Are these ones ocean disposable like lead acid batteries?
These types of batteries are called wafer batteries because you just eat them
It’s wafer thin
Someone’s gotta charge the eels.
Damn. I had to look up the SI prefix scale to make sure i got this right. 100 microwatts would be 0.1 miliwatts. If they truly do end up releasing a 1 watt version of this battery, it would be fucking perfect for meshtastic nodes. Currently, the most common radios used in those nodes transmit at 22 dBm, which is about 150 milliwatts. In client mute mode, the radio by itself transmits one packet every six to eight minutes on average. A 1W battery should constantly run the node without ever having to charge it or, even if not, only have to charge it extremely rarely. I’m not sure how long it takes to actually transmit a packet, but assuming it takes a minute per packet, which I think would be incredibly unlikely, then it would transmit seven times per hour if it transmitted every five minutes and would use about 21.4 milliwatts. As efficient as the NRF-52 chip is, I suspect it is the thing that’s taking up most of the power.
So you’re saying that if I buy about 500 million of these I can use them to charge my electric car?
Read the article guys, yes it is extremely low amperage how ever they are meant to be used in parallel, as you would expect, you use this right now in real life applications I don’t see the niche part but 5 cels the size of a nikle can power most iot micro nodes.
yay nuclearwaste for everybody 🥳
