Abstract: An implantable medical device, such as an implantable pulse generator (IPG) used with a spinal cord stimulation (SCS) system, includes a rechargeable lithium-ion battery having an anode electrode with a substrate made substantially from titanium. Such battery construction allows the rechargeable battery to be discharged down to zero volts without damage to the battery. The implantable medical device includes battery charging and protection circuitry that controls the charging of the battery so as to assure its reliable and safe operation. A multi-rate charge algorithm is employed that minimizes charging time while ensuring the battery cell is safely charged. Slow charging occurs at lower battery voltages (e.g., battery voltage below about 2.5 V), and fast charging occurs when the battery voltage has reached a safe level (e.g., above about 2.5 V). When potentially less-than-safe very low voltages are encountered (e.g., less than 2.
