What is the manufacturing process of battery separators?
The manufacturing process of battery separators can be broadly categorized into two methods: wet and dry. The wet process is widely used for manufacturing battery separators, especially polymeric materials. Polymer Solution Preparation: The first step in the wet process involves preparing a polymer solution.
How does a battery separator work?
As one essential component of the rechargeable batteries, the main function of the separator is to separate the positive and negative electrodes, restrict the free pass of electrons and prevent short-circuit of the battery. At the meantime, it allows the metal ions in the electrolyte to migrate freely between the electrodes [21, 22].
What is a rechargeable battery separator?
Separator is critical to the performance and safety of the rechargeable batteries. The design principles and basic requirements for separators are overviewed. The modification strategies in tailoring the separators' properties are discussed. Separators with high-temperature resistivity and better safety are desirable.
How to make a ceramic battery separator?
The dry process is commonly employed for manufacturing ceramic-based battery separators. Powder Mixing: The first step in the dry process is to mix the ceramic powders with binders and additives. The composition of the mixture is carefully controlled to achieve the desired properties in the final separator.
How to improve the performance of a rechargeable battery separator?
In order to obtain a rechargeable battery with higher performance, the performance of the separator needs to be further improved. The function of the existing separator can be improved by grafting, compounding, blending, filling and ionic liquid modification.
What is the thermal shrinkage of a battery separator?
The thermal shrinkage of the separator is required to be <5% in both MD and TD directions after heating for 60 min at 90 °C (in a vacuum) . In rechargeable batteries, the separator is required to be able to cut off the current loop before it reaches the thermal runaway temperature when the battery system is abnormal and the temperature rises.
