High Temperature Batteries Joint Industry Project: Scope of Work

JIP-Sandia Statement of Work
Dec 3, 2007

This effort will reduce the risk associated with deep reservoir drilling and future aircraft secondary power systems by aiding in the commercial development of high-temperature batteries. This effort will work with emerging battery technologies (lithium ion, molten sodium-sulfur or other) to identify industry requirements and provide applicable testing.

Technical Content:

  1. Sandia will work with the JIP members to develop a basic set of battery requirements and marketing information to provide to potential battery manufacturers.

  2. Sandia will work to identify potential lithium ion (or other battery technologies) battery manufacturers to meet low temperature (room temp to 150C) operating ranges. These potential battery manufacturers will be provided the basic set of battery requirements generated by the JIP and asked to work with the JIP to develop a commercially available battery to meet those requirements.
    1. Depending on funding availability and number of potential battery technologies, Sandia will undertake testing of battery cells to meet the basic set of battery requirements.

  3. Sandia will provide the following testing of the Sodium Sulfur batteries from ESI as defined in item 4 below:
    1. Sandia test results will belong to sponsors members.
    2. Sandia will hold biannual � day sponsors member meetings.

  4. Testing Sodium Sulfur batteries from Electrochemical Systems.
    1. Vibration testing of a dummy cell from Electrochemical Systems. Testing will be conducted at Sandia for all three axis.
    2. Life cycle (charge, discharge and internal impedance) testing of complete functional prototype batteries @ 150 and 225�C. Fifty cycles of charge & discharge of prototypes at each temperature. Charge and discharge rates to be determined.
    3. Low temperature, 125�C and below, IR and voltage curves will be measured and reported on.
    4. Leakage current (or self discharge) testing. These will be 2000 hr tests at 150 & 225�C following the fifty cycle charge and discharge tests. Fully charged test cells will then sit in an open circuit state at temperature for 2000 hrs. Following the 2000 hrs test, the cells will be discharged to measure any loss of stored energy.


  1. A basic set of battery requirements and basic market information for use in encouraging continued commercial development of high-temperature batteries best meeting the needs of the JIP members following signature of the SAE contract.
  2. Sandia will provide the sponsor with all test results as data is collected with approximately 16 weeks required from completion of testing.
  3. Sandia will provide a list of potential lithium ion battery manufacturers for the JIP members by July 2008.
    1. Invite each potential manufacturer to work with the JIP to develop a room temp. to 150�C secondary battery
    2. Participate in manufacturer testing of their battery technology to meet the basic battery testing requirements.
  4. Sandia will discuss with the JIP to include testing of other potential high-temperature batteries which may be developed.
