TL;DR: In this paper, a review of a range of analytical studies and physical models for Li-S batteries is presented, showing that experimental understanding is well ahead of state-of-the-art models.

TL;DR: In this paper, the thickness variation of a Li-S pouch cell prototype was investigated using a laser gauge for monitoring the cell thickness variation under operation, and it was found that the thickness evolution of a complete pouch cell is mostly governed by Li anodes volume changes.

TL;DR: In this article, an integrated 2D model of a lithium ion battery is developed to study the mechanical stress in storage particles as a function of material properties, and the results show that the particle distance from the separator, in combination with the material properties of the particle, is critical in predicting the stress generated within the particle.

TL;DR: In this article, a linearized model is developed for lithium ion batteries, relying on simplified characterizations of lithium transport in the electrolyte and through the interface between the electrolytes and the storage particles of the electrodes, which can be used for both discharge and charging of the battery.

TL;DR: In this paper, the authors identify three non-dimensional parameters which govern the stress response within a spherical storage particle, and carry out numerical simulations to characterize the stresses that are developed using system properties such as the diffusion coefficient, particle radius, lithium partial molar volume and Young's modulus.
