Capacitor batteries utilizing a dual-energy storage mechanism demonstrate enhanced energy and power densities. These typically incorporate hybrid electrodes, formed by combining cathode materials with nanocarbon or other supercapacitor materials. However, the capacitance–cooperative effect of nanocarbons remain complex due to intricate surface interfacial interactions between electrode electrolyte, particularly in cathodes operating at high voltages, which accelerate decomposition...
TiNb2O7 (TNO) is a high-specific-capacity intercalation-type anodic material with excellent cycle performance and appropriate working potential (∼1.6 V vs Li+/Li). However, its low electronic conductivity lithium-ion diffusion coefficient can lead to poor kinetics, which has become bottleneck that needs be urgently addressed for the further development of TiNb2O7. Herein, unique MXene encapsulating TNO particles (TNO@MXene) was fabricated through simple electrostatic self-assembly process....
Intercalation-type metal oxides are promising active anode materials for the fabrication of safer rechargeable lithium-ion batteries, as they capable minimizing or even eliminating Li plating at low voltages. Due to excellent cycle performance, high specific capacity and appropriate working potential, TiNb2O7 (TNO) is considered be candidate materials. Despite a lot beneficial characteristics, slow electrochemical kinetics TNO-based anodes limits their wide use. In this paper, TiNb2O7@C was...
