This work presents the first application of three-dimensional digital image correlation for real-time displacement and strain analysis of a pouch type lithium-ion battery. During the electrochemical charge-discharge processes, displacements in the x-, y-and z-directions vary at different states-of-charge (SOCs) attributed to the expansion and the contraction of the interior structure. The z-displacement is observed to develop and concentrate at the vicinity of the openings of the jelly-roll structure. By resolving the displacement components, the progression and distribution of the surface strains, including principal and von-Mises strains, are computed in the charge-discharge processes. It is shown that the dominant strains are up to 0.12 % in the rolling direction of the jelly-roll structure and distribute uniformly on the x-y plane over the surface.

“…These two particle populations are suspended and mixed sequentially in propylene carbonate (PC) with 1M of lithium bis(trifluoromethane)sulfonamide (LiTFSI). It is well known that colloidal particles will rapidly aggregate when suspended in polar solvents under high ionic strength conditions due to van der Waals interactions.[20] Hence, we first introduce a non-ionic dispersant, polyvinylpyrrolidone (PVP), with appropriate amount to selectively stabilize the LFP particles fully, but not the KB particles.[ [21][22][23] PVP has been shown to sterically stabilize colloidal particles in both aqueous [22][23][24] and non-aqueous [25] media leading to well dispersed suspensions. PVP is especially useful for SSFC electrodes, as it confers stability even in systems with high (1 M) salt concentrations that undergo electrochemical charging and discharging.…”

“…PVP is especially useful for SSFC electrodes, as it confers stability even in systems with high (1 M) salt concentrations that undergo electrochemical charging and discharging. We chose LFP due to its low volume expansion (ε linear ∼ 2.2%) [24] when charged or discharged.We then added Ketjenblack EC-600JD (KB) particles to the suspension, which form a conductive network at a low percolation threshold. [25] We investigated the effects of biphasic suspension composition on the microstructure, flow behavior, and electrochemical performance of these SSFC electrodes.…”

The rapidly increasing deployment of wind and solar energy has resulted in an urgent need for a smarter, more efficient and reliable electronic grid for load balancing. [1,2] Currently, only a small fraction of the total electric production is tied to grid storage, with the vast majority 2 being pumped hydro installations. [3] While the latter technology is mature, cost effective, and efficient, it is geographically limited. [3] Alternate modes of energy storage that can be deployed in a distributed manner include batteries, compressed air, thermochemical energy, and flywheels. [3] Flow batteries are particularly attractive due to their decoupled energy and power, providing design flexibility especially at large scales. [4][5][6] Many flow battery chemistries, however, suffer from limited complex solubility and low nominal voltage, resulting in low energy densities. [7] To overcome this, Duduta et al. developed the semi-solid flow cell (SSFC), [8] in which traditional liquid catholytes and anolytes are replaced by attractive colloidal suspensions composed of Li-ion compounds. They also replaced traditional stationary current collectors with conductive carbon nanoparticle networks within the flowing suspensions. These suspensions, which take advantage of Li-ion battery's high energy density with flow battery's design flexibility, have been investigated both experimentally [8][9][10][11][12] and computationally. [10,13,14] Similar concepts have recently emerged for electrochemical flow capacitors [15] and polysulfide flow batteries. [16] To fully optimize SSFCs, the flowing electrodes must have high active material content coupled with an adequate conductive filler network to overcome the resistive nature of most electrochemically active Li-ion compounds. However, as their solids loading increases, dramatic changes in their rheological properties ensue, which inhibit flow. The key to maximizing active material content while retaining satisfactory flowability and conductivity is to simultaneously tailor the respective interactions between all particles present within these electrode suspensions.[17] 3Here, we report the design and characterization of biphasic SSFC electrode suspensions with high energy density, fast charge transport, and low-dissipation flow. To create these biphasic mixtures [18,19] we specifically tailor the interactions between the active particles, i.e., LiFePO 4 (LFP), to be repulsive, the interactions between the conductive particles, Ketjenblack EC-600JD (KB), to be attractive, and the cross-interactions between LFP-KB to also be repulsive. These two particle populations are suspended and mixed sequentially in propylene carbonate (PC) with 1M of lithium bis(trifluoromethane)sulfonamide (LiTFSI). It is well known that colloidal particles will rapidly aggregate when suspended in polar solvents under high ionic strength conditions due to van der Waals interactions.[20] Hence, we first introduce a non-ionic dispersant, polyvinylpyrrolidone (PVP), with appropriate amount to selectively stabilize ...

The paper presents a novel theoretical model of blistering initiation and propagation especially useful for coating life assessment. The focus is on initially circular blisters. A two-part theoretical analysis of blistering is conducted using mesomechanics approach coupling diffusion concepts with fracture mechanics concepts. The diffusion concept is used to treat the corrosive species transport, eventually causing corrosion and blistering, while the fracture mechanics concept is used to treat the blister growth as circular crack propagation. Effects of thickness ratio and modulus ratio on blistering propagation are discussed. A simple criterion is identified which excludes the possibility of widespread blister propagation. Furthermore, a comparative study with the existing blistering models is carried out. Experiments are reported for blistering using a model coating-substrate system, chosen to allow visualisation of interface and to permit coupled (diffusion and residual) stresses in the coating over a full range of interest. The predicted limits from theoretical model are expected to be useful for the manufacturers in the design and deposition of coatings.
