Description

<p>The charge-discharge behaviour of tin-iron (13% by weight) alloy films plated on rolled copper foils was investigated. X-ray diffraction patterns of the tin-iron alloy films contained peaks corresponding to FeSn2 and tin. This negative electrode possessed a discharge capacity of 356 mAh/g after 50 cycles using metallic lithium as the counter electrode and was superior to tin-plated copper and carbon negative electrodes. These results suggest that the dispersion of iron in tin deposits separated from the tin-iron alloy during the first charge reaction improves the electrical conductivity between regions of tin-lithium intermetallic compounds formed during discharge and leads to the suppression of repeated contraction and expansion of the plated film.</p>
