novel nanomaterial to replace graphite in lithium-ion

Spiral: Development of nanostructured anode materials to

In the chapter on controlling material morphology, a thermal vapour method was proposed to synthesize novel structures by evaporating a low-boiling point metal out of a mixed-metal nanomaterial. Cobalt (Co) and zinc (Zn) differ in boiling point by ~2000 oC, hence Co/Zn mixed materials are feasibly tested for the proposed methodology.

News Story

Graphite (a form of pure carbon) is among the most superior options, and is also the most common in Li-ion batteries. When creating graphite anodes, lithium ions are easily electrochemically intercalated (embedded) into its layered structure, but for sodium ions it's a tight squeeze, and the result is a battery with sluggish performance and low capacity.
