Abstract

<abstract abstract-type="graphical" xml:lang="en" id="aenm201401742-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>A planar microbattery that enables various in situ measurements of lithiation of 2D materials on the individual‐flake scale</bold> is developed. A large conductivity increase of thick MoS₂ crystallite lithiation due to the formation of a percolative Mo nanoparticle network embedded in a Li₂S matrix is observed. The nanoscale study leads to the development of a novel charging strategy for batteries that largely improves the capacity and cycling performance confirmed in bulk MoS₂/Li coin cells. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgj5jh9mpp" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
