Abstract
A rechargeable alkali metal electrochemical cell, and preferably a lithium-ion secondary cell, constructed of low magnetic susceptibility materials, is described. The non-magnetic characteristics enable the secondary cell to be used within the confines of a Magnetic Resonance Imaging system. The cell includes an electrolyte solution comprising ethylene carbonate, dimethyl carbonate, ethylmethyl carbonate and diethyl carbonate.
