摘要:
A high performance lithium-sulfur battery cell (10) includes the following features: (a) a negative electrode (14) including a metal or an ion of the metal; (b) a positive electrode (18) comprising an electronically conductive material; and (c) a liquid catholyte (16) including a solvent and a dissolved electrochemically active material comprising sulfur in the form of a sulfide of the negative electrode metal or a polysulfide of the metal. Such battery cells are characterized by an energy density, calculated based upon a laminate weight, of at least 400 Watt-hours/kilogram when discharged at a rate of at least 0.1 mA/cm 2 . Cells meeting these criteria often find use as primary cells.
摘要(中):
高性能锂硫电池(10)包括以下特征:(a)包含金属或金属离子的负极(14); (b)包括电子导电材料的正极(18); 和(c)包含溶剂和溶解的电化学活性材料的液体阴极电解液(16),其包含呈负极金属硫化物形式的硫或金属的多硫化物。 这样的电池单元的特征在于当以至少0.1mA / cm 2的速率放电时,基于叠层重量计算的能量密度为至少400瓦特/千克。 符合这些标准的细胞通常被用作主要细胞。
