Improved battery performance is vital for high-power uses, but traditional electrode production methods can be complex, expensive, and harmful to the environment.
This study presents a new, eco-friendly microneedle technique inspired by acupuncture, utilizing cosmetic microneedle molds to create holes in lithium iron phosphate electrodes, which enhances electrolyte flow and ion transport.
Findings indicate that these microneedle-treated electrodes outperform standard electrodes in terms of rate performance and capacity, suggesting a potential for scaling up production for better battery technology.
