New battery-free technology can power devices using ambient RF signals (nus.edu.sg)
Ubiquitous wireless technologies like Wi-Fi, Bluetooth, and 5G rely on radio frequency (RF) signals to send and receive data. A new prototype of an energy harvesting module – developed by a team led by scientists from the National University of Singapore (NUS) – can now convert ambient or ‘waste’ RF signals into direct current (DC) voltage. This can be used to power small electronic devices without the use of batteries.

Aluminum batteries outlive lithium-ion with a pinch of salt (ieee.org)
Electric vehicles( EVs) and green energy sources rely heavily on batteries to store electricity. Currently, more than 75 percent of the world’s energy storage depends on batteries that contain lithium, an expensive mineral that’s subject to volatile pricing. Lithium-ion (Li-ion) batteries themselves can be volatile, too, because they use a flammable electrolyte that can catch fire when overcharged.

Automatic DIY polarity-independent AA battery charger (hackaday.io)
SPINC is an Open-Source NiMH charging station that can automatically load and eject AA battery cells. Simply drop batteries into the top of the device, regardless of their polarity. The internal mechanism picks up one cell at a time and fast-charges them sequentially. Up to 7 fully charged batteries can be conveniently stored inside the device for easy access. In addition, SPINC doubles as a desk clock, displaying the date and time on its high-resolution LCD.

Why Aren't There B Batteries? (2022) (thebatterygenie.com)
The “B” battery is a type of vacuum tube battery. It is used to provide constant and positive plate voltage and is colloquially referred to as a “dry battery.” The “B” battery was a high-voltage battery commonly used for antique tube radios. It was available in various sizes and shapes, with a voltage range of 45 to 90 volts. Unfortunately, B batteries are now scarce to find, as very few vendors still sell them in some African and European countries.
