Please find this simple reply regards what’s going on in a 2v cell at the active lead DIOXIDE level for the IFLA and PLante cells.
This will form, after re-editing etc, part of my ‘How to Make a modern Plante 2v 450ah lead acid battery’ book.
I always try to write and explain and show with picks what’s practically going on. I have concerns that some groups are guessing and starting to spout rubbish about the humble 2v lead acid cell, so hopefully my below comments will straighten a few folks out.
........... Each 2v volt cell has a charge and discharge rate and this depends on several factors.
1. The structure of the matrix grid plates and the ratio between the supporting lead that is a basic PLANTE forming, and the composition of the LEAD DIOXIDE that is already made and pasted into the lead matrix that gives a higher Amp Hour holding capacity from the word go.
2. It is very important to recharge and reform the lead oxide at a suitable rate. Eg, like electroplating, to quick and the plating does not form and adhere well. The same with lead dioxide, make it efficient and give good ah output, then its short lived. Make the dioxide paste longer lasting but less preforming ah output, and more stable, then welcome to the IFLA as the lead plate matrix is very, very thick and holds the Oxide paste firmly.
BUT excessive constant charge on a individual 2v cell and the lead oxide that is pasted into the grid matrix will be disrupted, especially where it rests in the lead matrix grid, and then the precious lead oxide paste will shed and drop out.
3. With the IFLA batteries the lead matrix grid plates hold the lead dioxide tight, but the lead dioxide is fragile. The lead holding grid it self will also form the correct dioxide over many (over 40) charge recharges, and slowly integrate with the dioxide pastes. BUT CONSTANTLY GETTING THE CHARGE RATE WRONG AND THE PŔECIOUS LEAD DIOXIDE PASTE WILL START SHEDDING as the bond will be broken.
IN CONCLUSION. Some of you are aware of my R&D experiments and builds on a new modern form of the old pure lead PLANTE lead acid 2v 450ah battery. Forming the pure lead sheet surface into a active lead dioxide mush, but making this surface dioxide mush stable and yet giving good AH output rates, is mind boggling, as the variables that require experimentation and calculation are vast.
Oh yea, and these 13 plate 2v PLANTE cells of mine are all designed around a DIY context and constructed with simple tools.
So bear with me guys as i examine and publish a useful definitive practical guide to the humble 2v lead acid cell.
