ISS Lithium-Ion Battery Impact Test
This test was undertaken for the International Space Station program in support of the selection process for replacing the nickel-hydrogen batteries that were originally implemented on the ISS. The test was performed to compare the reaction of a direct MMOD impact on different Li-Ion battery designs. These batteries provide power to various systems on the space station during orbital night, a period of 45 minutes when the ISS is in darkness. This test was designed to observe the batteries reaction to an impact that penetrates the surrounding protective shielding. Testing was performed in a partial vacuum to simulate on-orbit conditions.

Successful impacts on the test article are extensively photographed to record resulting damage and to supplement post-test analysis. The following images are from the ISS Lithium-Ion battery hypervelocity impact test. This test helped characterize the damage to a Li-Ion battery resulting from a direct impact and will help in understanding how a direct MMOD hit to a battery may affect the ISS.
