What the technology looks like in the lab

Three recordings. The first is a complete charge and discharge cycle filmed in one unbroken take. The second is a shorter charging session, also uncut. The third explains the pulse mode we use, in animation.

The complete measurement, start to finish, in one unbroken shot

This is the long version, and it exists to answer one question: was anything edited out. The camera runs from the moment the instruments are laid out until the last reading is written down. Nothing is trimmed, sped up or reassembled.

The cell is a standard off-the-shelf Samsung INR18650-25R, identified on camera at the end of the recording along with its datasheet. Its measured capacity in this session is 1.5 Ah. It is first run down on an electronic key, then charged, then discharged again into an electronic load, so the charge that goes in is measured coming back out on the same bench, with the same instruments, in the same session.

A standard cell charged from empty to full in 12 min 40 s

A standard off-the-shelf 10 Ah LiFePO4 cell, 3.2 V nominal. The meter starts at 3.106 V, below 5 per cent state of charge. The stopwatch is stopped at 12 min 40 s with the cell at 3.674 V under charge; once the current is removed it settles at 3.436 V, full charge. Every reading is on screen throughout: nothing is cut, sped up or reconstructed.

The cell is not modified in any way, and no active cooling is used. Temperature is monitored throughout.

Animation · how the charging mode works

Pulse charging mode, explained

Short high-current pulses are followed by pauses. During a pause, charge carriers keep moving inside the cell, and part of the energy continues to be stored after the pulse itself has ended.

This is our working picture of the process, drawn to make the charging mode easy to follow. It is a model, not a proof.

On the mechanism. The measurements are reported exactly as recorded. The physical and chemical model behind them is what we are building now, together with Bar-Ilan University and Prof. Eran Rabani of the Hebrew University of Jerusalem. We are experimentalists: the result is reproducible in our lab, and the explanation is the work ahead. That model is also what will let us optimise the charger itself and make the results predictable rather than empirical.
