Controlling lithium deposition during manufacture of a battery

摘要

The present subject matter provides apparatus and methods for controlling lithium deposition during manufacture of implantable medical device batteries. A method includes processing materials to form the battery and performing a discharge conditioning process step. The discharge conditioning process step includes using a reduced discharge load and applying a discharge load intermittently to decrease formation of lithium deposits on negatively charged surfaces within the battery.

主权项

1. A method of manufacturing a lithium battery for an implantable device, the method comprising:
decreasing the formation of lithium deposits, wherein decreasing the formation of lithium deposits includes conditioning the battery during manufacture using a controlled rate of discharge and load current, wherein conditioning the battery includes controlling the rate of discharge of the battery to be the rate of discharge the battery takes to discharge in one hour.
