Enabling selective zinc-ion intercalation by a eutectic electrolyte for practical anodeless zinc batteries

Nature Communications, Journal Year: 2023, Volume and Issue: 14(1)

Published: May 27, 2023

Two major challenges hinder the advance of aqueous zinc metal batteries for sustainable stationary storage: (1) achieving predominant Zn-ion (de)intercalation at oxide cathode by suppressing adventitious proton co-intercalation and dissolution, (2) simultaneously overcoming Zn dendrite growth anode that triggers parasitic electrolyte reactions. Here, we reveal competition between Zn2+ vs intercalation chemistry a typical using ex-situ/operando techniques, alleviate side reactions developing cost-effective non-flammable hybrid eutectic electrolyte.

Incombustible Polymer Electrolyte Boosting Safety of Solid‐State Lithium Batteries: A Review

Advanced Functional Materials, Journal Year: 2023, Volume and Issue: 33(32)

Published: April 28, 2023

Abstract Lithium‐ion batteries with their portability, high energy density, and reusability are frequently used in today's world. Under extreme conditions, lithium‐ion leak, burn, even explode. Therefore, improving the safety of has become a focus attention. Researchers believe using solid electrolyte instead liquid one can solve lithium battery issue. Due to low price, good processability polymer electrolytes, increasing attention have been paid them. However, electrolytes also decompose burn under conditions. Moreover, dendrites formed continuously due uneven charge distribution on surface metal anode. A short circuit caused by dendrite cause thermal runaway. As result, solid‐state remains challenge. In this review, runaway mechanism is summarized, abuse test standard introduced. addition, recent works high‐safety solution strategies anode problems reviewed. Finally, development direction safe prospected.
