- 摘要
- 相對於鋰離子電池(LiB)，全釩液流電池(VRFB)的電容量衰退嚴重，若是作為線上備援待 機(Hot Standby)儲放電模式，尚有循環泵等輔助電力耗能，相對自耗電更為嚴重。文獻所載175 kW/350 kWh電廠測試，熱待機電能耗漏率高達7.1%/hr，相當於每23分鐘就漏掉一戶人家一天的用 電量，無怪乎商用全釩液流電池通常運轉在持續充放電循環不停歇模式；即若如此，全釩液流電池 的產業應用，仍必須建立抑制電容量衰退的相關技術，如本文所整理的各專利。文內按著各專利發 明的時間序，記述技術進步的歷程，挈綱挈領概括主題專利的現貌，提供欲精研者的入門途徑。唯 盱衡綠能電網的未來儲能需求，至少10至100小時儲能容量，而且應包含待機備援模式，全釩液流 電池的後續研發方向，應規劃減少循環泵待機耗能與電解液穿膜漏電等相關配合作為。

- The capacity fading of vanadium flow battery (VRFB) is much worse than that of lithium ion battery (LiB), especially under the case of hot standby operating mode. The serious consuming rate under hot standby mode was reported to 7.1%/hr for the VRFB rating at 175 kW/350 kWh in the literature. This consuming rate is equivalent to the rate of one household's electricity consumption by every 23 minutes. It says why the demonstration of commercial VRFB’s would likely operate under continuous chargedischarge without stopping, scarcely under hot standby mode. Further improvement to alleviate the fading effect should be a crucial lesson for commercial VRFB’s widely application. Here described the lag behind in technology about capacity loss on VRFB. Comparing with lithium ion Battery, VRFB is a battery of much worse at both issues of self-discharge and capacity fading. Patents reviewed, by time sequence, described here briefly. It shows that industrial skills of solving them are blooming still. For the pronounce of future technology including 10 to 100 hours energy storage capacity duration with standby mode in the near future, the technologies about reducing energy loss on standby pump and separating electrolytes from the contact with membranes while in standby situation should be further developing.
