At present, the conductive agent for domestic lithium-ion batteries is still mainly conventional conductive agent SP. Carbon black has better ionic and electronic conductivity. Because carbon black has a larger specific surface area, it is conducive to the adsorption of electrolytes and improves ionic conductivity;
Ketjen black only requires a very low amount of addition to achieve high conductivity, so Ketjen black has always been the best among conductive carbon blacks and has been in a leading position in the market for a long time.
