“…As discussed above, cellulose nanocrystals 264,311,312,[613][614][615][616] can be used as the reinforcing phase in a PEO matrix, and other natural polymers like chitosan, 617-619 chitin, 315 and natural rubber 620 were also able to be used to prepare the PEO-based electrolytes. Gerbaldi et al [621][622][623][624] prepared composite membranes based on microfibrillated cellulose in the presence of bisphenol A ethoxylate dimethacrylate (BEMA) and POEM by a free radical photopolymerization, and investigated the use of paper sheets to reinforce gel polymer electrolytes for Li-ion cells. The film showed excellent mechanical properties and good ionic conductivity values of ~10 -4 S cm -1 .…”

Poly(ethylene oxide)-based electrolytes for lithium-ion batteries

This article reviews the PEO-based electrolytes for lithium-ion batteries.Poly(ethylene oxide) (PEO) based materials are widely considered as promising candidates of polymer hosts in solid-state electrolytes for high energy density secondary lithium batteries. They have several specific advantages such as high safety, easy fabrication, low cost, high energy density, good electrochemical stability, and excellent compatibility with lithium salt. However, the typical linear PEO does not reach the production requirement because its insufficient ionic conductivity due to the high crystallinity of the ethylene oxide (EO) chains, which can restrain the ionic transition due to the stiff structure especially at low temperature. The scientists have explored different approaches to reduce the crystallinity hence to improve the ionic conductivity of PEO-based electrolytes, including: blending, modifying and making PEO derivatives etc. This review is focused on surveying the recent developments and issues about PEO-based electrolytes for lithium-ion batteries.

“…Currently used inorganic fillers include inert fillers with lower ionic conductivity and active fillers with higher ionic conductivity, also known as fast ion conductors 15 . Li 7 La 3 Zr 2 O 12 , 16 LiAlO 2 , 17 Li 1.5 Ge 2 (PO 4 ) 3 , 18 Li 3 N, 19 Al 2 O 3 , 20 TiO 2 , 21 ZrO 2 , 22 SiO 2 , 23 ferroelectric material, 24,25 etc., can properly improve the ionic conductivity and material stability. However, whether active or inert fillers are added to the polymer in the form of randomly distributed nanoparticles, the agglomeration of fillers will be caused by the excessive addition of fillers, which leads to long migration paths and high transport resistance of lithium ion in electrolyte 26 .…”

Summary Polymer solid electrolyte with high ionic conductivity at room‐temperature is most likely to be widely used in solid‐state lithium batteries. In this work, the novel surface lithiated TiO2 nanorods were firstly used as ionic conductor in polymer solid electrolyte. The surface lithiated TiO2 nanorods‐filled polypropylene carbonate polymer composite solid electrolyte (CSE) has an uniform composite structure with a thickness of about 60 μm. The ionic conductivity at room‐temperature is 1.21 × 10−4 S cm−1 and the electrochemical stability window is up to 4.6 V (vs Li+/Li). The assembled NCM622/CSE/Li solid‐state battery shows a stable cycle performance with a retention capacity of 120 mAh g−1 after 200 cycles at the current density of 0.3 C and a high coulomb efficiency of 99%. Compared with TiO2 particles, this novel surface lithiated TiO2 nanorods can provide more continuous ion transport channels and more Lewis acid‐base reactive sites, provide a novel way to enhance the lithium ion transport in polymer solid electrolyte.

“…In addition, many external conditions also affect the performance of materials, such as freezing, heat, physical design, and chemical corrosion [7,11,[15][16][17]. To overcome the poor hydrophilicity of polyolefin separators, many efforts have been made to characterize the electrochemical performances and mechanical properties, such as the plasma modified graft [18], ultraviolet irradiation [19], and electron beam irradiation [20]. However, these modified methods require expensive equipment and complex procedures.…”

Self-Polymerized Dopamine Nanoparticles Modified Separators for Improving Electrochemical Performance and Enhancing Mechanical Strength of Lithium-Ion Batteries

et al. 2020

Separators in lithium-ion batteries (LIBs) play an important role for battery safety, so stable electrochemical performance and high mechanical strength of separators will always be of interest. On the basis of the fact that polydopamine (PDA) nanoparticles found in mussel have a strong adhesion ability, biomaterial surface nanoparticles modification methods are developed to increase electrochemical performance and enhance mechanical strength of polypropylene (PP) and polypropylene/polyethylene/polypropylene (PP/PE/PP) separators. The electrolyte uptake performance, ionic conductivities, discharging rate capabilities, yield stresses, and failure strains of PP and PP/PE/PP separators are all enhanced remarkably by PDA modification. Thermal shrinkage results show that thermal stabilities and the shrinkage percentage of PDA-modified separators are improved. The electrochemical testing results conclude that the discharging capacities of PP (increased by 3.77%~187.57%) and PP/PE/PP (increased by 2.31%~92.21%) separators increase remarkably from 0.1 C to 5.0 C. The ionic conductivities of PDA-modified PP and PP/PE/PP separators are 1.5 times and 6.1 times higher than that of unmodified PP and PP/PE/PP separators, which in turn increase the electrolyte uptake and ionic migration. In addition, mechanical properties of PP (yield stresses: 17.48%~100.11%; failure stresses: 13.45%~82.71%; failure strains: 4.08%~303.13%) and PP/PE/PP (yield stresses: 11.77%~296.00%; failure stresses: 12.50%~248.30%; failure strains: 16.53%~32.56%) separators are increased greatly.
