Environmental Cost of Hybrids' Battery Recycling?

LostMyBeaver writes "I have been considering the purchase of an electric or hybrid vehicle for some time. The biggest problem I have currently is that both technologies make use of rechargable batteries. The same tree-huggers telling me gasoline is bad are telling me that batteries are bad too. I'm only partially knowledgable in this area, but it appears the battery technologies are generally based at least on lithium ion, nickel metal hydride, lead acid and nickel-cadmium. I was hoping someone on Slashdot would be knowledgable enough to explain the environmental cost of recycling these batteries. If I understand correctly, after these chemicals are 'spent' so the cells no longer maintain a charge, they are not useful for producing new batteries. I can only imagine that the most common method of recycling the cells is to store the toxic chemicals of the batteries in barrels and refilling the cells with new chemicals. This sounds like an environmental disaster to me. Is there someone here that can help me sleep better at night by explaining what really happens?"

    Stolen from Hybridcars.com:

    How often do hybrid batteries need replacing? Is replacement expensive and disposal an environmental problem?

    The hybrid battery packs are designed to last for the lifetime of the vehicle, somewhere between 150,000 and 200,000 miles, probably a whole lot longer. The warranty covers the batteries for between eight and ten years, depending on the carmaker.

    Battery toxicity is a concern, although today's hybrids use NiMH batteries, not the environmentally problematic rechargeable nickel cadmium. "Nickel metal hydride batteries are benign. They can be fully recycled," says Ron Cogan, editor of the Green Car Journal. Toyota and Honda say that they will recycle dead batteries and that disposal will pose no toxic hazards. Toyota puts a phone number on each battery, and they pay a $200 "bounty" for each battery to help ensure that it will be properly recycled.

    There's no definitive word on replacement costs because they are almost never replaced. According to Toyota, since the Prius first went on sale in 2000, they have not replaced a single battery for wear and tear.

      There are a ton of variables that determine battery life, but to say that it relies mostly on your charger is not true when even the most basic charger these days uses peak detection and thermal monitoring to stop charging.

      NiMH batteries will _always_ get warm when charging at a decent rate (and most cells like to be charged at a rate somewhere between C/2 and C to get reliable peak detection), because charging them is only 70-80% efficient. The rest goes into heat. If you continue pumping current into them after full, then yes, they heat up quickly.

      NiCd batteries only heat up significantly when you continue to charge them after they are full, or you charge them at very high currents.

      The #1 killer of typical batteries is letting them sit around dead or pushing them into reverse voltage by draining a pack too far. They like to be stored with at least some charge in them, but too often they end up sitting around for a year or two in between uses and too often they end up sitting dead which kills them. Lithium based cells are so bad that if you drain them completely, you can not revive them, so they typically have a small circuit on them which monitors cell voltage and disables the cell when too low.

    Caveat - I used to work for Tek Cominco, and have smelted alloys, been a power engineer, and so on.

    First, you have to think of the entire life cycle of both production, shipping, usage, and disposal.

    Production: depending on the battery used (and there are multiple types being looked at), it may be produced from minerals from say Ontario or BC - in which case it was processed using a combination of methods, some of which use hydroelectric power (green). Acids are used in all metal production pretty much, so you pushing a giant truck down the road involves more acid than the batteries for a plug-in-hybrid which quite frankly has less mass. Smelting frequently uses coal, of course, so it depends on the source and composition of the coal - high-sulfur high-pollution like in China or low-sulfur low-pollution like in Canada. It is NEVER no pollution.

    Shipping - again, the parts and batteries will be shipped on a boat using dirty bunker fuel (even in clean ports like LA they only use clean fuel when near the port, a small infinitesimal fraction of fuel usage).

    Operation - if you rarely use a car and it just sits there, then your negative pollution cost of operation for batteries is higher - but your pollution of roadways from diesel/gas would be higher still - if you use it a lot it depends on the power source - if hydro, wind, solar and especially if time-shifted so it charges when power demand is low it has lower impact. If you live in a place where electricity comes from coal it's dirtier.

    Recycling - if it is - and it will, these are expensive batteries - recycled, the cost of mining and production of the batteries is vastly reduced (anywhere from half to one-twentieth the pollution of getting it again). This is why we recycle scrap from cars and cans, it's cheaper than mining the minerals again.

    In general, all things being equal, with typical usage, you will ALWAYS create less pollution with a plug-in-hybrid than with a non-hybrid.

    ALWAYS.

    Don't confuse battery warranty life with operational battery life, by the way.

    No, battery is singular. It may be a collective noun, but that doesn't make it plural, just as fleet is plural, despite the fact that refers to a collection of ships. Hence you can have a battery or several batteries.

  33. Whatever happened to the true economy car? by walterbyrd · · Score: 4, Insightful

    Even after revising the 1985-2007 mpg estimates to make them comparable to the new 2008 mpg estimates, the 1989 Honda CRX-HF is rated at 41 city and 50 highway mpg.

    http://www.fueleconomy.gov/feg/noframes/5263.shtml

    After 20 years of technological innovation, and four years of sky-rocketing fuel costs, shouldn't a new car model get at least 41/50 mpg before that car is considered to be ecologically friendly? Yet greencar.com features the 2008 Nissan Rouge (22 city/27 highway mpg) as a "Top 2008 Fuel Economy Faves." The 2008 Nissan Rouge also has a sticker price of $19,250.

    Seems to me that true economy cars been pulled from the market, and replaces with the new hybrids. Major car manufacturers want us to think that 30+ mpg is something miraculous, and requires an expensive, heavy, complicated, hard-to-maintain, hybrid.

    In my opinion there is more to ecological friendliness than just mpg (although the present line-up fails at even that). Hybrids have huge batteries, and disposing of those batteries is never ecologically friendly. Then there is the ecological impact of manufacturing and shipping these huge, heavy, vehicles. Furthermore, recent road tests carried out by Auto Express show that hybrids often have worse CO2 emissions than standard autos.

    To have a real impact on fuel consumption, and emissions, new vehicles need to be affordable. Hybrids are about the most expensive vehicles on the market. How can hybrids have a positive effect of the environment, if practically nobody can afford the beasts? Even if you can afford the steep sticker price, what about the cost of maintenance? Hybrids have two engines, and use a complicated system to charge their huge batteries. I hate to even think about the cost of maintenance and repair.

    It used to be common that most fuel efficient cars also had the lowest sticker price, and lowest maintenance costs. The cars where simply smaller, lighter, and required more manual operations. With smaller, cheaper, parts, and a less complicated design, the cars were cheaper to maintain. When I bought my 1992 Ford Festiva, the 30/37 mpg rating was the least of my criteria, I was also concerned with sticker price, and maintenance costs.

    Why can't we do as well now, as we did 16 to 35 years ago?

    1973 Honda Civic rated 35/40 mpg
    1986 VW Golf Diesel rated 31/40 mpg *
    1989 Geo Metro rated 43/51 mpg
    1989 Honda CRX-HF rated 41/50 mpg
    1992 Ford Festiva rated 30/37 mpg

    * I got over 50mpg driving from Florida to New Jersey, while running the air conditioner.

  34. Re:"Battery" is plural by Sique · · Score: 4, Interesting

    It actually goes back to the early days of the artillery. A batterie (french, from battre = to fight) consists of two trains of two cannons each together with their teams of loaders, cannoniers and aimers.
