Research of MXenes and Their Applications in Sensors and Batteries

Abstract

MXene, a novel two-dimensional material class, demonstrates significant potential across diverse applications such as electrochemical heavy metal detection, pressure sensor active material, and sodium battery composites. MXene-based sensors, in the realm of heavy metal detection, exhibit high sensitivity and selectivity, which are vital in monitoring and controlling environmental pollution. These sensors utilize MXene's distinct conductive and surface properties, facilitating efficient and precise detection of heavy metals, including lead, mercury, and cadmium. In pressure sensors, MXene contributes to enhanced performance owing to its superior electrical conductivity and mechanical strength, allowing the creation of sensitive and robust sensors apt for cutting-edge applications in robotics, wearable technology, and IoT devices. Furthermore, MXene composites in sodium batteries lead to improved battery performance in energy storage. The high conductivity and electrochemical stability of MXene, coupled with its sodium ion hosting capability, render it an optimal material for boosting sodium battery capacity and cyclability. This progress holds immense importance in developing sustainable and efficient energy storage solutions. MXene's versatility and exceptional attributes continue to propel innovation in various fields, including environmental monitoring, energy storage, and sensor technology.
