A PROXYL‐Type Norbornene Polymer for High‐Voltage Cathodes in Lithium Batteries

“…Organic redox-active polymers are macromolecules displaying reversible electrochemical reactions, and recently attracting attention as components of rechargeable electrodes for nextgeneration batteries. [1][2][3][4] The polymers often exhibit much higher outputs than traditional inorganic electrodes, such as lithium metal oxides. [1,2] The typical charge/discharge rates for the polymers are more than 10 C (x C corresponds to a rate for full charge or discharge in 1/x hours), while the inorganics normally offer less than 1 C. [1][2][3]5,6] The intimate interfaces in the electrodes, consisting of active materials, conductive carbons, and binders, can be more easily formed by the polymers, to realize quick charge propagation.…”

Development of Waste Polystyrene-Based Copper Oxide/Reduced Graphene Oxide Composites and Their Mechanical, Electrical and Thermal Properties

“…Literature studies exhibit that such substandard characteristics of polymers can be upgraded by incorporating a variety of fillers into the polymer matrix [ 22 ]. Electrical conductivity is a highly desirable property of polymeric composites, based on which they are incorporated into gas sensing materials [ 23 ], electronic devices [ 24 ], energy storage [ 25 ], electrochemical tools [ 26 ], photovoltaic cells [ 27 ], fuel cells [ 23 ], transistors [ 24 ], electromagnetic shielding films [ 28 ] and optoelectronic devices [ 29 ].…”

Leakage-Free Nucleic Acid Biochip Featuring Bioinert Photocurable Inhibitor

“…We developed a novel technique for permanently attaching PCB to PDMS to address this issue, thereby preventing microfluidic spillage from the sensor. The new bonding is not only biologically [37][38][39] and electrochemically [40][41][42] inert but also exhibits good mechanical properties. This article discusses the fabrication techniques for this biochip as well as its performance.…”
