“…Conductivity Results. In electrolyte solutions based on a salt dissolved in a liquid (e.g., LiBETI) in EC, PC, EMC and their mixtures), cations and anions are solvated (coordinated to) solvent molecules; e.g., the solvation number of Li + in PC is probably 3−4, and for the anion, the solvation number is probably 1 (e.g., see ref ). When the conductivities for these solutions are studied, it is the mobility of the whole complex (ion + the solvent coordination sphere) that moves under the applied electric field.…”

Conductivity and transport properties have been determined for gelled polymer electrolytes of three compositions: a base PVdF-polymer gel with organic carbonate solvents as plasticizers and LiN(SO(2)C(2)F(5))(2) electrolyte, a second polymer electrolyte with 5 mass % 1-ethyl-3-methylimidazolium bisperfluoroethylsulfonyl imide (EMI-BETI) added to the base polymer electrolyte, and a third PVdF polymer electrolyte using only EMI-BETI as the plasticizer. Conductivities were studied over the temperature range +25 to -40 degrees C, and for all three gels, the temperature dependence of the conductivities was found to follow the VTF equation, which is consistent with the free volume model for ion transport. For the gel containing 5 mass % EMI-BETI, transport numbers were determined from +50 to -20 degrees C and were found to decrease as the temperature decreased. Although there are no theoretical models to treat and interpret the temperature dependence of transport numbers, we found that a modified VTF equation resulted in an excellent fit to the temperature dependence of the transport number, which is another confirmation of a free volume model for transport in these gelled polymer electrolytes.

“…It is difficult for a single solvent system to display both a high dielectric constant and a low viscosity (Table 21 [269][270][271]); therefore, many researchers have explored mixtures of solvents [263,264,266,272] to develop an advanced liquid electrolyte for Liion batteries. The following equation represents a binary solvent system [264]: where m is the amount of Li salt in molality (mol kg −1 ) and w is the weight fraction.…”

“…Researchers have described the decomposition of lithium-based cell electrolytes beginning at 80-85 C and possible volatility, which produces cell ''puffing''. 49 The solid electrolyte interface (SEI) on the lithiated carbon electrode (anode) can start to breakdown at these temperature levels allowing continuous reactions to occur that affect cell capacity. On the cathode, the SEI can grow in thickness, which increases the internal impedance and degrades the power delivery capability.…”

Multifunctional structure-battery composites were developed using fiber reinforced marine composites for structure function and rechargeable lithium-ion cells for energy storage and structure function. Laminate, sandwich, and modular beam configurations were fabricated and tested to determine flexural stiffness and strength, energy storage capacity versus discharge rate, and buoyancy (density). The structure-battery composites exhibited higher flexural stiffness but lower strength than equivalent unifunctional designs, energy storage capacities between 40 and 60 Wh/L, and buoyancies bracketing the unifunctional specimen values. Issues requiring further attention include: improved bending strength, simplified fabrication, reversible attachments for modular components, electrical wiring and connections, and battery management circuitry.
