在这项工作中，我们发现，与静态条件相比，在氩气中循环全电池可显着降低其容量衰减率，这是由于从电池中去除了气态反应产物。原位产生的气体的存在可以解释静态电池所测试的总容量衰减的很大一部分。为了了解循环过程中通常产生的特定气体种类的作用，基于 LiMn 2 O 4 和 LiCoO 2 的全电池在 Ar-H 2 、Ar-CO 、Ar-CO 2 和 Ar-CH 4 中进一步循环，反应气体成分在 0.5% 到 5% 之间，流速足够高以快速去除任何产生的气体。不同的电极对不同的气体敏感，气体成分的影响是非线性的，混合气体的影响不是相加的。尝试将容量衰减程度与通过二次离子质谱法测量的沉积在阳极上的过渡金属的量相关联，但没有发现强相关性。
In this work, it is found that cycling full cells in Ar, versus static conditions, significantly reduces their rate of capacity fade, which is attributed to the removal of gaseous reaction products from the cell. The presence of gases evolved in situ can account for a large fraction of the total capacity fade exhibited by the static cells tested. In attempt to understand the role of specific gaseous species commonly evolved during cycling, LiMn 2 O 4 and LiCoO 2 based full cells were further cycled in Ar-H 2, Ar-CO, Ar-CO 2, and Ar-CH 4 at reactive gas compositions between 0.5% and 5% and flow rates high enough to rapidly remove any evolved gas. The different electrodes were sensitive to different gases, the effects of gas composition were non-linear, and the effect of mixing gases was not additive. An attempt was made to correlate the degree of capacity fade with the amount of transition metal deposited on the anode, as measured by secondary ion mass spectrometry, but a strong correlation was not found.
