Descriptif des activités de rechercheHigh energy density of binder free sintered electrodes were prepared by Spark Plasma Sintering(SPS) technique.LiFePO4 and Li4Ti5O12 sintered electrodes are made with higher specific capacity compared to conventional lithium ion batteries. A full battery having LFP positive and LTO negative electrodes were assembled and working with superior electrochemical performances. Pore forming agents were used with active materials to promote better lithium ion diffusion and charge transfer inside the electrodes during cell operation. The main idea is to reduce the weight of non-active materials present in batteries like binder, current collector, lid, hence by improving the gravimetric and volumetric energy density of lithium ion batteries.
