Effect of Polymer Dispersant Addition on Functional Carbon Black Dispersion Behavior and Li Ion Battery Performance
نویسندگان
چکیده
In order to apply advanced carbon black with high surface area Li-ion battery (LIB) electrode, the effect of polymer dispersant addition into raw materials suspension on LIB performance was investigated. Four kinds dispersants, polyvinyl pyrrolidone (PVP), alcohol (PVA), acetate (PVAc) and hydroxypropyl methylcellulose (HPMC) were used for dispersion particles in N-methyl-2-pyrrolidone (NMP) slurry, prepared by each characterized. The electrode from large specific developed PVP. By PVP black, additive content reduced one third obtain same performance. Finally, discuss molecular structure performance, force curve between coated tip substrate NMP different investigated using atomic microscope.

The fabrication of very high-aspect ratio 3D carbon microelectrodes for Li-Ion batteries is presented. Using a pyrolysis process under inert conditions, thick layers of patterned SU-8 photoresist (up to 600 μm in height) are converted into carbon. The micro-structures resulting from this process are used as anode for a Li-Ion battery. A detailed explanation on how to create SU-8 structures of a...

Dilithium benzenediacrylate was prepared and investigated as an example of a readily available organic electrode material for lithium-ion batteries. Its poor conductive properties were overcome by a method of carbon-coating in the liquid state, resulting in enhanced cycling performance, displaying a reversible capacity of 180 mA h g(-1).
