Suppressing the voltage-fading of layered lithium-rich cathode materials an aqueous binder for Li-ion batteries

Guar gum (GG) has been applied as a binder for layered lithium-rich cathode materials of Li-ion batteries for the first time. Compared with the conventional PVDF binder, electrodes with GG as the binder exhibit significantly suppressed voltage and capacity fading. This study has introduced a multi-f...

Description
Summary:Guar gum (GG) has been applied as a binder for layered lithium-rich cathode materials of Li-ion batteries for the first time. Compared with the conventional PVDF binder, electrodes with GG as the binder exhibit significantly suppressed voltage and capacity fading. This study has introduced a multi-functional binder for layered lithium-rich cathode materials. Guar gum (GG) has been applied as a binder for layered lithium-rich cathode materials of Li-ion batteries for the first time.
