Carbon-modified Na2Ti3O7·2H2O nanobelts as redox active materials for high-performance supercapacitor

The C/Na-TNBs supercapacitor has been encapsulated by the flexible and stretching PDMS, which has flexible property. The maximum storage performance can be obtained by mixing an optimal amount of C into Na2Ti3O7·2H2O. Unique layered structure further verifies the charging and discharging mechanism systematically.251
