BCX电池的特点与反应特性

Some characteristics and reaction character of BCX cell

比较了BCX电池和Li/SOCl2电池的开路电压和放电性能,并用循环伏安曲线研究了这两种电池的阴极反应特性.结果显示:与Li/SOCl2电池相比,BCX电池的开路电压升高约300mV,放电初期,电池的放电电压提高了400～500mV.循环伏安曲线显示:Li/SOCl2电池在2.6 V出现了SOCl2还原峰,BCX电池在3.3 V和3.1 V分别出现了Cl2和Br2的还原峰,正极还原电位的提高使BCX电池的放电电压增高.

The open-circuit voltage and discharge performance of BCX and Li/SOCl2 cells were compared and their cathode reaction characteristics were studied by CV curves. The results showed that the open-circuit voltage of BCX cell increased about 300 mV and the discharge voltage increased about 400～500 mV during the initial discharge, eomparod with Li/SOCl2 cell. The CV curves exhibited that the Li/SOCl2 cell had a SOCl2 reduction peak at 2.6 V, the BCX cell showed two peaks of the reduction of Cl2 and Br2 at 3.3 V and 3.1 V. The increasing reduction potential of positive electrode could increase the discharge voltage of the BCX cell.
