UBC’s faculty of applied science. “However, up until now, stretchable batteries have not been washable. Th... » read more

A freeze-thaw molten salt battery for seasonal storage


New research paper from Pacific Northwest National Laboratory. Abstract "Grid-level storage of seasonal excess can be an important asset to renewable electricity. By applying the freeze-thaw thermal cycling strategy, here, we report Al-Ni molten salt batteries with effective capacity recovery over 90% after a period of 1–8 weeks as a proof-of-concept. We explore three activation methods... » read more

Microstructural impacts on ionic conductivity of oxide solid electrolytes from a combined atomistic-mesoscale approach


Academic paper from Lawrence Livermore National Laboratory (LLNL) scientists in collaboration with San Francisco State University and the The Pennsylvania State University. Abstract "Although multiple oxide-based solid electrolyte materials with intrinsically high ionic conductivities have emerged, practical processing and synthesis routes introduce grain boundaries and other interfaces t... » read more

Native lattice strain induced structural earthquake in sodium layered oxide cathodes (batteries)


Abstract "High-voltage operation is essential for the energy and power densities of battery cathode materials, but its stabilization remains a universal challenge. To date, the degradation origin has been mostly attributed to cycling-initiated structural deformation while the effect of native crystallographic defects induced during the sophisticated synthesis process has been significantly ove... » read more

Advancing Electric Vehicle Battery Characterization By Integrating Drive Cycle On Cooling Impacts


Battery powered electric vehicles (EVs) and hybrid electric vehicles (HEVs) have been gaining market share as the public’s environmental concerns drive the demand for better fuel efficiency. Apart from the need to improve the mileage one can drive before recharging, battery reliability is another major concern. Effective cooling in intense charge/discharge conditions is crucial to minimizi... » read more

Realizing The Future Of Fast EV Charging Through CoolSiC Based Topology Design


While consumers are keen to reduce their carbon footprint, the move to E-Mobility, especially private electric vehicles (EV), is hindered by the limited charging infrastructure, most notably in fast charging. This white paper reviews the charging landscape and examines implementation approaches for fast DC chargers. Specific focus is placed on chargers delivering 350 kW and more for fast electr... » read more

New Ways To Improve Batteries


Researchers around the world are racing to develop more efficient, denser, and safer battery technology, and they are reaching far beyond where research has gone before. Much of this is being driven by concern over exhaust from internal combustion engines, which are responsible for a significant portion of global CO2 emissions. Nearly all carmakers today have announced plans to develop batte... » read more

Batteries Take Center Stage


For any mobile electronic device, the biggest limiting factors are the size, age, type, and utilization of the batteries. Battery technology is improving on multiple fronts. The batteries themselves are becoming more efficient. They are storing more energy per unit of area, and work is underway to provide faster charging and to increase the percentage of that energy that can be used, as well... » read more
