Abstract: A binder for a lithium-sulfur electrode is proposed. The binder can improve the capacity and lifespan characteristics of a lithium-sulfur secondary battery by suppressing the shuttle reaction due to the elution of polysulfide through the interaction of lithium polysulfide while maintaining the binding characteristics of the binder. This binder may be used for a positive electrode and a lithium-sulfur secondary battery. The binder may include a modified polyvinylidene fluoride (PVdF)-based binder that is soluble in an organic solvent. The modified PVdF-based binder may include a PVdF-based main chain and a functional group having a carboxylic group or carbonyl group grafted as a side chain.

Abstract: A system, computer readable medium, apparatus and/or method for magnetic resonance imaging (MRI) reconstruction that mitigates local blurring caused by static off-resonance and concomitant fields. The MRI reconstruction system may use phantom-based gradient impulse response function (GIRF) measurements and analytic expressions to predict the concomitant fields. GIRFs capture gradient delays, eddy current effects, and mechanically induced field oscillations. For each gradient axis, a MR system is perturbed with a set of input gradients. Gradients predicted with phantom-based GIRFs can better estimate concomitant fields than nominal gradients. A novel image reconstruction method incorporates higher-order Maxwell fields and GIRF trajectory corrections and may be treated as “invisible” field probes that require no special hardware but GIRFs measured with phantom-based methods and an analytic model of concomitant fields that depends on coil geometry and severity of gradient non-linearity.
