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.
