摘要
By using nanometer-sized RuO2 to "metalize" tiny pores and even "repair" incomplete electronically conducting (carbon) networks in porous carbon-containing LiFePO4 (see figure), the kinetics and rate capability of the composite are significantly improved. The key lies in the bonding properties of RuO2, which enables good contact to both the oxidic storage material as well as the carbon structures used as current collector.
