“…structural electrodes and BN/PVDF separator has good resistance to mechanical deformation and excellent electrochemical performance. Shi et al [199] designed a composite separator (vanadium nitride (VN)/PVDF-Polymethylmethacrylate (PMMA)/h-BN) with a 3D interconnected network structure by electrospinning and magnetron sputtering method. As shown in Figure 16c, the sandwich-type separator is composed of a VN layer near the sulfur cathode, a h-BN layer near the Li anode, and an intermediate layer, in which the VN can suppress the "shuttle effect" of PS, while h-BN can dissipate the heat generated during charging and discharging process and suppress the penetration of PS.…”

With the development of energy storage technology, the demand for high energy density and high security batteries is increasing, making the research of lithium battery (LB) technology an extremely important pursuit. However, the poor structural stability of electrode materials, high interfacial impedance between electrolyte and electrode, and the growth of lithium dendrites have seriously hindered the commercialization of LBs. Recently, due to their unique electronic structures and hybrid forms, boron‐based materials have been widely used in different LB components, such as electrodes, electrolytes, separators, additives, and binders, to resolve these problems. Here, a basic understanding of boron and boron‐based materials is first introduced. Subsequently, the recent research progress on the application of boron in each component of the LB is summarized, aiming to understand the hybrid forms of boron and their potential for use in LB materials. Finally, some new strategies and perspectives on the application of boron in LB materials are proposed. Here, the aim is to provide a clear insight on the study of boron in energy storage materials and contribute to the promotion of further research in this area.

“…However, it is possible to improve LiPS rejection by fabricating a PVDF-based copolymer NF. Shi et al [ 89 ] electrospun a PVDF/polymethylmethacrylate (PMMA) copolymer. The ester groups in the PMMA had higher binding energies for the LiPSs, resulting in improved rejection rates.…”

“…Inorganic nitrides such as TiN, ZrN, VN, and BN are promising materials for LSBs because of their high affinity for LiPSs, high electrical conductivity, and thermal stability [ 134 ]. Recently, Shi et al [ 89 ] coated a polyvinylidene fluoride-polymethylmethacrylate (PVDF-PMMA) NF separator with VN on the cathode side and BN on the anode side via magnetron sputtering. The addition of VN and BN did not significantly affect the porosity and slightly increased electrolyte uptake due to increased electrolyte affinity with the inorganic nitrides.…”

Lithium-Sulfur batteries (LSBs) are one of the most promising next-generation batteries to replace Li-ion batteries that power everything from small portable devices to large electric vehicles. LSBs boast a nearly five times higher theoretical capacity than Li-ion batteries due to sulfur’s high theoretical capacity, and LSBs use abundant sulfur instead of rare metals as their cathodes. In order to make LSBs commercially viable, an LSB’s separator must permit fast Li-ion diffusion while suppressing the migration of soluble lithium polysulfides (LiPSs). Polyolefin separators (commonly used in Li-ion batteries) fail to block LiPSs, have low thermal stability, poor mechanical strength, and weak electrolyte affinity. Novel nanofiber (NF) separators address the aforementioned shortcomings of polyolefin separators with intrinsically superior properties. Moreover, NF separators can easily be produced in large volumes, fine-tuned via facile electrospinning techniques, and modified with various additives. This review discusses the design principles and performance of LSBs with exemplary NF separators. The benefits of using various polymers and the effects of different polymer modifications are analyzed. We also discuss the conversion of polymer NFs into carbon NFs (CNFs) and their effects on rate capability and thermal stability. Finally, common and promising modifiers for NF separators, including carbon, metal oxide, and metal-organic framework (MOF), are examined. We highlight the underlying properties of the composite NF separators that enhance the capacity, cyclability, and resilience of LSBs.

Günümüz dünyasında sürekli artan enerji talebi ve karbon salınımının azaltılması zorunluluğu çeşitli zorluklar yaratmaktadır. Bu durum diğer enerji türlerine yani yenilenebilir enerji kaynaklarına yoğunlaşmayı ve etkin enerji depolamayı gerektirir. Üretilen enerji için yüksek güç yoğunluğu, uzun ömürlü ve uygun maliyetli depolama cihazları gerekmektedir ve bu ihtiyaca pil teknolojisi bir çözümdür. Lityum iyon pilleri (LİP) taşınabilir elektronik cihazlar için en popüler şarj edilebilir pillerdir. Yüksek elektrik yoğunluğa sahip olması aynı zamanda yüksek hızlı şarj özelliği, yavaş deşarj ve uzun ömürlü olması avantajlarındandır. LİP, NiCd pillerden daha pahalıdır, ancak daha küçük ve daha hafif olmakla birlikte daha geniş bir sıcaklık aralığında çalışır. Bu özellikler sayesinde LİP çok alanda kullanılmaya başlamıştır. LİP en büyük dezavantajı yüksek sıcaklıklarda bozulmasıdır. Bu sorunda pilin bileşenlerinin etkisi büyüktür. Ayırıcılar pillerin içindeki elektrokimyasal reaksiyona doğrudan dahil olmayan, elektrotlar arasındaki teması keserek dahili kısa devreleri önleyen, sıvı elektrolitleri depolayan, şarj-deşarj işlemleri sırasında iyonların verimli bir şekilde aktarılmasını sağlayan ve yüksek sıcaklıklarda LİP'lerin kullanımını mümkün kılan en önemli bileşenlerden biridir. LİP'lerde ayırıcı olarak çeşitli polimerler farklı hazırlama yöntemleri ile hazırlanarak kullanılmaktadır. Hekzagonal bor nitrür (hBN) ayırıcının ısıl kararlılığını artırmak, elektrolit ıslatılabilirliğini iyileştirmek ve özellikle yüksek sıcaklık ve yüksek şarj/deşarj akım hızlarında elektrokimyasal performansı iyileştirmek için polimerlerle kullanılması son yıllarda yoğun olarak çalışılmaktadır. Ayırıcıda hBN bulunduğunda daha homojen ısıl dağılım, Li birikiminin olmaması, artan çevrim sayısı ve kullanım ömründe artış gibi olumlu etkiler tespit edilmiştir. Bu derlemede hekzagonal bor nitrürün LİP'lerde ayırıcı içinde kullanımına ilişkin kapsamlı bir genel bakış sağlamaya çalışılmaktadır.
