Abstract Pouch cell swelling refers to the reversible and irreversible dimensional changes—in volume and thickness—that occur during lithium-ion intercalation and de-intercalation…
1. Author Information and Article Abstract CP Aiken (first author) and JR Dahn (corresponding author) of Dalhousie University in Canada introduced a device for in-situ gas product…
1. Abstract Gas evolution during overcharge is a critical safety and performance concern for lithium-ion cells. Using a dual-channel, temperature-controlled In-Situ Gassing Volume…
1. Preface Lithium-ion batteries undergo volume expansion during formation, cycling, storage, and overcharge, stemming from both structural changes and gas evolution. The charge d…
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, releas…
1. Preface Lithium iron phosphate (LFP cells), which typically use LiFePO₄ with an olivine structure coated onto aluminum foil as the cathode and graphite coated onto copper foil …
1. Preface Electrolyte is one of the four main materials of lithium-ion batteries, known as the “blood” of lithium-ion batteries. Electrolyte is mainly composed of org…
1. Introduction Formation is a critical manufacturing step for lithium-ion cells: its primary purpose is to generate a stable solid electrolyte interphase (SEI film) on the negati…
Abstract We report an in-situ study of Gas Generation and open-circuit voltage (OCV) behavior for lithium-ion cells stored at 85 °C across five states of charge (SOC). Using the I…
1. Background In recent years, people have placed higher and higher requirements on battery life, safety, fast charging and other performance. Silicon-based anode electrode materi…
