A self-recovering current limiting fuse protecting a secondary battery
having a high rated voltage thanks to its improved breakdown voltage,
expanding the application range, shortening the charging time, and
realizing maintenance-free. The self-recovering current limiting fuse is
made by fluid-dispersing solid conductive particles into a liquid matrix
between electrodes. A current limiting operation through
evaporation/spreading of the solid conductive particles and a conducting
state brought about through collection of the solid conductive particles
between the electrodes by dielectrophoretic force of the solid conductive
particles are realized repeatedly, and a current limiting operation
through evaporation/spreading of the solid conductive particles by
overcurrent is realized.
