“…The reason of the granule formation is mainly the deposition of PES-C from polymer solution. This phenomenon is similar to PVDF/PSF blend membrane reported by Cheng et al [19]. In the primary polymer dope, PEC-C molecules stretch adequately and entangle with PVDF molecules.…”

“…Cheng et al [19] found that the addition amount of PSF in PVDF solution was only 2% when diethylene glycol dibenzoate (DEDB) and dibutyl phthalate (DBP) were selected as mixed diluents. SEM study showed that the PSF formed "sphericalshaped aggregates" when PSF content in casting solution reached 1.6%.…”

“…The selection of diluent used in TIPS method is essentially difficult to find blending polymers in TIPS process [17,18]. Cheng et al [19] found that polysulfone (PSF) formed "spherical-shaped aggregates" by using diethylene glycol dibenzoate (DEDB) and dibutyl phthalate (DBP) as mixed diluents when 1.6% PSF was added in PVDF solution. Polyethersulfone (PES) was a good blend material to overcome the shrinkage shortcoming of PVDF membrane in NIPS process [20].…”

Mesoporous silica was prepared from anorthite-clay via mechanical activation (i.e., grinding) and selective acid leaching method. The pore characteristics of the mesoporous silica with different grinding time and acid treatment time were systematically characterized and compared with those prepared via heat treatment followed by acid treatment. Particle size, X-ray diffraction (XRD), BET surface area, thermal gravity (TG), and solubility analyses were carried out to characterize the samples. The XRD results showed that grinding and heat treatment dramatically altered the crystal structure of the samples, resulting in the change in weight loss curves of the corresponding samples from TG analysis. The results for pore size distribution of the prepared samples revealed that acid-treatment led to significant changes in the pore structure of the samples while grinding and heat-treatment without acid-treatment showed negligible influence on the pore structure. More specifically, acidtreatment increased the specific surface area of the ground and heat-treated samples regardless of acid-treatment. Furthermore, solubility tests for anorthite-clay samples showed that there is a positive relationship between the solubility of anorthite-clay and the specific surface area of mesoporous silica, indicating that the increase in the specific surface area of mesoporous silica was attributed to the increase in the solubility of anorthite-clay.

A thermally stable and flame-retardant separator is proposed to improve the safety of lithium ion batteries. The separator is prepared by dip-coating both sides of a conventional tri-layer polyolefin separator with brominated poly(2,6-dimethyl-1,4-phenylene oxide) (BPPO). Significantly reduced thermal shrinkage and flammability are exhibited without decreases in the pore size or porosity of the conventional separator. By using the BPPO-coated separator, an electrochemical half-cell composed of a lithium metal anode and a LiCoO 2 cathode are successively tested. The resulting stable cycle performances are demonstrated. It is expected that the BPPO-coated separator can be a capable candidate as a separator for the safe of lithium ion batteries.
