Ultrafast and Sustainable Lithium Ion Batteries

Organic composite electrode materials have been prepared by a facile in-situ chemical polymerization method. The common structure possessed in both electroactive material and electron conductive material allows intimate contacts, resulting in conductive polymeric composites with highly reversible redox reactions and good structure stability. It has been demonstrated that the composite material has the optimal combination of good electronic conductivity and fast lithium reaction kinetics. The synergistic effect between the materials enables a high reversible capacity of 216.8 mA h g-1 at a current rate of C/10, as well as a high-rate cycling stability, that is, a high capacity of 89.6 mA h g-1 at a high current rate of 20 C with a capacity retention of 94 % after 1000 cycles. The elaborate combination of high electronic conductivity of the coating and fabulous redox reaction reversibility of the matrix offers an economic way to prepare high performance lithium ion batteries for sustainable energy storage applications. This composite material can also be used as electrode materials for wearable fabric to monitor the biometric information.
