Multifunctional separators offer new possibilities to the incorporation of ceramics into Li-ion battery separators. SiO 2 chemically grafted on a PE separator improves the adhesion strength, thermal stability (<5% shrinkage at 120 °C for 30 min), and electrolyte wettability as compared with the physical SiO 2 coating on a PE separator [ 49 ].
The battery separator is one of the most essential components that highly affect the electrochemical stability and performance in lithium-ion batteries. In order to keep up with a nationwide trend and needs in the battery society, the role of battery separators starts to change from passive to active.
It emphasizes their vital role in recycling and environmental sustainability. The battery sorting system typically operates by employing various sensors and sorting mechanisms to identify and separate different types of batteries based on unique and distinctive features, such as shape, chemistry, label, and internal structure.
The sample (battery) with the minimum euclidean distance to the corresponding center point indicates that it is included in this category. Therefore, all the samples with three characteristic parameters (capacity, internal resistance and LAM) can be classified into different categories to achieve multi-factor sorting for retired batteries. 3.2.
Step 1: Perform a feature extraction experiment on the second-use batteries that need to be sorted, so as to extract the sorting characteristic parameters of each battery. capacity test, HPPC test and low current discharging experiment are conducted to determine battery capacity, internal resistance and C loss, which is caused by LAM.
The major role of the battery separator is to physically isolate the anode from the cathode while allowing mobile Li-ions to transport back and forth . Unfortunately, two technical challenges associated with separator puncture and significant thermal shrinkage of polymer separators threaten the overall safety of batteries.
First, the functional separator can improve the safety of the batteries, but at the cost of battery performance. Second, it is difficult to improve the performance of the functionalized separator when taking industrial standards into consideration, such as electrolyte/sulfur (E/S) ratio in a Li-S cell.
