Summary: Nanoporous-crystalline (NC) alpha and beta forms of Poly(2,6-dimethyl-1,4-phenylene) oxide (PPO) can include low-molecular-mass guests. The transitions between alpha and beta forms can be achieved by sorption of beta-guests and alpha-guests. The loss of crystalline phase orientation occurs during the transitions and is only observed for guests that are good PPO solvents.

Summary: The sorption of pure CO2, CH4, and CO2/CH4 binary gas mixtures in amorphous glassy PPO was studied at 35 degrees C up to 1000 Torr. A combination of barometry and FTIR spectroscopy in the transmission mode was used to measure the sorption of gases in polymers. The solubility of CO2 in the binary mixtures was found to be similar to that of pure CO2 up to a total pressure of 1000 Torr and for CO2 mole fractions of about 0.5 and 0.3. The NET-GP modeling approach was employed to fit the solubility data of pure gases and to predict the solubility of CO2/CH4 mixed gases in PPO, with a deviation of less than 9.5% from experimental results for CO2 solubility.

Summary: In this study, a uniformly blended membrane was fabricated by incorporating chloromethylated triptycene and brominated poly(2,6-dimethyl-1,4-phenylene oxide) (BPPO). The dual-quaternized BPPO/triptycene-Cl blended membrane showed enhanced hydroxide ion conductivity and improved water electrolyzer cell performance compared to a commercial membrane. The dimensional stability of the blended membrane was effectively controlled, despite high water uptake, due to the increased free volume provided by the triptycene additive.

Summary: This study focuses on the melting behavior of nanoporous-crystalline (NC) and co-crystalline (CC) PPO films using differential scanning calorimetry. Results reveal that PPO films with c(//) orientation help establish melting temperatures of CC phases and achieve partially filled CC PPO films with lower melting temperatures through annealing. Molecular volumes suitable for guests of the alpha NC form of PPO are found to be in the range of 160-230 angstrom(3).

Summary: Four different preparation methods for nanoporous-crystalline films of PPO with high crystallinity and high c-perpendicular orientation, even for thickness as low as 5 μm, are described in this paper. The results support the hypothesis that the c-perpendicular orientation is due to the formation of flat-on crystalline lamellae through nanoconfined co-crystallization of PPO. An anomalous temperature dependence of c-perpendicular orientation for limonene-induced co-crystallization with PPO is also explained.

Summary: This study developed a thermal percolation strategy to fabricate a dual-conductive framework to address the issues of uncontrollable lithium deposition and severe dendrite formation in lithium metal batteries. By melting the antiperovskite superionic conductor, it can permeate into the electronically conductive scaffold, creating percolative electron/ion pathways. The hybrid material demonstrated the ability to spatially guide lithium deposition and suppress lithium dendrite growth. Experimental results showed that the MXA-antiperovskite electrodes exhibited superior cycling stability and high energy/power densities.

Summary: In this study, a self-decoupling strategy was proposed to improve the stability of bifunctional catalysts in zinc-air batteries. A smart interface with a resistance-switchable sulfonic acid doped polyaniline nanoarray interlayer was constructed in the bifunctional air electrode, allowing the spontaneous electrochemical decoupling of the bifunctional catalyst for the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER), respectively. This resulted in a mild-acidic zinc-air battery with stable cyclic performances, negligible energy efficiency loss, and a significantly longer cycle life compared to conventional zinc-air batteries.

Summary: The sluggish kinetics of sulfur reactions on the cathode and the inadequate lithium deposition/stripping reversibility on the anode are successfully mitigated by using a single cathode modifier, In2Se3, which catalyses the polysulfide reactions on the cathode and improves lithium deposition/removal reversibility on the anode through the formation of a LiInS2/LiInSe2 containing solid electrolyte interface. This single modification approach shows excellent performance in Li-metal anode-free Li-S batteries, achieving 60% capacity retention and an average Coulombic efficiency of 98.27% after 160 cycles.

Summary: Neutral/near-neutral electrolyte rechargeable zinc-air batteries (NN-ZABs) with long cycling lifetime have been hindered by the sluggish kinetics of oxygen electrocatalysis. A dynamic self-catalysis strategy is proposed to enhance the energy efficiency of NN-ZABs, based on in situ reversible generation of highly active electrocatalysts from the electrolyte. By integrating reversible redox reactions of Cu(i)/Cu(ii) and Mn(ii)/Mn(iv) with oxygen electrocatalysis, Cu(i)-O-Cl deposits are formed during discharge and Cu-MnO2 deposits are formed during charging, directly catalyzing oxygen reduction and oxygen evolution reactions. The in situ generated electrocatalysts exhibit good oxygen electrocatalytic activities due to their distinctive surface structures and can be dissolved by potential reversal. The designed NN-ZABs achieve a record-high energy efficiency of 69.0% and a cycling life of 1800 h with an areal capacity of 10 mA h cm(-2), outperforming previous NN-ZABs with preloaded electrocatalysts.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

Summary: By coupling electrochemical testing to operando synchrotron based X-ray absorption and powder diffraction experiments, blended positive electrodes consisting of LiMn2O4 spinel (LMO) and layered LiNi0.5Mn0.3Co0.2O2 (NMC) were studied to understand their redox mechanism. It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
