The separator in a battery is often damaged because its material is easily crushed or broken. ... ... In the four core components of LIBs, the separators' primary function is to prevent physical contact with electrodes to avoid internal short-circuiting and offer a channel for lithium-ion transport [5,6].
The literature on lithium metal battery separators reveals a significant evolution in design and materials over time . Initially, separators were basic polymer films designed for lithium-ion batteries, focusing primarily on preventing short-circuits and allowing ionic conductivity [, , ].
This phenomenon is called separator breakdown, which is one step of the Li-ion battery thermal runaway process. Therefore, the thermal properties of sepa rators have a strong influence on battery safety. Numerical anism and give reliable prediction results. Other related performances such as ion by numerical methods. 2.3.1. Thermal Transport
The mechanical strength and thermal stability of the separator are the basic guarantees of lithium batteries’ safety. At the same time, the separator’s high porosity and electrolyte wettability are necessary conditions for the high electrochemical performance of lithium batteries . Fig. 1. (a) Schematic diagram for lithium battery.
Desired Characteristics of a Battery Separator One of the critical battery components for ensuring safety is the separator. Separators (shown in Figure 1) are thin porous membranes that physically separate the cathode and anode, while allowing ion transport.
To enhance the thermal stability of lithium-ion batteries (LIBs) , a novel ceramic-coated separator has been developed by integrating one-dimensional silica tubes (ST) onto one side of a commercial polyethylene (PE) porous separator (Fig. 5 b).
