Abstract: Provided herein are positive electrodes for lithium batteries, particularly lithium sulfur batteries, and the manufacture thereof. Particularly, such electrodes have good performance characteristics, such as capacity and capacity retention, even at very high loading of sulfur (e.g., >5 mg/cm2), as well as flexibility. Exemplary manufacturing techniques include the electrospraying of sulfur (e.g., electrode active sulfur compounds), and an optional additive (e.g., a nanostructured conductive additive), onto a porous, conductive substrate (e.g., a porous carbon substrate, such as comprising multiple layers and/or domains).
