I put white vinegar on the areas where the NiCad juice turned the PCB green, and it didn’t seem to do anything. So after awhile I washed it off with plain tapwater. I used a soft brush and a lot of the green coating washed off. It’s not in very good shape. I’m wondering if

North America just got a new recycled Li-ion battery materials plant
This is great! But it’s just a start – we need much, much more storage deployment as soon as possible. US battery storage smashes deployment records in Q4 2023
This article gives good explanations of how batteries are made and what advantages and disadvantages they have. The top three battery chemistries coming soon to EVs – and none of them are solid-state
This article is mostly about Plug Power, which they call a startup. They talk about the the BIL – Bipartisan Infrastructure Law and its funding incentives. US Green Hydrogen Industry Kicks Into High Gear, Politics Or Not https://cleantechnica.com/2024/03/15/us-green-hydrogen-industry-kicks-into-high-gear-politics-or-not/
A YouTube short of how lithium batteries are recycled.
By this 2024 summer even lower battery prices. Battery prices collapsing, grid-tied energy storage expanding
I built this “tungsten roadwork beacon” as Clive calls it, using the parts given in my schematic (photo below). I didn’t have a 6V, 90 mA lamp, so I simulated it by using three 20 ohm, 1/4 Watt resistors in series, which gives 60 ohms and 100 mA load with 6VDC. For an indicator I

The graph shows the battery prices fell substantially since last year. “”So EVs will be cheaper than ICEVs in 2025…””
The battery is the most expensive piece of an EV, so lower costs will reduce the COGS – cost of goods sold, thus the consumer will be able to get an EV for even less. This makes the EVs more competitive with gas guzzlers. It will also make the $25,000 EV easier to build. CATL,
