Sulfates: Worse for batteries than they are for hair!
Motor Trend|October 2022
Many of us fret about sulfates in shampoo and sulfites in wine, but I just learned about the awful effect of employing sulfates in battery cathode production.
Sulfates: Worse for batteries than they are for hair!

Apparently, the way most lithium-ion cathodes have been made for 30 years results in a colossal amount of waste. Fortunately, I learned about this problem while discovering a potential solution.

The cathode is a battery's positive electrode, where charging energy is applied. In most of today's lithium-ion batteries, these are made of lithium-nickel manganese-cobalt (NMC). The way these have been made involves mining the metals, turning them into metal sulfates or salts, converting lithium carbonate to lithium hydroxide, then transporting these materials to the cathode manufacturer where they're mixed in water. A caustic material like sodium hydroxide gets added to precipitate out a powder precursor that gets mixed with the lithium hydroxide and baked in a furnace to form grains of lithiated cathode material. A special coating is then applied in a separate process.

2023 Ford F-Series Super Duty

The heavy-duty truck world moves more slowly than other pickup classes, and progress comes in spurts. Take the Ford F-Series Super Duty, whose recent refresh included softer-edged styling, a new entry-level gas-fed V-8, a new high-output 6.7-liter turbodiesel V-8, and myriad small improvements like new bedside steps. Is it still basically the same truck as before? Absolutely, but it’s also a better Super Duty, however incrementally.
