If I only had a dollar for every promising battery technology that never made it to market.

They have been talking about breakthroughs in Li-Ion batteries for years, but I am not sure that the batteries that make it to consumers have improved even incrementally in the last ten years. The quality control seems to have gone more in the wrong direction.

The figure, along with much of the article is undecipherable. Note also that the heralded energy density value “above 360 mA h g-1” in the “ultrahigh power and energy density” of these batteries Is much-much less than the 13,000 “mA h g-1” energy density of gasoline. The fuel load of these batteries would weigh 36 times the weight of the same energy in gasoline.

Does this make them explode better?

In light of the rapid growth in the use of lithium-ion batteries, researchers worldwide have been trying to identify materials that could increase their efficiency and performance. Ideally, these materials should contain elements that are abundant on the planet and have a high energy density.

Is that because we allowed the Chinese to corner the markets on rare earth elements?

“Cation overstoichiometry and the resulting partial order is used to eliminate the phase transitions typical of ordered spinels and enable a larger practical capacity, while lithium excess is synergistically used with fluorine substitution to create a high lithium mobility.”

That’s what I was thinking, too!

Just think of the fires these babies could cause!

Wa-hoo!

“Mechanical alloying (MA) is usually a dry, high-energy milling process that has been employed to manufacture a variety of commercially advanced materials. ... The process consists of repeated welding-fracturing-welding of a mixture of powder particles in a high-energy ball mill.”
