1results about How to "Increase peak current" patented technology

This invention discloses a lithium-carbon dioxide battery cathode, a lithium-carbon dioxide battery, and its preparation method, belonging to the field of battery technology. The invention utilizes the reaction of amino acids with inorganic acids to prepare amino acid salt ionic liquids. These amino acid salt ionic liquids are then used to pretreat sawdust, followed by carbonization to prepare activated carbon fibers. Finally, the prepared activated carbon fibers are used as the cathode catalyst to prepare the lithium-carbon dioxide battery cathode. The activated carbon fibers prepared by this method exhibit high peak current, large discharge capacity, and good cycle stability. The ionic liquid C8mimBF4 is used as both the CO2 capture and storage medium and the electrolyte, improving battery life and effectively ensuring battery safety and environmental friendliness. This invention employs multi-cell packs and semi-dry electrode processes to construct a manufacturing process for lithium-carbon dioxide batteries. The resulting batteries exhibit high energy density and good operational stability, demonstrating excellent economic prospects and practical value.
