Long-term heat-storage materials based on λ-Ti3O5 for green transformation (GX)

Effective reuse of waste heat energy is an important energy savings issue for green transformation. In general, phase-change heat storage materials cannot store energy for a prolonged period. If a solid material could conserve the accumulated thermal energy and release it only on demand, then its heat-storage application potential is considerably widened. From this angle, in 2015, we proposed the concept of a long-term heat-storage material, in which latent heat is preserved until the material is triggered by an external stimulus. This feature article describes long-term heat-storage ceramics composed of lambda-trititanium-pentoxide (lambda-Ti3O5) from their discovery to heat-storage properties and future applications.

Automated summary

Effective reuse of waste heat energy is crucial for green transformation and energy saving. Traditional phase-change heat storage materials have limitations in storing energy for an extended period. However, the concept of long-term heat-storage materials, which can preserve thermal energy and release it on demand, opens up new possibilities. This feature article discusses the discovery, heat-storage properties, and potential applications of long-term heat-storage ceramics made of lambda-trititanium-pentoxide (lambda-Ti3O5).
