“…In addition to the contact angle, the wettability of the separator can also be measured by finding the value of the electrolyte absorption capacity. This value can be found by measuring the mass of the separator before and after immersing it in a liquid electrolyte for two hours [17]. Furthermore, the value of electrolyte absorption capacity (EAC) can be found using Equation (1) [20]- [22].…”

The trend of using electric vehicles is increasing. With the increasing use of electric vehicles, it is necessary to master the key technologies used by electric vehicles, one of which is batteries, especially lithium-ion batteries (LiB). There are many important components in the LiB, one of which is a separator that serves to block short circuits between the anode and cathode of the battery while providing a way for ion exchange to continue. This article summarizes important information related to battery separator technology. The information includes the materials that have been used in commercial products and those of under research and development. In addition, the method of fabricating the separator using conventional methods and 3D printing is discussed. Finally, this article also discusses how several studies perform performance tests on separator materials. Keywords: battery separator, fabrication, materials, performance test, lithium-ion battery.

“…J. Li et al [169] presents the use of free-standing cellulose nanofiber to reduce polysulfide shuttle effect and dendrite growth, which results in an increase in discharge capacity. S. Thiangtham et al [170] presents the use of bio-membranes based on a sulfonated cellulose blend that provides a variety of characteristic improvements, such as better ionic conductivity, higher discharge rate and better capacity retention whilst increasing porosity.…”

As renewable energy sources, such as solar systems, are becoming more popular, the focus is moving into more effective utilization of these energy sources and harvesting more energy for intermittency reduction in this renewable source. This is opening up a market for methods of energy storage and increasing interest in batteries, as they are, as it stands, the foremost energy storage device available to suit a wide range of requirements. This interest has brought to light the downfalls of batteries and resultantly made room for the investigation of ultra-capacitors as a solution to these downfalls. One of these downfalls is related to the decrease in capacity, and temperamentality thereof, of a battery when not used precisely as stated by the supplier. The usable capacity is reliant on the complete discharge/charge cycles the battery can undergo before a 20% degradation in its specified capacity is observed. This article aims to investigate what causes this degradation, what aggravates it and how the degradation affects the usage of the battery. This investigation will lead to the identification of a gap in which this degradation can be decreased, prolonging the usage and increasing the feasibility of the energy storage devices.

“…Among all others, polylactic acid (PLA) is another valuable alternative: it is a biocompatible and biodegradable polyester used in different fields, ranging from biomedical to packaging and automotive applications . Currently, only few examples of the use of PLA as LIB separators have been reported in the literature focusing on the use of pure enantiomeric forms of PLA. − …”

This work concerns the study of electrospun scaffolds as separators for aprotic lithium-ion batteries (LIBs) composed of the amorphous poly-d,l-lactide (PDLLA), in solution concentrations of 8, 10, and 12 wt % and in different ratios with cellulose nanocrystals (CNCs). PDLLA has been studied for the first time as a separator, taking into account its amorphous character that could facilitate electrolyte incorporation into the polymer matrix and influence ionic conductivity, together with CNCs, for reducing the hydrophobicity of the scaffolds. The embedding of the nanocrystals in the scaffolds was confirmed by X-ray diffraction analysis and attenuated total reflectance Fourier transform infrared spectroscopy. The polymer combination influenced the nanofibrous morphology as evaluated by scanning electron microscopy and modulated the electrochemical behavior of the membranes that was investigated through linear sweep voltammetry, cyclic voltammetry, and electrochemical impedance spectroscopy tests. Among the studied categories, the P12 series displayed a nonhomogeneous electrolyte resistance and electrochemical stability, differently from P10, whose results suggested their application in LIBs with standard formulation, as confirmed by a preliminary performance test of the P10N6 formulation in a full Li-ion cell configuration.
