评价了由双氟磺酰亚胺锂(LiSFI)1：1体积比的碳酸乙烯和碳酸二甲酯组成的液体电解液在锂离子电池中的性能。酰亚胺盐具有热稳定性高的优点，可以提供一种比LiPF6更安全的替代品，因为LiPF6容易形成HF。然而，研究最多的锂亚胺盐双(三氟甲磺酰基)亚胺锂存在着铝的腐蚀问题，而铝通常被用作阴极集电体。在此基础上，研究了双氟磺酰亚胺锂液体电解液的腐蚀性能。皇冠版权所有(C)2008由爱思唯尔出版。保留所有权利。
The performance of a liquid electrolyte composed of lithium bis-fluorosulfonyl imide (LiSFI) in a 1: 1 volume of ethylene carbonate and dimethyl carbonate is evaluated for use in lithium ion batteries. Imide salts offer the benefits of higher thermal stability and could provide a safer alternative to LiPF6 which is prone to the formation of HF. However, the most studied lithium imide salt, lithium bis(trifluoromethanesulfonyl) imide, is well known to have a problem with corrosion of aluminum which is commonly used as the cathode current collector. Consequently, the corrosion properties of liquid electrolytes based on lithium bis-fluorosulfonyl imide are also investigated. Crown Copyright (C) 2008 Published by Elsevier B.V. All rights reserved.
