1. Preface The silicon-carbon anode prepared by chemical vapor deposition (CVD), also known as vapor-deposited silicon anode, is a silicon-based anode material obtained through the chemical vapor deposition (CVD) process. The core of this preparation method involves storing silicon in…
1. Preface This paper compares the effects of flat-compaction and roller pressing on the compaction density and resistivity of the graphite electrode to provide reference data for battery designers. Battery energy density has always been one of the hotspots in…
1. Background Lithium-ion battery raw materials mainly include cathode materials, cathode materials, fluid collection, electrolyte and diaphragm. Positive and negative electrode materials are usually micron-grade powder materials, among which the common lithium-ion battery cathode powder materials are layered lithium cobalt…
1. Background With the rapid development of the new energy industry, the market demand for lithium-ion batteries is also increasing. Due to the raw material resource limitations and cost issues of lithium-ion batteries, sodium-ion batteries have also gradually received the…
1. Preface In recent years, with the continuous development of the new energy industry, new technologies have been continuously introduced, including the 46-series large cylindrical all-tab battery and semi-solid/solid-state batteries. Among these, the dry electrode process has unparalleled advantages over…
1. Preface With the rapid development of the new energy industry, lithium-ion powered vehicles have been widely used, and the safety performance of lithium-ion batteries has become increasingly important. During the long-term charge and discharge cycle of a module composed…
1. Preface In this paper, the resistivity, compaction density, and stress-strain curves of anode materials mixed with different ratios of LMFP and NCM under different pressures were investigated by using the Powder Resistivity & Compaction Density Meter (PRCD3100, IEST) and…
1. Preface With the rapid development of the lithium battery industry, lithium-ion batteries have been widely used in mobile phones, computers, automobiles, energy storage and other fields. Users have higher and higher requirements for fast charging of the battery, and…
1. Background Lithium-ion batteries dominate new energy power and storage devices due to their high energy density, high power, and long cycle life. As commercial lithium-ion batteries evolve, the industry demands increasingly stringent manufacturing costs, performance and longevity. Innovative, reliable,…
1. Preface As one of the crucial components of lithium-ion batteries, the separator directly affects key performance indicators such as current, capacity, and cycle life [1]. The separator should possess the following characteristics to meet battery requirements: (1) excellent wettability…
