Next-gen lithium-metal batteries for electric vehicles, smart grids

Next-gen lithium-metal batteries for electric vehicles, smart grids | Accumulators, capacitors, and energy storage systems | Scoop.it
Electric vehicles, wind turbines or smart grids require batteries with far greater energy capacity than currently available. A leading contender is the lithium-metal battery. However, dendrite, or sharp needles, made of clumps of lithium atoms can cause the batteries to heat up, lose efficiency and occasionally short-circuit. Using supercomputers, researchers have simulated the behavior of graphene oxide nanosheets that can limit the formation of dendrites.

Promising electrolyte structure designs for solid-state lithium-ion batteries

Promising electrolyte structure designs for solid-state lithium-ion batteries | Accumulators, capacitors, and energy storage systems | Scoop.it
Finding low-cost solid materials capable of efficiently and safely replacing liquid electrolytes in lithium-ion batteries has been a considerable research interest over the past years. Of the various types of solid electrolytes that have been developed so far, composite polymer electrolytes exhibit acceptable Li-ion conductivity due to the interaction between nanofillers and polymer. By fabricating a pre-percolated network of ceramic filler instead of distributing particles in polymer, a 3D interconnected ceramic framework provides continuous pathways for ion conduction. This novel method will help to develop composite materials in a different but much improved way than conventional particle distributions.
