New Samsung silicon anode with graphene boosts volumetric capacity of LiCoO2 Li-ion cell 1.5x after 200 cycles...

The theoretical gravimetric capacity of silicon (Si) reaches almost 4,000 mAh g−1 . This unparalleled value has stimulated the battery community to invest considerable research efforts because the high gravimetric capacity enables one to increase the energy densities of lithium-ion batteries (LIBs) significantly, and thus bring future LIB applications, such as electrical vehicles, to a reality. In the past decade, diverse advanced electrode structures and binder designs were developed to resolve chronic capacity fading issues originating from the large volume change of Si, leading to substantially improved cycling performance even over thousands of cycles. In spite of the promising gravimetric value and substantial progress in cycle life, most of Si anodes demonstrated to date have focused primarily on the gravimetric capacity but have not offered a similar promise in thei...
