SELF-RECOVERY CURRENT LIMITING FUSE USING DIELECTROPHORETIC FORCE

摘要

A self-recovering current limiting fuse protecting a secondary battery having a high rated voltage thaks to its improved breakdown voltage, expanding the application range, shortening the charging time, and realizing maintenance-free. The self-recovering current limiting fuse(1) is made by fluid-dispersing solid conductive particles(3) into a liquid matrix(2) between electrodes(4). A current limiting operation through evaporation/spreading of the solid conductive particles(3) and a conducting state brought about through collection of the solid conductive particles(3) between the electrodes (4) by dielectrophoretic force of the solid conductive particles(3) are realized repeatedly, and a current limiting operation through evaporation/spreading of the solid conductive particles(3) by overcurrent is realized.
