摘要：
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. A secondary electrochemical cell wherein the length and width of the negative electrode extend beyond the length and width of the positive electrode to provide the positive electrode bounded by the negative electrode.
