Power from the barrel of a gun

Australian Prime Minister Anthony Albanese's immediate reaction to the assassination attempt on US presidential candidate Donald Trump was that there was 'no place for violence in the democratic process', but this is the latest in a very long line of incidents which prove otherwise.

I think it’s really stupid and potentially dangerous that the concept of an absorption period of charging a lead acid battery has been transferred across to charging of lithium batteries.

Lithium batteries don’t need an absorption period, and in fact the absorption period, with its raised voltage, is likely to overfill the negative electrode with lithium ions. This overfilling can create cracks in the crystal structure of the electrode which will decrease the battery’s lifespan.

On top of that, in extreme circumstances the absorption period can risk the formation of dendrites that can cause a short circuit. Fortunately, lithium iron phosphate batteries have a significantly higher ignition temperature than other lithium-ion batteries. That’s probably why we haven’t been having too many problems.

In my opinion the absorption voltage provided by charge controllers should be reset at the same voltage as the resting voltage (54.4V for a 16 cell LiFePO4 ‘48V’ battery; 13.6V for ‘12V’; 27.2V for ‘24V’.)

It’s just teething problems for new energy.
