As an extended member of the thermoelectric family, ionic thermoelectrics (i‐TEs) exhibit
exceptional Seebeck coefficients and applicable power factors, and as a result have …

Heat is an abundant but often wasted source of energy. Thus, harvesting just a portion of this
tremendous amount of energy holds significant promise for a more sustainable society …

With the ever-growing development of multifunctional and miniature electronics, the
exploring of high-power microwatt-milliwatt self-charging technology is highly essential …

Thermoelectric materials are promising in relieving the energy crisis concerning harvesting
waste heat and providing a new environment-friendly self-power source for Internet of …

High-performance thermogalvanic cells have the potential to convert thermal energy into
electricity, but their effectiveness is limited by the low concentration difference of redox ions …

Low-grade heat (below 373 kelvin) is abundant and ubiquitous but is mostly wasted
because present recovery technologies are not cost-effective. The liquid-state thermocell …

Harvesting heat from the environment into electricity has the potential to power Internet-of-
things (IoT) sensors, freeing them from cables or batteries and thus making them especially …

Ionic thermocells have relatively high thermopowers based on the thermogalvanic effect, but
their small electricity output is still insufficient for practical applications. We demonstrated a …

Summary Low-grade heat (< 100° C) is abundant and ubiquitous but is generally discarded
owing to a lack of cost-effective recovery technologies. Emerging liquid-state thermocells …

More than half of the waste heat rejected into the environment has temperatures lower than
100° C, which accounts for nearly 85 PWh/year worldwide. Efficiently harvesting low-grade …
