Which synchrotron radiation techniques are used in battery research?

Herein, the three most wide and important synchrotron radiation techniques used in battery research were systematically reviewed, namely X-ray absorption fine structure (XAFS) spectroscopy, small-angle X-ray scattering (SAXS), and X-ray diffraction (XRD).

How does a battery test work?

The battery pack being tested will be fully charged in advance to simulate the most severe thermal runaway scenario, ensuring that the battery has maximum energy during testing. The specific method involves charging to 4.2 V with constant current and voltage, and calibrating it to 100% state of charge (SOC).

How to test a redesigned battery for thermal runaway?

Assemble the redesigned battery into a module for thermal runaway testing. It can be seen from the figure that under the influence of the high temperature of the heating wire, the thermal runaway of the target battery caused a chain reaction of Thermal runaway of the two batteries around the module.

Can reductive gas manipulation reduce the thermal runaway of lithium ion batteries?
