Most renewable energy researchers are focusing on a type of battery called a flow battery for storing energy, in which electricity is stored in a tank of liquid electrolyte. However, making this technology cost-effective on the scale required for the power grid has proven challenging.
Researchers at Berkeley are helping with this problem through the development of an affordable battery membrane, which is the part of the battery that separates the cathode and the anode. Traditional fuel cells use a fluorinated membrane, but these membranes are expensive and aren’t designed for a flow battery. The researchers have created a new type of membrane specifically for flow batteries made from polymers called AquaPIMs, or aqueous-compatible polymers of intrinsic microporosity.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
