Wang, Yuanhui; Hao, Liang; Bai, Minli published the artcile< Modeling studies of the discharge performance of Li-O2 batteries with different cathode open structures>, Product Details of C19H34O2, the main research area is lithium peroxide oxygen cathode open structure discharge performance.
A two-dimensional (2D) transient model is proposed to explore the effect of cathode open structure on the discharge performance of the non-aqueous lithium-oxygen (Li-O2) batteries. It is found that decreasing the cathode open hole width (Whole) enhances the O2 transport ability in the electrode, making O2 concentration and lithium peroxide (Li2O2) deposit uniformly distributed within the electrode. This is conducive to reducing the concentration polarization and extending the discharge capacity of the Li-O2 batteries. The cathode open structure with Whole = 0.2 mm is regarded as the optimized open mode (OOM) as Whole = 0.2 mm gives the battery superior discharge performance, and further reduction of Whole will not increase the battery discharge capacity significantly. The Li-O2 battery with OOM has a pronounced increase in the discharge capacity under both pure O2 and air environments. The battery discharge capacity promotion by OOM is more remarkable if using DMSO electrolyte in the air environment and at a high c.d. of 4.0 A m-2. Therefore, the optimization of the cathode open structure is an effective way to improve the discharge performance of the Li-O2 batteries, especially operating in a low O2 environment.
