Battery Decomposition Early Warning

An early-warning sensing concept intended to detect precursors to lithium battery decomposition and thermal events.

Battery Decomposition Early Warning

Thermal runaway is a late, destructive event. The more useful question is whether chemical or thermal precursors can be detected early enough to change the outcome.

What I built or investigated

This research concept explores gas, thermal, and signal-pattern sensing for early warning of lithium-battery decomposition before a full thermal event. The concept shares the broader Sentinel embedded research platform, while its sensor selection and evidence requirements remain specific to battery decomposition.

The work did not happen in one jump.

  1. 01

    Compared the concept with other grant directions and selected it as a stronger fit for a broader engineering research pathway.

  2. 02

    Separated precursor detection from conventional smoke or temperature alarm behavior.

  3. 03

    Outlined sensor fusion and signal-processing needs instead of assuming one threshold sensor would be sufficient.

Where the project landed

A focused research direction with the next step being controlled decomposition data and sensor-selection experiments.

What carried forward

  • Early-warning claims require carefully defined lead time and false-positive testing.
  • A compelling hazard does not automatically create a valid sensor; the measurable precursor must be proven.
