Jakarta — Potassium-ion batteries could become a key player in the green transition, offering a cost-effective and abundant alternative to lithium-ion technology, according to a recent review by researchers at Dongguk University in South Korea.
The study, published in Science and Technology of Advanced Materials, outlines advances and remaining challenges in developing potassium-ion batteries, which could deliver higher energy density than sodium-ion batteries and be especially suited for large-scale renewable energy storage. While lithium-ion batteries have driven the electronics and electric vehicle revolution, growing demand and limited lithium reserves are pushing researchers to seek alternatives.
“Potassium-ion batteries are emerging as a viable alternative due to the abundance and cost-effectiveness of potassium, but realising their potential requires the development of advanced anode materials tailored to the unique properties of potassium ions,” lead author Professor Eunho Lim told Asia Research News in early July. The review examines strengths and weaknesses of various anode materials, strategies to improve performance and stability, and the interplay between electrochemical parameters and physical structure in determining battery capacity and lifespan.
Lim plans to focus on designing cost-effective, high-performance, and safe anode materials, using advanced characterisation techniques to understand fundamental mechanisms. “Ultimately, my goal is to contribute to the commercialisation of potassium-ion batteries by developing materials that can rival or exceed the performance of current lithium-ion battery anodes,” he said.
