摘要： The subject invention discloses a novel method of providing a binary electrolyte-solvent solution in a solid battery system. A first component of this binary electrolyte solvent system is provided by a material which acts as a plasticizer in the formation of a solid polymeric matrix (separator), composite cathode and/or composite anode, and which also acts as an electrolyte solvent in the completed electrochemical cell. The second component of the binary electrolyte solvent system is an electrolyte solvent, which generally carries the electrolyte salt into the electrolytic cell precursor. The first and second components of the binary electrolyte solvent system mix within the electrolytic cell, dispersing the electrolyte salt throughout the binary electrolyte solvent system. The addition of the electrolyte salt to the electrolytic cell precursor acts to activate the cell precursor, and to form a functional electrolytic cell or battery system.

摘要： The methods and compositions of the invention provide two solutions to reduce the reactivity of VDF-based copolymers to lithiated graphite. The two approaches can be used separately or combined. In one embodiment, the relative proportion of the VdF and the other fluorinated monomer (OFM, i.e. HFP) in the copolymer is significantly reduced below conventional formulations in order to reduce the reactivity of the copolymer. In a second approach, the reactivity of the copolymer, over a broad range of monomer VdF:OFM molar ratios, is reduced by deactivating the reactive sites on the copolymer, thereby blocking the ability to undergo undesired reaction during cell operation. These methods and compositions have heretofore not been proposed and are of primary importance in preventing large exothermic reaction which can lead to thermal runaway when conventional polymer formulations are utilized in batteries in the presence of reactive components such as lithiated graphite.
摘要翻译：本发明的方法和组合物提供了两种降低VDF基共聚物与锂化石墨反应性的方法。这两种方法可以单独使用或组合使用。在一个实施方案中，为了降低共聚物的反应性，VdF和其它氟化单体（OFM，即HFP）在共聚物中的相对比例显着降低到低于常规配方。在第二种方法中，通过使共聚物上的反应性位点失活，共聚物在宽范围的单体VdF：OFM摩尔比下的反应性降低，从而阻止在电池操作过程中发生不希望的反应的能力。迄今为止尚未提出这些方法和组合物，并且在防止在诸如锂化石墨的反应性组分的存在下将常规聚合物制剂用于电池中时可导致热失控的大的放热反应是最重要的。

摘要： The invention provides a new family of compounds and a method of making the compounds. The new compounds are useful as ion conductive salts, and particularly useful as salts for batteries. The compounds of the invention are prepared from three principal reagents, bis (trifluoromethanesufonyl) methane (CF.sub.3 SO.sub.2).sub.2 CH.sub.2 ; benzoyl chloride; and pyridine which facilitates reaction and then is removed. A precursor sodium salt (CF.sub.3 SO.sub.2).sub.2 CHNa is first prepared. Then, equimolar amounts of the precursor sodium salt and pyridine are dissolved in anhydrous acetonitrile. A stoichiometric amount of the selected substitute benzoyl chloride is then added drop by drop. After addition of Li.sub.3 PO.sub.4, there is pyridine release and formation of the product of the aforesaid two reagents. In the benzene ring, R.sub.1, R.sub.2, R.sub.3, R.sub.4, and R.sub.5 are each identical or different and are each independently selected from hydrogen and an electron withdrawing substituent.
