Ionic Battery Maker
New Member
I thought I would share some of my progress here since people seem to care about battery tech in this community. I've been working on zinc ion batteries for almost 2 years now as a side home research hobby. I honestly encourage people to do the same, it's a really satisfying hobby, and I feel I've made some pretty significant progress.
Zinc Ion: This battery chemistry is nothing new, but it's highly underrated and for some reason no longer pursued in most battery research anymore. As you can see I've achieved near 200 watt hours per kg energy density based on active material(Not cell weight since this is a lab cell). This battery is fully rechargeable and some scientists have achieved 10k cycles with only 10% loss. My personal record is 200 cycles at around 10% loss. That said my focus hasn't been on longevity since I am still making energy density improvements, that will become a main focus later when I am getting diminishing returns on energy and power.
If anyone is interested, I have an old instructional video on how to make these, though the battery in the video is around half the energy density I am getting now. I plan to post more videos soon:
