In the electrochemical model for spiral-wound lithium ion battery with porous current collectors, the porosity of the current collectors are assumed to be 0.54, that is ɛ 1 = ɛ 2 = 0.54. Though there is no data available for commercial porous current collectors, we took this value from the experimental data from Xu et al. [12]. 3.

This process produces more flexible, regular, or specially-shaped lithium batteries. Conclusion. The wound battery has a high internal resistance, which can be significantly decreased by improving the structure. An all-tab structure, for instance, can accomplish a comparable degree of internal resistance to a stacked structure, but it needs ...
Edge Effects in a Spirally Wound Lithium-Ion Battery Introduction Due to the large differences in length scales in a lithium-ion battery, with the thickness of the different layers typically being several orders of magnitude smaller than the extension in the sheet direction, a lithium-ion battery is often well represented by a one-dimensional model.
