“…The first study was conducted by Qiu et al [341]. In their study, the flow of electrolyte through the pore space in a vanadium redox flow battery [342] was modeled by the standard single-phase LB method with the species and charge transport being solved using the finite-volume method. Recently, Lee et al [92] successfully applied the pseudopotential multiphase LB method to simulate the dynamic behavior of a liquid electrolyte in the porous electrode of a lithium-ion battery, which is a member of rechargeable batteries family.…”

Over the past few decades, tremendous progress has been made in the development of particle-based discrete simulation methods versus the conventional continuum-based methods. In particular, the lattice Boltzmann (LB) method has evolved from a theoretical novelty to a ubiquitous, versatile and powerful computational methodology for both fundamental research and engineering applications. It is a kinetic-based mesoscopic approach that bridges the microscales and macroscales, which offers distinctive advantages in simulation fidelity and computational efficiency. Applications of the LB method are now found in a wide range of disciplines including physics, chemistry, materials, biomedicine and various branches of engineering. The present work provides a comprehensive review of the LB method for thermofluids and energy applications, focusing on multiphase flows, thermal flows and thermal multiphase flows with phase change. The review first covers the theoretical framework of the LB method, revealing certain inconsistencies and defects as well as common features of multiphase and thermal LB models. Recent developments in improving the thermodynamic and hydrodynamic consistency, reducing spurious currents, enhancing the numerical stability, etc., are highlighted. These efforts have put the LB method on a firmer theoretical foundation with enhanced LB models that can achieve larger liquid-gas density ratio, higher Reynolds number and flexible surface tension. Examples of applications are provided in fuel cells and batteries, droplet collision, boiling heat transfer and evaporation, and energy storage. Finally, further developments and future prospect of the LB method are outlined for thermofluids and energy applications.3

This article considers a model formulation and an adaptive observer design for the simultaneous estimation of the state of charge and crossover flux in disproportionation redox flow batteries. This novel nonaqueous battery chemistry allows a simple isothermal lumped parameter model to be formulated. The transport of vanadium through the porous separator is a key unknown function of battery variables and it is approximated in the space of continuous functions. The state and parameter observer adaptation laws are derived using Lyapunov analysis applied to the estimation error, the stability and convergence of which are proved. Numerical values of observer gains are calculated by solving a polytopic linear matrix inequality and equality problem via convex optimization. The performance of this design is evaluated on a laboratory flow battery prototype, and it is shown that the crossover flux can be considered a linear function of state of charge for this battery configuration during self-discharge.

“…Besides conventional lead or lithium systems, there exists a broad variety of flow and high-temperature batteries [1]. Among these, redox-flow batteries (RFBs) show interesting characteristics: low maintenance, deep-discharge tolerance, long cycle stability, and the ability to use a modular design for scale-up [2,3]. The all-vanadium redox-flow battery (VFB) is the most investigated RFB [4].…”

A thorough understanding of the flow characteristics of vanadium redox-flow batteries is essential for their improvement. With a combined approach of CFD simulations linked with optical measurements, the distribution in a carbon felt electrode of the vanadium electrolyte as well as of an alternative fluid substitute is compared and in all three dimensions analyzed leading to qualitatively consistent results. Yet, the experimentally observed partially inhomogeneous flow distribution is not predicted by the pseudo-homogeneous porous media CFD model.
