“…It is well-known that a shift to lower wavenumbers and an increase in the intense of ν(CO) are associated with an increase in the polarity of the CO groups, which is ascribed to the presence of ethereal functional groups coordinating Li + cations. [30][31][32] These findings indicate that during charge-discharge process, the LCO particles transport Li + cations by coordinating CO functional group in PEO chains. Combined with observed continuous film of LCO-PEO composite cathodes, it is suggested that the formed 3D continuous ionic conductive network among the LCO particles promotes the Li + ion transportation via coordinating CO functional group in PEO chains thus enhancing the specific capacity of ASLBs.…”

All-solid-state lithium batteries (ASLBs) have been dramatically attracted recently for its ability of solving the safety issues in traditional lithium ion batteries using liquid electrolyte. However the poor Li + transportation between the active material particles in the cathode greatly deteriorate the specific capacity of ASLBs. Herein, we design a composite cathode composed of polyethylene oxide (PEO) and LiCoO 2 (LCO) in which a three-dimensional (3D) continuous Li + conductive network forms. With the decrease of the LCO: PEO ratio, the 3D Li + conductive network gradually becomes continuous, and the corresponding discharge capacity increase from 50 to 136 mAh g −1 . At LCO: PEO = 6:1 and 4:1, the corresponding ASLBs has a very high discharge capacity of 136 and 124 mAh g −1 , respectively, representing approximately 98% and 90% of the theoretical discharge capacity. The capacity retention after 5 cycles is 97%∼98% of the 2 nd cycle, which confirms stable cycle performance of the battery. The FTIR results show that, in the composite cathode, the LCO particles transport Li + cations by coordinating CO functional group in PEO chains. Compared with other optimized ASLBs based on LLZO solid elctrolyte, our battery has higher specific capacity while being tested under the highest current rate. Recently, the all-solid-state lithium batteries (ASLBs) based on solid electrolyte are receiving significant attention for its safety by the displacement of the volatile and flammable liquid electrolyte.1-4 To develop high performance ASLBs, three critical issues must be considered: (1) get a high lithium ionic conductivity solid electrolyte of 10 −2 ∼10 −3 S cm −1 at room temperature and stability against chemical reaction with lithium anode, (2) lower the interfacial resistance between the electrodes and solid electrolyte, (3) solve the problem of poor Li ionic transportation among active material particles in the cathode. However, the third issue is often overlooked.The garnet-type inorganic oxide lithium ion conductor, nominal Li 7 La 3 Zr 2 O 12 (LLZO), is highly expected to be used as the solid electrolyte to accelerate the development of ASLBs.5-8 Recent reports reveal that doping with elements such as Ga 3+ and Ta 5+ can improve its room temperature conductivity to 0.4∼1.0 × 10 −3 S cm −1 . 9,10The LLZO system is reported to be stable with Li metal anode as well as possessing high electrochemical window (vs Li > 5 v). 11 The wide electrochemical window allows the use of high voltage cathode materials which may result in a potential high specific capacity for ASLBs.So far, the interfacial resistance between the electrodes and solid electrolyte has become the main contributor to the internal resistance of ASLBs, especially the resistance between cathode and solid electrolyte. Electrochemical performance of ASLBs based on LLZO solid electrolyte has been constructed by some groups using various methods aimed at reducing the interfacial resistance.12-15 Tan et al.12 reported a proto-type Li/LLZO/LiCoO 2 (LCO) cell whic...

“…From elemental mapping by field‐emission scanning electron microscopy (FE‐SEM), it is clear that LiClO 4 was uniformly distributed in these COFs (Supporting Information, Figures S12–S14). Upon loading LiClO 4 , FTIR spectra revealed a new peak at 625 cm −1 , which was assigned to the ClO 4 − anion (Supporting Information, Figures S2–S4, red curves) . To confirm the thermal stability, we conducted the TGA analysis of Li + @TPB‐DMTP‐COF.…”

A strategy based on covalent organic frameworks for ultrafast ion transport involves designing an ionic interface to mediate ion motion. Electrolyte chains were integrated onto the walls of one‐dimensional channels to construct ionic frameworks via pore surface engineering, so that the ionic interface can be systematically tuned at the desired composition and density. This strategy enables a quantitative correlation between interface and ion transport and unveils a full picture of managing ionic interface to achieve high‐rate ion transport. Moreover, the effect of interfaces was scaled on ion transport; ion mobility is increased in an exponential mode with the ionic interface. This strategy not only sets a benchmark system but also offers a general guidance for designing ionic interface that is key to systems for energy conversion and storage.

Nanofibrous solid polymer electrolytes were prepared using the electrospinning method. These nanofibres were constructed from poly(ethylene oxide), lithium perchlorate and ethylene carbonate, which were incorporated with multi‐walled carbon nanotube (MWCNT) and graphene oxide (GO). The morphological properties of the as‐prepared electrolytes and the interaction between the components of the composites were characterized using scanning electron microscopy and Fourier transform infrared spectroscopy, respectively. X‐ray spectra and differential scanning calorimetry indicated an increase in amorphous regions of the nanofibrous electrolytes on addition of the fillers. However, the crystalline regions were increased on incorporation of fillers into polymeric film electrolytes. The conductivity values of the nanofibrous electrolytes reached 0.048 and 0.057 mS cm−1 when 0.35 wt% MWCNT and 0.21 wt % GO were introduced into the nanofibrous structures, respectively. The capacity and cycling stability of the nanofibrous electrolytes were improved by incorporation of MWCNT filler. Furthermore, stress and elongation modulus were improved at low MWCNT and GO filler contents. Results revealed that the nanofibrous structures could be promising candidates as solvent‐free electrolytes applicable in lithium ion batteries. © 2019 Society of Chemical Industry
