The Shanghai Institute of Ceramics has made significant progress in the research on flexible organic/inorganic thermoelectric composites.

Flexible thermoelectric energy conversion technology can convert temperature differences in the environment or on the human body into electrical energy, enabling self-powered electronic devices and holding great potential for applications in fields such as wearable electronics. Traditional inorganic thermoelectric materials exhibit excellent thermoelectric performance but lack flexibility; while organic thermoelectric materials, though possessing good flexibility and bendability, have extremely low thermoelectric performance.

The Shanghai Institute of Ceramics has opened up a new research direction in inorganic flexible thermoelectric materials.

Flexible thermoelectric energy conversion technology can transform ubiquitous temperature differences in the environment into electrical power output, holding great promise for applications in fields such as flexible electronics. However, current high-performance inorganic thermoelectric materials are all brittle and lack flexibility. While miniaturizing these materials and integrating them onto flexible substrates can provide a certain degree of bendability, they remain highly susceptible to fracture under significant bending or large deformations. On the other hand, although organic thermoelectric materials exhibit excellent flexibility and bendability, their charge carrier mobility is significantly lower than that of inorganic materials, making it difficult to achieve efficient energy conversion and power output.

The Shanghai Institute of Ceramics has achieved significant innovative progress in device research on liquid-like thermoelectric materials.

Advanced thermoelectric conversion technologies hold broad application prospects in fields such as semiconductor cooling, industrial waste heat recovery, and power generation from exhaust heat of automobile engines. For a long time, research on thermoelectric materials has primarily focused on crystalline compounds. In 2012, the thermoelectric team at the Shanghai Institute of Ceramics, Chinese Academy of Sciences, discovered a new class of high-performance, quasi-liquid thermoelectric materials with "phonon liquid–electron crystal" characteristics by introducing ions with "quasi-liquid-like" properties into solid-state materials to weaken or even eliminate certain transverse acoustic phonon modes (Nat. Mater. 2012). The thermoelectric team at the Shanghai Institute of Ceramics further studied and elucidated the mechanisms underlying the migration and precipitation of mobile ions in quasi-liquid materials under external field effects, and proposed a thermodynamic criterion for determining whether a material can be used stably (Nat. Commun. 2018).

The Shanghai Institute of Ceramics has achieved significant innovative progress in the study of thermal conductivity of materials during phase transition.

Thermal conductivity is one of the fundamental physical properties of materials and plays an important, even decisive, role in many fields. Materials with high thermal conductivity are widely used in heat dissipation applications, whereas materials with low thermal conductivity are primarily employed in thermal insulation. The definition and measurement of thermal conductivity both require adiabatic conditions—no energy exchange between the material and its surroundings, meaning that heat can only be conducted from higher to lower temperatures within the material itself.

The Shanghai Institute of Ceramics has achieved significant innovative progress in the study of service stability of quasi-liquid thermoelectric materials.

Recently, Associate Researcher Qiu Pengfei, Researcher Shi Xun, and Researcher Chen Lidong from the Shanghai Institute of Ceramics, Chinese Academy of Sciences, in collaboration with Professor G. Jeffrey Snyder from Northwestern University in the U.S. and Professor Jürgen Janek from Justus Liebig University Giessen in Germany, conducted an in-depth analysis of the migration and precipitation mechanisms of mobile ions in quasi-liquid thermoelectric materials under external field effects. Combining theoretical and experimental approaches, they proposed a thermodynamic stability criterion for determining whether "quasi-liquid" ions can precipitate out of the material, and also provided corresponding experimental characterization methods and techniques.

The Shanghai Institute of Ceramics has made significant progress in the field of organic-inorganic composite thermoelectric materials.

Organic-inorganic composite thermoelectric materials not only possess the advantages of organic materials—such as light weight, high ductility, low cost, and ease of preparation—but also can achieve superior thermoelectric performance compared to pure organic materials. As a result, they have continuously attracted significant attention in recent years. However, conventional organic/inorganic composite thermoelectric materials prepared by in-situ polymerization or mechanical blending suffer from several issues: inorganic nanoparticles are difficult to disperse, prone to oxidation, hard to control in terms of particle size, and often require an excessive amount of inorganic phase (typically >25 wt%). These problems undermine the actual composite effect and severely hinder the advancement of organic/inorganic composite thermoelectric materials.
