    摘要: Lithium-ion electrochemical cells are provided that include a positive electrode that includes a lithium metal oxide or a lithium metal phosphate, a negative electrode capable of intercalating or alloying with lithium, and an electrolyte that includes an additive. The additive includes a multifunctional anion that has the formula, X—SO2—Rf′—SO2—Y, wherein X and Y are, independently, either O— or RfSO2N—, Rf is a straight or branched fluoroalkyl moiety having from 1 to 6 carbon atoms, and can, optionally, contain one or more in-chain heteroatoms, wherein Rf′ is a straight or branched chain or cyclic fluoroalkylene having from 1 to 10 carbon atoms and can, optionally, contain one or more in-chain heteroatoms, and wherein both Rf and Rf′ have a maximum of 20% non-fluorine substituents. The provided additives can improve the performance, hydrolytic stability, and thermal stability of the provided electrochemical cells.

    摘要: A lithium ion battery pack charging system comprises a lithium ion battery pack having positive and negative terminals and comprising a plurality of lithium ion cells connected in series and in electrical communication with the positive and negative terminals. Each of the plurality of lithium ion cells comprises an anode, a cathode, and electrolyte composition comprising a redox shuttle and a lithium salt at least partially dissolved in solvent. A charger in electrical communication with the positive and negative terminals is capable of charging the lithium ion battery pack at a first charge rate and a second lesser charge rate. The system further comprises a charger controller capable of monitoring input data and switching the charger from the first rate to the second changes based on the input data. A device comprising the lithium ion battery pack charging system is also disclosed.
