چکیده
This article offers insight into the role of binders in overall performance a dual-ion battery (DIB). Replacing sodium carboxymethyl cellulose (CMC) with poly(vinylidene fluoride-co-hexafluoropropylene) (PVdF-HFP) enhances interfacial stability graphite positive electrode DIB. Electrochemical testing combined X-ray photoelectron spectroscopy (XPS) and operando pressure measurements highlight that PVdF-HFP suppresses parasitic reactions at cathode-electrolyte interface (CEI), sharp contrast CMC. However, CMC causes less resistance is hence beneficial terms rate capability.

Ni-Composite Microencapsulated Graphite as the Negative Electrode in Lithium-Ion Batteries II. Electrochemical Impedance and Self-Discharge Studies
Electrochemical impedance and self-discharge studies were carried out to investigate lithium intercalation into bare and Ni-coated KS10 graphite. Values of the charge-transfer resistances, exchange current densities, surface film resistances, and lithium-ion diffusion coefficients as functions of the state of charge (SOC) all favored the 10 wt % Ni composite KS10 graphite over bare KS10 graphit...
