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 be ignored, th…
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 a…
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 …
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 cycli…
1. Preface Powder materials’ resistivity and compaction density are important indicators for material monitoring in the current lithium industry, and their determination is usually done under different quantitative pressures. The process of po…
1. Preface This paper mainly combines different doping ratios of silicon-carbon materials and different sintering processes of silica-based materials, combined with scanning electron microscopy, powder conductivity, compaction density and other test…
Literature Appreciation: Pressure Effect on Mechanical and Electrochemical Properties of Lithium Cobalt Oxide Powder Materials 1. Article Overview The design, manufacture and handling of active substance powders have a huge impact on battery perform…
1. Preface In the manufacturing process of lithium batteries, compaction density significantly influences battery performance. Generally, compaction density is closely related to the specific capacity, efficiency, internal resistance, and cycling pe…
In order to improve the bulk energy density of lithium-ion batteries, researchers mainly focus on two aspects: Increase the gram capacity of cathode and anode electrode materials; Increase the compaction density of cathode and anode electrodes. The …
This paper tests the powder compaction density and conductivity of graphite and LFP materials, and analyzes the differences between the two test methods. Measurement methods of compaction density and resistivity of lithium electric materials, detail…
