Abstract

Processes for applying magnetic fields to articles such as a layer or layer-coated articles, and more particularly to coatings having graphite particles, preferably for manufacture of negative electrodes having aligned graphite particles, for example for fast-charging lithium-ion batteries. The application of magnetic fields may be continuous. For this, magnetic tools with permanent magnets may be used for applying magnetic fields, wherein an article is moved relative to a magnetic tool. Application of magnetic field is made before the initiation of a drying phase and/or during a drying phase.
