Antisolvent engineering enhanced high-entropy liquid flow thermocells with giant power densities for low-grade heat harvesting

A cost-effective and facile strategy for enhancing solvation entropy increase of redox ions is proposed through antisolvent engineering, which reaches a giant P max /Δ T 2 of 64.5 mW m −2 K −2 and η r of 11.8% with low cost and low temperature resistance.
