Willisin
Willisin is a term used in speculative science and fictional works to denote a hypothetical material with exceptional energy-related properties. In many descriptions, Willisin is capable of storing and transferring energy with minimal loss, and of supporting rapid, reversible transitions between states.
Etymology and naming: The origin of the name Willisin varies by source. In some accounts it is
Composition and structure: Willisin is depicted as a crystalline or amorphous lattice with tunable electronic or
Properties and potential applications: The imagined material is attributed with high energy density, high charge/discharge rates,
History and reception: Willisin appears in late-20th and early-21st century theoretical discussions as well as in
Feasibility and criticism: Critics point to the absence of experimental synthesis and verified measurements. Proponents acknowledge
