A Si–MnOOH composite with superior lithium storage properties†
Abstract
The Si–MnOOH composite electrode exhibits very stable cycling and excellent rate capability, such as 1200 mA h g−1 at 12 A g−1, and 700 mA h g−1 at 20 A g−1. The γ-MnOOH component significantly promotes the alloying/de-alloying reaction between Si and lithium.
