Pure lithium offers an impressive energy density compared to graphite or silicon-based materials. However, this potential is hindered by challenges such as dendrite formation—which can lead to short circuits—and negative interactions with existing electrolyte solutions, causing cell swelling and early failures. Researchers across the globe have dedicated their efforts to solving these significant obstacles in the development of lithium-metal anodes.
The Breakthrough from KAIST
Recently, a team from the Korean Advanced Institute of Science and Technology (KAIST) announced a remarkable advancement that they claim can increase the lifespan of lithium-metal anodes by a staggering 750%. While this is a bold assertion, their innovative approach deserves a closer look.
