just another reason to favor LiFePO4 which does not. The mining of Lithium is far less environmentally damaging than the mining of tarsands for oil. There is no industrial use of nature which does not have negative effects. Choose your poison wisely.[url=http://www.fool.com/investing/general/2014/01/19/tesla-motors-dirty-little-secret-is-a-major-proble.aspx said:the article[/url]"]In other words, li-ion batteries that contain nickel and cobalt have a significant effect on health and the environment. More specifically, this includes Panasonic's automotive grade li-ion batteries, which contain lithium, nickel, cobalt , and aluminum, and a proprietary cathode geometry developed jointly by Panasonic and Tesla -- and are currently used in the Model S.

I suggest no more than 1 kid per couple, if you really care about the bubble we live in. I'm not talking about eliminating people or restricting birth. I mean making personal decisions that have a lasting effect on the the world we live in.

The environmental impact doesn't come from the cell mfg process. It's dialed in to have zero dangerous waste materials, and every process involves solvent uses capture/reclamation in vacuum dryer ovens. The cathode/anode slurry dispersion solvents are reclaimed and re-distilled to purify it and is re-used in a closed loop system. The whole process is contained in a humidity and temperature controlled clean-room type facility. You take in dry metal oxide powder ingredients and some drums of extremely high purity solvents, and rolls of copper and aluminum foil and laminated plastic aluminum foils (or little stamped metal cans), and some electricity (and it's not nearly as much energy as people think, the process has no high-energy steps involved), and you end up with pouches or can's as the output of the factory, along with the die-cutting scrap and things which goes straight back to the foil MFG's for recycling.
The concept that mining Lithium is some big environmental impact, or even that Lithium is a substantial cost or component of Lithium ion batteries is a puzzle to me. Making Lithium carbonate is mainly done with direct solar heating in big troughs dug with bull dozers, and stirred occasionally as the brine dries. Most mined Lithium is used in ceramic glazes and colored glass and things rather than batteries.
There is far more Nickel used as alloying agents in the high performance steel alloys in an ICE's crankshaft and con rods and valves etc than is used in a Tesla battery.
With respect to cobalt, yes it sucks that it performs so damn well in a battery yet is a PITA to mine and hence is costly and has some environmental impact. Possibly similar environmental impact in mining and extracting and processing the couple pounds of Cobalt in a Tesla pack as a gas car burning a couple tanks of fuel (though not nearly as much energy wasted as burning the couple tanks of fuel).
There was a time early in the infancy of LIB construction when there were no solvent reclamation and cobalt oxides were a high percentage of the cell weight (now it's just a small fraction, but soon none will be used at all), and the processes were crude and dirty. Thankfully, it's simply not efficient or cost effective to make them that way anymore, and modern LIB's construction is very low environmental impact.
Hillhater said:Whilst i too am very skeptical as to the accuracy and motivation behind this data, you cannot deny or ignor the environmental impact of battery production.
True and accurate detailed "life cycle" data collection is a near impossible science, which by definition leaves it wide open to distortion by various "quasi authoritative" parties.
...much like the climate debate, ..selective data presentation.

How did you get a tour of tier one cell plants? How do *I* get a tour of tier one cell plants? The description you gave here about the way that they create a closed loop in the manufacturing process is interesting and I would like to know more.

It's closed loop in a proper LIB mfg by necessity. It's really expensive and wasteful to constantly be drying air to -60degC dew-point or lower to ensure you've condensed out all the available humidity, or do inert gas purged production lines etc, but you can NOT accept humidity in the cells or they are doomed to be puffers even just sitting on the shelf. This means closed loop environmental control is already present on these stages of the battery line, and to have a solvent vapor trap it only takes a cold-finger condenser in the air circulation path (followed by a heater) and you can control the vapor concentration to both improve drying rates and reclaim solvent. I don't know how the process for cleaning the solvent works after it's collected, but they seem to have it dialed.

Man I have some oil field guys still on FB as "friends" from back when I lived in northern Alberta. I can't believe how out of touch they are. And I think its partially their own ignorance along with the circle jerk of people they associate with that keep the false propaganda machine going. But I am constantly battling these guys. For instance one guy posted all of this in the last week. The one with Charlie from the Chocolate factory I usually respond with some specs and a Link to Rimac or Tesla and then as the convo goes I use Zero info and keep going and no matter what I debunk all the myths but then they basically say the size of their penis wont allow them to ride/drive anything green even when I point out I don't doo it because its green I doo it because its better.liveforphysics said:Arlo1 said:Its to bad to many people in the world believe this shit!
Yes it is Arlo. :-(
I don't know what is up with the recent anti-EV propaganda. I suppose it's a good sign gas is aware if it's pending inevitable obsolescence, but just lame to see the disinformation campaign BS.
