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…
1. Research Background At present, the cathode materials of lithium-ion batteries are mainly lithium cobalt oxide (LCO), ternary materials (NCM) and lithium iron phosphate (LFP). In the past one or two years, with the increase of electric vehicles and the…
1. Preface Lithium-ion battery R&D production process found that the conductivity of the cathode and anode active material particles can not meet the requirements of the electron migration rate, so the battery manufacturing process needs to add a conductive agent,…
1. Research Background High-nickel cathode materials are widely recognized as a popular choice of cathode materials for high-energy-density lithium-ion batteries due to their high capacity and low-cost benefits. However, fast charging and long cycling at high voltage can trigger serious…
1. Preface There are three main encapsulation forms for lithium batteries, namely pouch cell, prismatic cell and cylindrical cell. pouch cells use aluminum-plastic film as the encapsulation material, which provides design flexibility and a variety of models, and the shape…
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 (such as Al or Cu), such as Figure 1 for…
