摘要
In recent years, the critical need for better performance, higher safety, and longer cycle life in lithium-ion batteries has become so tangible and ubiquitous that an increasing amount of effort has been focused on the search for new materials. However, in contrast to the search for advanced and efficient materials, electrode engineering is a practical way to enhance battery performance. Here, we show that the electrochemical per-formance of the NMC811 electrode containing functionalized powder (Carbon Black KS6) can be remarkably enhanced by fabricating cathodes with an out-of-plane aligned architecture. The aligned architecture results in faster charge transport kinetics and a specific charge up to two times higher than that of non-architectured electrodes at a rate of 5C.
