BEIJING (SCMP): Chinese scientists have found fibre from the konjac plant – an ingredient in noodles and jelly added to hotpot – can improve the performance of water-based zinc batteries in low temperatures by keeping their components from freezing.
Aqueous zinc-ion batteries, still largely in development, are a promising alternative to lithium batteries because of their high theoretical capacity, superior safety, and the wider availability of zinc compared with lithium.
