1. Preface With the increasing demand for lithium-ion battery end-products, lithium-ion battery performance also needs to be constantly improved, such as the structural stability of lithium-ion batteries, safety performance and appearance of the hardness and so on. Improving the cell…
1. Research Background In lithium-ion batteries, the anode material, as the main part of lithium ion diffusion and electron transport, determines the performance of the battery to a large extent. The ion diffusion characteristics of cathode have been a hot…
1. Preface The raw materials of lithium-ion batteries mainly include positive electrode materials, negative electrode materials, current collectors, electrolytes and separators. Cathode and anode electrode materials are usually micron-sized powder materials. Among them, common cathode electrode powder materials of lithium-ion…
1. Preface In this paper, we adopt the in-situ swelling analysis system(SWE Series) of IEST to monitor the pressure and thickness deformation of the battery by correlating the SOC and SOH parameters of a single battery, and evaluate the compression…
1. Preface Lithium-ion battery industry is one of the important directions affecting the development of the national economy at present, in the design and research process of lithium-ion battery, materials compaction density is one of the key indicators affecting the…
Brief: Lyten in the US is to acquire a local Cuberg battery plant being sold off by Northvolt. The deal will enable Cuberg‘s lithium metal battery plant in San Leandro to produce up to 200 MWh of lithium-sulfur batteries to meet the growing…
1. Preface The actual electrode process design, the active material, especially the cathode electrode material conductivity properties is relatively poor, the electronic transmission path is mainly realized through the conductive additives path, such as Figure 1 for the ideal state of…
First Author: Fang Youyou Corresponding Author: Su Yuefeng, Dong Jinyang, Chen Lai Publishing Unit: Beijing Institute of Technology, Beijing Institute of Technology Innovation Center Equipment Used: IEST Powder Resistivity & Compaction Density Measurement System (PRCD1100) 1. Research Background With the…
1. Background In this paper, we experimentally and introduce empirical equations to quantitatively measure the elastic-plastic mechanical behavior of LCO powders during compaction. Compaction of electrode powder is a process in which the powder is pressed down at a constant…
1. The Basic Properties Of Powder Materials With the rapid development of the lithium-ion battery industry, there are more and more safety problems in the use of batteries, in which the material problem is a major problem that can not…
