Nuckolls, III" Subject: AeroElectric-List: Some new battery chemistries on the horizon? While lithium products are the fair-haired children in the portable energy storage sandbox, there's a couple of interesting technologies being spun-up in the EV world: https://tinyurl.com/yy8cqwbe https://tinyurl.com/y2ptgrjz A follow up on the two articles I cited above . . . Here's a more detailed description of the tab-less construction of the proposed cylindrical cell by Tesla: https://tinyurl.com/y4vv7ozl Some of you may recall a few years back when a start-up in Golden Colorado called Bolder Technologies was rolling out an improved version of SVLA jelly-roll cells. https://tinyurl.com/y42v9ztj We looked at these at B&C. Examples of the 'Start Stick' made appearances at OSH about that time too. Truly amazing performance . . . when they worked. Seems that one, and perhaps the most important process to master was how to achieve good electrical contact with the (-) and (+) plates on each end of the jelly-roll. You had to get hooked up to the entire length of the exposed edges at each end. Failing that, achieving a consistent. 2 milliohm cell resistance was not possible. Degradation of that connection resulted in rapid failure of the cell. The company folded in the US and I think the idea was sold . . . perhaps a couple of times . . . off shore. Haven't hear anything about them lately. Now, it seems that the smart guys at Tesla have a different approach to getting a grip on the edges of foils. This may signal a quantum jump in cell performance. Cells like that would allow folks like AeroVoltz to achieve really BIG cranking currents from their relatively small packages. I recall a conversation with Skip Koss (battery guru par excellence at Concorde) wherein diminutive cells with good cranking might be fabricated into a battery module that would fit right onto the back of a starter motor . . . zero-length fat wires in the cranking circuit. For our purposes, this would allow dual alternator systems to drop distribution wire sizes down to just system loads and take the battery out of the operational power loop. Interesting stuff . . .
