IMPROVEMENT OF DYNAMIC CHARACTERISTICS OF CURRENT COLLECTORS

S. M. Kolesov,M. V. Klymenko

To improve current collector dynamic characteristics, it is offered to use as basis graphite contact inserts whose side parts are coated by copper or aluminium. It leads to the reduction of the detachment factor and to the increase of current.
