Replying to: gagrice (Nov 11, 2007 1:09 pm) No, it means the cost of one of the raw materials used is 50% higher for the manufacturer. There is a lot more to the cost of making a battery (and most things) than just the cost of raw materials and there are also things other than manufacturing costs that are involved in determining the market price for a product.

Replying to: jeffyscott (Nov 11, 2007 1:33 pm) Whittingham notes that although the titanium sulfide battery was technologically sound, it wasn't a commercial success. Success with lithium-ion batteries came some 15 years later when Sony introduced a battery that incorporated a lithium cobalt oxide (LiCoO2) cathode and a lithium-intercalated carbon (LiC6) anode. The cobalt-based battery was a hit with portable electronics applications because of its ability to store a lot of energy in a small, lightweight package. PS I think with all the downsides to Li-Ion we should be looking at other technologies. I think Caterpillar has hit on just such a possibility.

Replying to: gagrice (Nov 11, 2007 1:47 pm) The most common EV lithium battery is LiFePO4, without cobalt. This type of battery is also safer and longer lived than the LiCoO2 cell (it doesn't explode, either.) Materials costs are rising because of the falling dollar. Any materials that can be locally mined will have an advantage. |

The Xebra becomes the first four-door electric car to be approved for street use in the UK. Check the Alternate Route's take on being Street Legal |

Replying to: gagrice (Nov 12, 2007 6:25 pm) Enerdel's battery technology is similar to Altairnano's, no Cobalt or risk of thermal runaway. They also claim that the price of these battery packs will be low enough to allow for drivers to recoup the initial price premium of an EV within 2 years. We'll see but it sounds pretty good.

Replying to: tpe (Nov 20, 2007 5:29 am) Let's hope so, but that statement in itself is pretty vague. Do they give what they based that statement on? I looked at the company. Tiny little thing...perhaps..perhaps.

Replying to: reddroverr (Nov 25, 2007 2:37 pm) "Lithium ion batteries developed by the German company called Li-Tec, which is taking part in a development program with Bosch, "take up 30% less volume than those from Toyota" and "allow you to go three times further for the same weight than French models, " according to Li -Tec director Tim Schaefer. Li-Tec’s ‘Separion’ system consists of two lithium electrodes in an electrolyte, separated by a flexible ceramic membrane that reportedly provides greater thermal stability than has so far been achieved in lithium ion batteries. Their tendency to overheat is what led Toyota to delay installing li-ion batteries in the forthcoming third-generation Prius hybrid. Other consortia besides Bosch are also developing lithium ion battery technologies focused on thermal control." http://puregreencars.com/Green-Cars-News/Technology/Li-Tec-Reports-Lithium-Ion-B- attery-Breakthrough.html

Replying to: reddroverr (Dec 12, 2007 1:07 pm) toshiba Not a lot of specifics in this article other than a 5 minute recharge time and 10 year lifespan. The field of companies conducting R&D on advancing battery technology is definitely getting crowded. |
