Microscopic dendrites of sodium hydrogencarbonate a.k.a. baking soda, viewed under a do-it-yourself smartphone-based microscope 🔬 in reflected white light.
"The cathode is not made from the familiar mixture of #lithium and other metals. Instead, the primary ingredient is #zinc, which ranks as the fourth most produced metal in the world.
Eos’s batteries use a #water-based electrolyte (the liquid that moves charge around in a battery) instead of organic solvent."
This is intended to be a #GridBattery.
Dendrite formation is the bane of lithium batteries.
"In the new research, Li and his team stop #dendrites from forming by using micron-sized silicon particles in the anode to constrict the lithiation reaction and facilitate homogeneous plating of a thick layer of #lithium metal."
