The poor compatibility between dimethyl methylphosphonate (DMMP)-based electrolytes and carbonaceous anodes was improved by optimizing the compositions of the electrolyte and the electrode. In the electrolyte, the contents of DMMP and ethylene carbonate had significant effects on both the safety characteristic and the compatibility with carbonaceous anode. For the spherical mesocarbon microbeads, a conductive composite system containing the flake graphite and the carbon nanoparticles was beneficial to the highest reversible capacity (330 mAh g -1 ). In the common graphite anode, the watersoluble binder was the better choice than poly(vinylidene fluoride) to suppress the reductive decomposition of DMMP. In brief, the optimized compatibility indicated an extensive prospect of the flame-retarded electrolyte in the battery industry.

A novel porous copper fiber sintered felt (PCFSF) has been used as catalyst support to construct a methanol steam reforming microreactor for hydrogen production. The Cu/Zn/Al/Zr catalyst was loaded on the PCFSF by means of a two-layer impregnation method. The ultrasonic water bath vibration method was employed to investigate the effect of porosity, catalyst loading, and sintering temperature on the loading performance of PCFSFs. The effective catalyst loading, being limited by porosity and pore size, was >92% in the lower porosity range of 70-80%, but significantly reduced in higher porosity ranges >80%. © 2013 WILEY-VCH Verlag GmbH & Co.
