Energy density was not good.
It could give you that backup, but you still even had a lot more needed to get the same amount of water.
Yeah, exactly.
You couldn't have full depth of discharge cycling, which lithium-ion offers.
Now, in the last seven years, you've had a lot of lithium-ion batteries come in
Because lithium-ion intrinsically has higher energy density, and the old materials that were used on the anode side, so this is a negative electrode inside the lithium-ion battery, it's usually a graphite form.
It's not as safe when you use that over time, over a period of time, charge, discharge, charge, discharge.
So you're normally floating.
Let's say if you want the UPS to function, it should be fully charged all the time and hold that charge.
When the grid fails, that time you discharge for your five minutes or so, right?
Right.
Until the backup generators come on.
So because they're held at that high potential all the time, high potential is not good.
Essentially, the materials inside tend to react more at a higher potential because it has high potential.
Yeah.
It's a bit like, you know, you have a glass and you pour it full and the slightest perturbation drops, spills something, right?
Yeah.
Whereas if it's below, it just shakes inside and it's not spilling outside.
So think about the potential of lithium ions going into the electrode.
That's if it's full.
