Antimony-carbon anode could pave the way for developing next-gen batteries

May 04, 2019 -

Potassium is an abundant mineral that possesses similar redox potential as lithium. Researchers have been investigating potassium-based batteries as replacements for lithium-ion energy storage systems that have plateaued in terms of potential.

However, potassium also suffers from drawbacks. It has a large ion radius and it reacts rather slowly. As such, the anodes of potassium-ion batteries can only handle limited amounts of energy and degrade rather quickly.

Fast charging actually strengthens zinc-ion cells, defying decades of scientific dogma

August 26, 2025 - anode in sharp, tree-like microscopic spikes called dendrites. Over repeated charging cycles, these spikes grow like roots, eventually piercing the battery's internal separator. This piercing creates a short circuit, rendering the battery useless and posing a safety risk.

Conventional wisdom, borrowed from lithium-ion research, held that fast charging would exacerbate this problem. The logic was simple: Pumping more current into the battery would cause zinc to deposit ...
