Popis: | The electrochemical performance of lithium-ion batteries (LIBs) could be improved using a two-layered cathode produced by a simultaneous slot-die coating method. The composition in each layer contained different proportions of two conductive additives; one with a high percentage of micro-sized graphite, and the other with a high percentage of nano-sized carbon black. Of the four cell structures fabricated, the two-layered cathode with an upper layer having more carbon black and a lower layer having more graphite particles was found to give the best current discharge capacity and longer life cycle. This finding could have potential applications in new LIBs design. |
