About this file
This Statement of Work (SOW) details NASA's requirements for a Battery Leak Detection System to measure leak rates of Li-ion cells for 15-year mission compatibility. The system must test 18650, 21700, and 46120 format cylindrical cell designs, with strict leak rate tolerances of 0.5g for gas and liquid electrolytes over 15 years in vacuum conditions.
Key technical specifications include a test chamber with minimum internal dimensions of 40cm x 21cm x 12cm, leak rate measurement capability as low as 1.05 10-9g/s, 30-minute maximum test time per cell, 110AC/20A VAC power, EtherNet interface, and on-site installation and training at NASA-JSC. The contractor must deliver the instrument within 10 weeks of contract start, provide a 2-year warranty, and maintain a vacuum pump service plan not exceeding 10,000-hour intervals. The solicitation is issued by the National Aeronautics and Space Administration Shared Services Center under solicitation number 80NSSC25911153Q.

Battery Leak Detection System
Statement of Work
18 Jun 2025
1.0 Scope – NASA seek to purchase an instrument that will measure the leak rate of Li-ion cells to determine their compatibility with a 15-year life requirements.
2.0 Free Electrolyte Requirements for Li-ion Cells
2.1 Cell Designs – 18650, 21700, and 46120 format cylindrical cell designs must be leak rate measured.
2.2 Gas electrolyte – 0.5g of difluoroethane over 15 years is the biggest acceptable leak rate that won’t impact cell performance over a 15 year mission life in vacuum conditions.
2.3 Liquid electrolyte – 0.5g of a combination of ethylene carbonate (EC), dimethyl carbonate
(DMC), diethyl carbonate (DEC), and ethyl methyl carbonate (EMC) is the biggest acceptable leak quantity to be compatible over 15 years of mission life in vacuum conditions.
3.0 Contractor Tasks
3.1 Test Chamber – Internal dimensions shall be no smaller than 40cm x 21cm x 12cm to enable fitting a wide variety of cell sizes. This test chamber shall be rigid.
3.2 Leak Rate Measurement – Each cell to be tested for leak rate measurement that could be as low as 1.05 10-9 g/s at ambient pressure each of the molecules and quantities specified in
2.2 and 2.3.
3.3 Leak Rate Measurement Time – Each cell leak rate measurement shall be accomplished in 30 minutes maximum.
3.4 Power – The system shall be power with 110AC outlet capable of 20A VAC.
3.5 Interface – The system will provide an EtherNet interface with 2m cable for connecting to a
NASA PC.
3.6 Training – The contractor shall provide on-site installation & training to NASA-JSC after delivery.
3.7 Maintenance – The system shall require a maintenance plan with vacuum pump service no more frequent than every 10,000 hours.
3.8 Warrantee – The system shall come with 2 year warrantee with proper use.
3.9 Delivery – The instrument shall be delivered to NASA-JSC within 10 weeks after contract start date.
