dc.description.abstract | 電池的儲存對電池老化的影響對於電池壽命的預估相當重要,目前已有許多學者研究電池電容量在儲存過程中會損失,然而只有極少數的人探討儲存過後之電池循環壽命與電池儲存時間的影響為何。因此本研究將探討電池儲存條件與循環壽命之關係,以及老化的相關機制為何,並討論電池循環過程中之鋰金屬沉積行為。
本研究透過針對不同儲存時間及儲存溫度下的電池進行循環老化實驗,並透過ICA法探討老化機制。從實驗結果中可以得知NMC電池儲存時間越長,循環老化壽命越短,且將電池儲存於低溫環境中,能有效減緩電池循環老化壽命縮短的現象。透過ICA方法觀察dQdV圖峰值變化,並從峰值變化發現NMC電池循環老化過程之老化機制為可用鋰損失、活性材料負極脫鋰損失以及活性材料正極脫鋰損失,且儲存過後電池之老化機制,可用鋰損失以及活性材料正極脫鋰損失會加速,然而儲存於低溫狀態下的電池可以減緩加速損失的發生。本研究透過實驗結果找出實驗所使用之NMC電池在室溫下進行全充全放的循環實驗,電池老化前中期與老化後期之分界為何,並成功透過半經驗公式描述NMC電池經過不同儲存條件下的循環老化壽命為何。 透過鋰金屬沉積模型,假設負極由於製程上的誤差會有不規則之凸起,可以從模型中發現,鋰金屬電池在一次充放電循環後,會有鋰金屬沉積於不規則凸起之尖端。造成此現象之原因為負極表面不規則的幾何形狀,導致電解液電場分布不均勻且充電過程中電解液電流匯集於不規則凸起尖端。 | zh_TW |
dc.description.abstract | The impact of battery storage on battery aging is very important for battery cycle life estimation. At present, many scholars have studied that battery capacity will be lost during storage. However, only a few people discuss the battery cycle life after storage. Therefore, this study will explore the relationship between battery storage conditions and cycle life, the relevant mechanisms of aging, and discuss the lithium metal deposition behavior during battery cycling.
This study conducted a cyclic aging experiment on batteries for different storage time and storage temperatures. In the study, the aging mechanism was explored through the ICA method. It can be known from the experimental results that the longer the calendar of the NMC battery, the shorter the cycle life. When the battery is stored in a low-temperature environment, it can effectively slow down the cycle aging of the battery. According to the peak evolution of the dQdV pattern obtained from the experiment, the aging mechanism of the NMC battery cycle aging was LLI, LAMdePE and LAMdeNE. After the battery calendar, the LLI and LAMdePE mechanisms will become more apparent during battery cyclic aging. However, batteries stored in a low-temperature circumstance can alleviate the occurrence of aging mechanisms. Based on the experimental results, this study finds out the non-linear aging starting position of the NMC battery used in the experiment. The semi-empirical formula was successfully used to describe the cycle life of NMC batteries under different storage conditions. According to the lithium metal deposition model, it is assumed that the negative electrode has irregular protrusions due to errors in the process. It can be found from the model that after a charge and discharge cycle of the lithium metal battery, lithium metal is deposited on the tip of the irregular protrusion. The cause of this phenomenon is an irregular geometry of the negative electrode surface, resulting in uneven distribution of the electrolyte electric field and the accumulation of electrolyte currents at the irregular raised tip during charging. | en |
