“…However, the largecapacity battery modulus claims more safety concerns, because fire or explosion at abnormal conditions may lead to serious hazards owing to the hidden peril of traditional liquid electrolyte system, i.e., lithium hexafluorophosphate solutions in aprotic organic solvents. This traditional liquid electrolyte system has been widely used in state of the art technology mainly owing to its high ionic conductivity (10 −3 -10 −2 S cm −1 ) at room temperature [3][4][5][6][7][8][9]. The use of a gel polymer electrolyte (GPE) in place of the liquid electrolyte may help to tackle safety concerns: (i) suppression of lithium dendrite growth that is usually caused by uneven currents when charged in the case of porous separators.…”

A single-ion gel polymer electrolyte of PLTB@PVDF-HFP (polymeric lithium tartaric acid borate@poly(vinylidene fluoride-co-hexafluoropropene)) was prepared and its ionic conductivity was optimized via solvent composition tailoring. It was manifested that the ethylene carbonate/dimethyl carbonate (EC/DMC) swollen PLTB@PVDF-HFP exhibited a superior lithium ionic conductivity at room temperature to that of the traditional liquid electrolyte system (1 M LiPF 6 /EC/DMC). The Li 4 Ti 5 O 12 /LiFePO 4 cells using the EC/DMC swollen PLTB@PVDF-HFP as polymer electrolyte showed stable charge/discharge voltage profiles with small voltage hysteresis, preferable rate capability and excellent cycle performance at room temperature. These superior performances of EC/DMC swollen PLTB@ PVDF-HFP could endow this class of gel polymer electrolyte a very promising alternative to state of the art liquid electrolyte system.

“…The porosity of cellulose/PSA (66%) was higher than that of PP separator (55%) indicating an enhanced permeability. 33 It was remarkable that the Gurley value of cellulose/PSA composite membrane (60 s) was much lower than that of PP separator (235 s). This result could be ascribed to the higher porosity and interwoven porous structure of cellulose/PSA membrane.…”

Battery separators have drawn considerable attention due to their vital roles for the safety and electrochemical performance of lithium-ion batteries. In this paper, the cellulose/polysulfonamide composite membrane was successfully fabricated from a mixture of microfibrillar cellulose and polysulfonamide via a facile papermaking process. And its potential application was explored as a high performance lithium-ion battery separator by characterizing their electrolyte wettability, heat tolerance, and electrochemical properties. Lithium cobalt oxide/graphite cells using the separator displayed better capacity retention ratios of 85% after 100 cycles and superior rate capability compared with those of a commercial polypropylene separator. Furthermore, the lithium iron phosphate/lithium half cell using cellulose/ polysulfonamide separator exhibited stable charge−discharge capability even at 120°C. It was demonstrated that the composite separator possessed an enhanced thermal dimensional stability. This research provides a promising new strategy for large-scale fabrication of high performance lithium-ion battery membranes.

“…Recently, various approaches to overcome these shortcomings of polyolefin based separators have been reported. Most reports focused on many alternatives of polyolefin based separators such as non-woven separators and inorganic composite [13][14][15][16][17][18]. Another recent approach was the coating of polyolefin based separators using inorganic particles due to the excellent thermal stability and wettability of inorganic particles with organic electrolytes.…”

The formation of SiO 2 nanoparticles with uniform particle size is accomplished through direct hydrolysis of tetraethyl orthosilicate (TEOS), while the deposition of the formed SiO 2 on PP separators was conducted in the same solution containing polyvinylidene fluoridehexafluoropropylene (PVDF-HFP) as binders and acetone as the solvent. The effects of the ceramic coating on the surface morphology, tensile strength, contact angles, electrolyte uptake, thermal shrinkage of the PP separators and the cell performances such as battery rate capability and Coulombic efficiency were investigated. The coated separators show significant reduction in thermal shrinkage and improvement in tensile strength, contact angles, electrolyte uptake and battery performance as compared to the plain PP separator.
