BATTERY MANUFACTURE

摘要

Applying materials, e.g. electrolytes and other materials, in the form of a spray during battery manufacture, particularly using a vibrator nebulizer (4) to produce a small droplet, low velocity spray. Preferably the droplet size is about 5 micron to about 30 micron and the spray velocity is about 10 inch/sec or less, particularly about 3 to about 5 inch/sec. The method includes providing a separator and applying the electrolyte to at least one portion of the separator; providing the separator in a battery can prior to the applying the material by spraying; applying the electrolyte such that substantial pooling of the electrolyte in the bottom of the can is provided.
