Microporous gel electrolyte Li-ion battery

Journal of Power Sources, 2004
Abstract This paper describes the fabrication and performance of microporous gel electrolyte (MGE) Li-ion batteries. Fabrication of the MGE battery includes three steps: (1) making a microporous membrane separator by the phase inversion method, (2) activating the battery with a liquid electrolyte, and (3) forming MGE in situ by cycling the battery ...

Gel polymer electrolytes based on PMMA

Electrochimica Acta, 2001
New polymer gels (based on PMMA/PC) containing Li, Na, Mg, and Zn perchlorates were prepared. The conductivity of gels containing cations of smaller ionic radii (Li and Mg) is lower than that of the others.

Electrochemistry of polyvinyl acetate gel electrolytes

Solid State Ionics, 2002
Abstract This paper describes the first example of polyvinyl acetate (PVAc) used as a gel electrolyte with a short-chain polyethylene glycol (MPEG-400) as a plasticizer. The polymer films are solid and sticky. Background cyclic voltammetry (CV) shows a potential window between +0.4 and −0.7 V vs. AgQRE.

Bacto agar-based gel polymer electrolyte

Ionics, 2011
The biopolymer of a Bacto agar-based gel polymer electrolyte (GPE) was prepared by addition of NaI and I2 as redox couple. The prepared GPE was characterized using impedance spectroscopy and X-ray diffraction (XRD) in order to determine its electrical and structural properties, respectively.
