摘要： Nanostructured gel polymer electrolytes that have both high ionic conductivity and high mechanical strength are disclosed. The electrolytes have at least two domains—one domain contains an ionically-conductive gel polymer and the other domain contains a rigid polymer that provides structure for the electrolyte. The domains are formed by block copolymers. The first block provides a polymer matrix that may or may not be conductive on by itself, but that can soak up a liquid electrolyte, thereby making a gel. An exemplary nanostructured gel polymer electrolyte has an ionic conductivity of at least 1×10−4 S cm−1 at 25° C.

摘要： An electrode assembly that includes an electrode film and a current collector is provided. The electrode film includes electrode active material, electronically conductive particles, and a solid polymer electrolyte. In some embodiments, no additional binder is used as the solid polymer electrolyte also acts as a binder to hold together the active material and electronically conductive particles, thus creating a freestanding electrode film. Such a freestanding film makes it possible to deposit a very thin current collector layer, thus increasing specific energy and specific power for electrochemical cells in which these electrode assemblies are used.

摘要： A polymer that combines high ionic conductivity with the structural properties required for Li electrode stability is useful as a solid phase electrolyte for high energy density, high cycle life batteries that do not suffer from failures due to side reactions and dendrite growth on the Li electrodes, and other potential applications. The polymer electrolyte includes a linear block copolymer having a conductive linear polymer block with a molecular weight of at least 5000 Daltons, a structural linear polymer block with an elastic modulus in excess of 1×107 Pa and an ionic conductivity of at least 1×10−5 Scm−1. The electrolyte is made under dry conditions to achieve the noted characteristics. In another aspect, the electrolyte exhibits a conductivity drop when the temperature of electrolyte increases over a threshold temperature, thereby providing a shutoff mechanism for preventing thermal runaway in lithium battery cells.

摘要： It has long been recognized that replacing the Li intercalated graphitic anode with a lithium foil can dramatically improve energy density due to the dramatically higher capacity of metallic lithium. However, lithium foil is not electrochemically stable in the presence of typical lithium ion battery electrolytes and thus a simple replacement of graphitic anodes with lithium foils is not possible. It was found that diblock or triblock polymers that provide both ionic conduction and structural support can be used as a stable passivating layer on a lithium foil. This passivation scheme results in improved manufacture processing for batteries that use Li electrodes and in improved safety for lithium batteries during use.
摘要翻译： 长期以来，已经认识到用锂箔替代Li插层石墨阳极可以显着提高能量密度，这是由于金属锂的容量显着提高。 然而，在典型的锂离子电池电解质的存在下，锂箔不是电化学稳定的，因此用锂箔简单地代替石墨阳极是不可能的。 发现提供离子传导和结构支持的二嵌段或三嵌段聚合物可以用作锂箔上的稳定的钝化层。 这种钝化方案导致改进了使用锂电极的电池的制造处理，并且在使用期间改善了锂电池的安全性。
