Special Issue Information

Dear Colleagues,

Energy materials are particular materials that can participate in energy conversion or storage and provide the required energy, such as electrochemical materials, photovoltaic materials, and piezoelectric materials. Energy materials for sensors can convert light, thermal energy, mechanical energy, etc., in nature into electrical or other energy to produce signals and/or supply power for the sensing system.

The aim of this Special Issue is to present high-quality original research articles, methods, opinions, perspectives, and reviews on the frontiers of energy materials for sensor applications. Original contributions from both academia and industry are welcome. Topics may include, but are not limited to:

  • The design, synthesis, and characterization of energy materials for sensing applications, including piezoelectric materials, electrochemical materials, photovoltaic materials, etc.
  • Manufacturing techniques of sensors or sensing applications
  • Testing and application of sensors
  • Advanced sensing technologies

All-solid-state polymer lithium batteries have good safety, stability, and high energy densities and are employed in wireless sensors. However, the solid contact between the polymer electrolyte and the cathode leads to high interface resistance, limiting the broad application of solid-state lithium batteries. This paper proposes an ultrasonic fusion method to reduce the interface resistance between the polymer electrolyte and the cathode. The method applied a high-frequency ultrasonic vibration technique to impact the polymer electrolyte/cathode structure, melting the electrolyte at the interface and thus generating good contact at the interface. The experimental results showed that the ultrasonic fusion method decreased the interface resistance between the polymer electrolyte and the cathode by 96.2%. During the ultrasonic fusion process, high-frequency ultrasonic vibrations generated high temperatures at the interface, and the polymer electrolyte became molten, improving the contact between the electrolyte and the cathode. The ultrasonic fusion method eliminated the gaps at the interface, and the interface became more compact. Furthermore, ultrasonic vibrations made the molten electrolyte fill the holes in the cathode, and the contact area was enhanced, providing more Li+ ions transmission paths. Full article
