Avant de plonger en profondeur dans les différents types de batteries au lithium et leurs graphiques de tension, il est essentiel de comprendre les implications plus profondes de ces données pour comprendre les performances, l'entretien de routine et les réparations de la batterie.
1. Introduction Lithium-ion batteries possess a high potential for the storage of renewable energy and for application inhybrid electric vehicles. They exhibit a high energy density and a low weight, making them valuable for application in mobile electronic devices.
See Fig. 1 a for the cross section of the building block of the lithium-ion battery cells with the arrangement of electrode/separators in alternating metal, granular material, and porous polymeric layers. Additional inadequacy of these models were a result of considering a rigid perfectly plastic response under tension.
In this article, we will take a look at the solutions ideal for tension, puncture, and peel testing of those batteries. A test solution for the lithium-ion battery industry would typically consist of material testing machine, fitted with a high accuracy load cell, analytical software and grips suitable for securing the battery during the test.
In this article, we will go through the grip recommendations to the most common tests types within lithium-ion battery testing. These are tension, puncture, and peel.
The homogenized response of a cell, which is a volume average of its' component's behavior, is highly dependent on the nature and orientation of the applied load. The multi-material, multi-layer building block of lithium-ion batteries consists of layers of electrodes and separators.
Lithium-ion batteries possess ahigh potential for the storage of renewable energy and for application in hybrid electric vehicles. They exhibit a high energy density and a low weight, making them valuable for application in mobile electronic devices. Major disadvantage of these batteries is, however, their gradual loss of capacity over lifetime.
