Anyone for potassium ion batteries?

Potassium can work with graphite in a potassium-ion battery, claims Oregon State University, which said the last time this possibility was explored was in 1932.

“For decades, people have assumed that potassium couldn’t work with graphite or other bulk carbon anodes in a battery,” said chemist Xiulei Ji…

Updated: Fairchild puts current control into LLC PSUs

Fairchild has launched an isolated dc-dc controller chip which adds current-mode control to LLC resonant power supplies.

Called FAN7688, it has ‘charge current control’, instead of the voltage mode control traditionally used for LLC. “This “allows for tighter and faster output regulation against load transients and also simplifies…

UK firm harvest ambient RF for IoT

Ambient RF signals are a viable source of energy, claims UK-based Drayson Technologies, which has patented a technique to harvest them.

Branded Freevolt, it uses an antenna, ‘non-linear device’, RF filter and a power manager (PMM in diagram).

“To integrate Freevolt into different devices, Drayson Technologies has developed…
