Lithium metal batteries (LMBs) can provide nearly 10 times higher energy density compared to the present Lithium-ion batteries (LIBs) and hence are identified as one of the potential future storage systems. However, LMBs pose certain safety concerns and cannot be used for fast-charging applications. Uncontrolled dendrite formation, leading to excessive heating and battery short circuit is one of the critical challenges of its advancement.
Researchers have previously attempted to address the safety concerns in LMBs but with methods that were laboursome and money/time intensive. T. N. Narayanan’s lab at the Tata Institute of Fundamental Research, Hyderabad (TIFRH) reports a simple, scalable, cost-effective method to assemble a safer and durable lithium metal battery.
A porous separator membrane lies between the electrodes in a battery, keeping them apart, and is crucial to prevent a short circuit. When a battery is used for some time,…
