OK, but is the energy density comparable?
"His team built a working battery with this material, albeit with a lower conductivity than similar prototypes that use more lithium."
I do know that because of Ohm's law, this directly translates to less available current than conventional electrolytes. There's not enough info to determine mAh though.
Yeah, batteries internal resistance is a huge factor in their usability and the speed they charge.
Especially in the modern day where a lot of their use is towards high amperage applications like cars.
People need to understand tho, Lithium batteries are usually only about 11% lithium, Lithium Ion batteries are mostly Cobalt and other metals. So at most you're replacing 6% of a batteries total mass.
Mostly cobalt is also not accurate. There's a small part of cobalt in some batteries.
Other like LiFePo are cobalt free.
All energy density is comparable. That’s what makes it energy density.
comparable adjective Similar or equivalent.
pedantic adjective Being finicky or fastidious, especially with language.
