TL;DR: In this paper, the influence of different process parameters on the electric current and volume and surface charge density in the polymer jet was measured and the electric conductivity and permittivity were measured as well.

TL;DR: It is shown for the first time that pure poly(acrylic acid) (PAA), possessing certain mechanical properties comparable to those of CMC but containing a higher concentration of carboxylic functional groups, may offer superior performance as a binder for Si anodes.
Abstract: Si-based Li-ion battery anodes offer specific capacity an order of magnitude beyond that of conventional graphite. However, the formation of stable Si anodes is a challenge because of significant volume changes occuring during their electrochemical alloying and dealloying with Li. Binder selection and optimization may allow significant improvements in the stability of Si-based anodes. Most studies of Si anodes have involved the use of carboxymethylcellulose (CMC) and poly(vinylidene fluoride) (PVDF) binders. Herein, we show for the first time that pure poly(acrylic acid) (PAA), possessing certain mechanical properties comparable to those of CMC but containing a higher concentration of carboxylic functional groups, may offer superior performance as a binder for Si anodes. We further show the positive impact of carbon coating on the stability of the anode. The carbon-coated Si nanopowder anodes, tested between 0.01 and 1 V vs Li/Li+ and containing as little as 15 wt % of PAA, showed excellent stability duri...

TL;DR: In this paper, it was shown that pure spinel NiFe 2 O 4 nanoparticles with a diameter of 5∼30 nm and a specific surface area of 20.0∼55.2 m 2 /g could be produced by calcining the gel precursors with various molar ratios of polyacrylic acid (PAA) to total metal ions (0.5∼2.0) in air at 300°C for 2h.

TL;DR: The adsorption of Ni(II) on oxidized multi-walled carbon nanotubes (MWCNTs) as a function of contact time, pH and foreign ions in the absence and presence of polyacrylic acid (PAA) was studied.

TL;DR: In this article, a complete and permanent hydrophilic modification of polyethersulfone (PES) membranes is achieved by argon plasma treatment followed by polyacrylic acid (PAA) grafting in vapor phase.
