Abstract

The invention provides filamentous organism-derived carbonaceous materials doped with organic and/or inorganic compounds, and methods of making the same. In certain embodiments, these carbonaceous materials are used as electrodes in solid state batteries and/or lithium-ion batteries. In another aspect, these carbonaceous materials are used as a catalyst, catalyst support, adsorbent, filter and/or other carbon-based material or adsorbent. In yet another aspect, the invention provides battery devices incorporating the carbonaceous electrode materials.
