1. Introduction With the rapid development of the lithium-ion battery industry, concerns over safety and stability during battery use have grown significantly. The primary causes of performance degradation in lithium-ion…
1. Introduction Recently, BYD’s “Megawatt Flash Charging” technology has attracted significant attention in the lithium battery field. Its “5-minute charge for 800-mile range” oil-electric equivalent technology is as strategic as…
1. Introduction: Conductive Additives—The “Invisible Bridge” in Lithium Batteries In lithium battery electrodes, conductive additives and binders are mixed to form a continuous carbon-binder domain (CBD), with active material particles…
1. Background The intercalation/deintercalation or deposition/stripping of lithium ions, along with side reactions such as continuous growth of the SEI film and gas generation, can induce internal pressure in batteries.…
1. Preface Electrolyte is the core part of lithium-ion battery research and development, which is not only an important medium to ensure ion transmission, but also an important foundation for…
1. Composite Fluid Technology Background Composite current collector is a “sandwich” structure, the inner polymer polymer layer (such as PET, PP or PI), both sides of the metal conductive layer…
1. Preface In this paper, we explore the correlation between electrolyte wettability and electrode tortuosity by testing the tortuosity and wetting rate of electrodes with different compaction densities to provide…
1. Preface The degree of electrolyte wetting is one of the key factors affecting the performance of lithium-ion batteries such as kinetics, cycle life, and safety and reliability, etc. A…
1. Preface By analyzing the correlation between the electrode tortuosity and the rate performance of the battery, this paper can preliminarily judge the rate performance of the battery at the…
1. Preface In this paper, the resistance difference of carbon coated aluminum foils with different formulations and different coating thicknesses is compared by using the electrode resistance test method to…
