Abstract
En 中文
Since the electrolyte is critical to determine the performance and price of a Li-ion battery, a simplified yet effective system for optimizing commercial Li-ion battery is thus proposed by integrating a throttle mechanism (5 holes, 0.1 mm each) into the vacuum line, which significantly reduces the electrolyte loss from approximately 60 g to about 5 g per cell, representing a 5% saving in electrolyte usage, by well controlling its vapor flow. Furthermore, it avoids the formation of blackspots and lithium plating in anode. The implementation is estimated to yield annual cost savings of approximately USD 0.65 million per production line, alongside environmental benefits from the reduced electrolyte waste. The battery performance remains uncompromised, confirming the industrial viability of this strategy for cost-efficient and sustainable battery manufacturing
