“…These tailored structures with molecule-level integrations make the active materials fully display their potential with more improved performance as a consequence, but the clear elucidation of the influence of interface heterostructures is absent. The graphene-based materials also show their advantages in constructing freestanding and flexible electrodes, , such as using rGO film as host to fabricate ultrathin and robust free-standing Li composite film . Overall, graphene and the composites as electrodes can enable large-capacity, high-rate, and long-term cycling stability performance at the same time in the three systems.…”

“…Advanced rechargeable batteries are currently being developed to power a variety of appliances, ranging from portable devices like smartphones to large-scale equipment including electric vehicles and grid energy-storage systems [1][2][3][4][5]. A large number of studies have focused on the development of high-capacity composite electrodes to enhance the energy density and performance of the next-generation rechargeable batteries [6,7]. In particular, silicon (Si) is theoretically expected to provide about ten times higher capacity (ca.…”

“…A few strategies have been proposed to inhibit the Li/Na dendrites, such as anchoring lithiophilic/sodiophilic sites on the current collector, regulating the Li/Na-ion distribution, and modifying the solid–electrolyte interface (SEI) layer. Although the performance of Li/Na anodes is improved by the above strategies, these improvements are usually reflected by the thick Li/Na foils in most previous studies, and the achieved effect is not satisfied with the thin Li/Na anodes. Thick Li/Na anodes mean a low utilization of Li/Na metal and a low depth of discharge (DOD), which significantly reduces the energy densities of lithium/sodium metal batteries (LMBs/SMBs) . It also severely weakened the competitiveness of commercial lithium-ion batteries.…”
