The performance of CMC in a Co-based metal organic framework in lithium ion batteries

The Energy storage is a critical but weak link in the chain of sustainable energy applications. Developing high-capacity battery systems without sacrificing the safety, cost, power, and stability standards remains a formidable challenge, and requires optimized performance of every battery component. Besides other elemental parts in batteries, such as electrodes and the electrolyte, an efficient binder is critical to maintain both the electronic and mechanical integrity of battery electrodes.[1] The traditional binders, which interacts with electrode materials via weak Van der Waals forces and consequently lacks the necessary capabilities (e.g., the suppression of significant volume variations, the interface maintenance etc.), could not fulfill the high demands of batteries with high energy density.[2] Metal-organic frameworks (MOFs) are an emerging class of porous crystalline materials, prepared from self-assembly of metal ions and organic bridging ligands. Their highly ordered periodic porous structures give superior surface areas up to 7000 m2/g, which is not attainable by traditional porous materials. In addition, high thermal stability, tunable pore property, and various chemical reactive sites have attracted great attention from many different areas, including gas storage, chemical sensor, catalysis, proton conductor and LIBs.[3] Here we used Co-based MOF with CMC as binder in a half cell.
