This sounds similar, but solid-state, and without using gold. They do not explain how it is supposed to last hundreds of charge cycles, but they have not figured out how the gold ones work!
Scientists are working on rechargeable batteries with almost infinite lifetimes - ScienceAlert
"The first: microscopic vulnerabilities in the structure of the battery material steer the lithium ions haphazardly through the cell, eroding the battery in seemingly random ways, much like rust spreads across imperfections in steel."
Here's why your phone and laptop batteries degrade so fast - ScienceAlert
"Huawei says it has managed to bond special heteroatoms to the graphite molecules in the anode section of the battery to get this process moving faster, without decreasing energy density or battery life."
This new battery charges 10 times faster than the one in your smartphone - ScienceAlert
"a fair chunk of battery drain is actually caused by bugs and inefficiencies due to insomniac-style apps that wake up and simply can’t go back to sleep when it’s their rightful bedtime."
The code is available for free, but not as an app yet.
This code can help you get an extra 16% smartphone battery life - ScienceAlert
"the device's party trick is being able to reduce the time a phone's components spend searching for a signal and making a connection, and its makers say that could lead to an energy saving of up to 45 percent."
but manufacturers would rather have smaller antennae (and cases).
This new smartphone antenna could do wonders for battery life - ScienceAlert
Ouch! "phones integrated with the StoreDot technology would cost up to $150 more than the average smartphone does now, and would be able to handle around 1,500 recharge cycles for a three-year lifespan."
This new battery can fully charge your smartphone in 30 seconds - ScienceAlert
"the Nikola Lab device has an antenna that picks up the ambient waves. It then uses what's known as a rectifier circuit to convert the alternating current into a direct current, which it puts back into the phone. "It's actually working off the energy of the phone itself," he says."
New smartphone case charges your phone by harvesting electricity from the air - ScienceAlert
This one channels light outside of the visible range to photovoltaic receptors at the edges:
New transparent solar cells can be used on windows, smartphone screens - ScienceAlert
"If you're getting tired of announcements about breakthroughs in battery technology, that's understandable:"
Ha! I will stop there!
Researchers create lithium-air battery that could be 10x more powerful than lithium-ion - ScienceAlert
