Analysis of Charge-Discharge Rate Influences LCO/Graphite Pouch Cell Volume Expansion During Rest Periods
Abstract Volume expansion during rest directly reflects internal polarization and lithium concentration gradients built up during charge or discharge — cells resting after a low-rate cycle show minimal volume change,...

In situ Gas Production Analysis Of Cell Anti-overcharge Electrolyte Additive
1. Preface When lithium-ion battery is overcharged, too many lithium ions take out out of the cathode material, and the voltage and temperature of the battery rise rapidly, releasing a...

Study On Mechanical Properties of Chemical Vapor Deposition Silicon-Carbon Anode Powder and Electrode Sheets
Abstract Among CVD silicon-carbon anode powder (vapor-deposited, PSC), milled silicon-carbon powder (SiC), and conventional artificial graphite (GR), graphite consistently shows the highest compaction density and greatest thickness rebound across 10–350 MPa applied pressure. Between...

Analysis of Electrical Conductivity and Compression Properties of Hard Carbon and Graphite Materials
Abstract Hard carbon vs graphite comparison across electrical conductivity, compaction density, and thickness rebound reveals a clear material division: graphite compaction density approaches 2.3 g/cm³ at high pressures with substantially higher electrical conductivity,...

Dry Electrode Process: PTFE Binder Fibrillation, In-Situ Resistivity, and Calender Pressure Optimization
Abstract The dry electrode process — a solvent-free manufacturing route that compresses active material, conductive additive, and PTFE binder directly onto a current collector without NMP coating and drying —...

The Differences in Electrochemical and Mechanical Performance of LMFP-Blended Cathodes with Varied Ratios
Abstract LMFP (lithium manganese iron phosphate) cathode charges to 4.1 V — 400 mV higher than LFP’s 3.7 V average discharge voltage — delivering 15–20% higher theoretical energy density than LFP...

Research on Correlation Between Cathode Powder Resistance and Electrode Resistance
Abstract Cathode powder battery testing using a controlled-pressure powder resistance measurement can predict a cathode material’s finished electrode resistance before slurry mixing and coating, because when the powder is compacted to a pressure...
