Abstract
Further described herein are extensions to the basic concept of LHs as electrode materials, include both new materials for use with LHs and higher order poly-layer hydroxides (PLHs) as well as methods for synthesizing improved LH material such as with conductive supports or through the use of cross-linking. Finally, also described herein are embodiments enabling the use of LHs as flow electrodes as well as the use of 2-d LH materials for surface redox reactions.
