"electrospinning nanofiber using guar gum, and sole solvent is water... oxidized functional groups regulate interactions with lithium ions... retained 93.3% capacity after 300 charge-discharge cycles... protective layer decomposes entirely within month in soil... suppresses dendrite growth, resulting in lithium metal anodes with unprecedented lifespan characteristics... water-based manufacturing method with biodegradable properties will significantly contribute to the commercialization of next-generation eco-friendly batteries"
