The separator is a key component for rechargeable batteries. It separates the positive and negative electrodes to prevent short-circuit of the battery and …
An electrospun nanofiber-coated Celgard® 2400 polypropylene microporous battery separator was prepared using polyvinylidene fluoride (PVDF) and polyvinylidene fluoride-co-chlorotrifluoroethylene (PVDF-co-CTFE). The coating of PVDF and PVDF-co-CTFE nanofibers was carried out using single nozzle and nozzle-less …
Lithium-ion batteries (LIBs) are energy-storage devices with a high-energy density in which the separator provides a physical barrier between the cathode and anode, to prevent electrical short circuits. To meet the demands of high-performance batteries, the separator must have excellent electrolyte wettability, thermotolerance, mechanical …
Current lithium-ion battery separators made from polyolefins such as polypropylene and polyethylene generally suffer from low porosity, low wettability, and slow ionic conductivity and tend to perform poorly against heat-triggering reactions that may cause potentially catastrophic issues, such as fire. To overcome these limitations, here …
This study intends to demonstrate the feasibility of a hot-pressed cathode/separator cell stack to improve the energy density of all-solid-state batteries in two ways. First, hot pressing substantially reduces porosity in both the cathode composite and the 1
The hot pressing of the pure PVDF and the PVDF nanocomposite films was per-formed using a 25T Hydraulic Laminating Hot Press (MTI Corporation). Following this, 2 × 2 cm reference samples were cut from each …
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. ...
