TL;DR: In this article, only 2% (by weight) functional conductive polymer binder without any conductive additives was successfully used with a micron-size silicon monoxide (SiO) anode material, demonstrating stable and high gravimetric capacity (>1000 mAh/g) for ∼500 cycles and more than 90% capacity retention.

TL;DR: In this paper, the authors proposed a non-aqueous electrolyte secondary battery, which is composed of a silicon system negative electrode material (3), a nonaqueous ionic electrolyte (5), and a positive electrode material having an electromotive force of 3 V (vs. Li/Li+) or more.

TL;DR: When compressed to an appropriate density, an improved cycling performance and increased energy density are shown compared to the uncalendered electrode and overcalendered electrode.

TL;DR: In this article, the authors used an operando X-ray diffraction (XRD) technique to identify crystalline lithium disulfide (Li2S2) as a transient species in the lithium-sulfur cell.

TL;DR: In this article, the authors proposed a process for purifying raw carbon nanotubes to obtain an content in metallic impurities comprised between 5 ppm and 200 ppm, which can then be used to manufacture an electrode destined to a lithium-ion battery.
