Lithium Ion Batteries are one of the more promising battery technologies. Ovonics is the leading producer of Lithium Ion Batteries. Their batteries offer electric cars a 180 mile per charge range. However, Ovonics focuses on the hybrid battery market at the moment.

Ovonics was purchased by Chevron-Texaco in 2001, reportedly so Chevron-Texaco could expand their business into the emerging hybrid market. But, some in the alternative energy field see an ulterior motive, so Chevron-Texaco can suppress the development of Lithium Ion Batteries. They may have a point, as Ovonics has shown little interest in selling Lithium Ion Batteries to electric vehicle enthusiasts since purchasing the company.

Recently, Toshiba announced a breakthrough in Lithium Ion Battery technology (see story below) that promises much faster recharge times (1 minute for 80% recharge) and denser power densisities. If this announcement lives up to their claims, a 200+ miles per charge car battery is likely, and it also opens up the possibility of convient recharge stations, as the battery recharges within minutes. A breakthrough that would allow serious consideration towards building an electric car infrastructure.

A derivative of the Lithium Ion Battery is the Lithium Sulphur Battery, which could potentially deliver a 300+ miles per charge car batteries for electric vehicles. Lithium Sulphur Battery technology is being developed by many companies, including Sion Power.


Altairnano Tests Confirm Extended Battery Life

Altairnano battery cells complete 15,000 charge/recharge cycles with minimal loss of charge capacity

RENO, NV -- October 26, 2006 -- Altair Nanotechnologies Inc.,a leading provider of advanced nanomaterials for use in energy, automotive, life sciences and industrial applications, announced today that, in ongoing testing, it has completed 15,000 deep charge/discharge cycles of its innovative NanoSafe battery cells. Even after 15,000 cycles the cells still retained over 85% of their original charge capacity. This represents a significant improvement over conventional, commercially available rechargeable battery technologies such as lithium ion, nickel metal hydride and nickel cadmium. These other commercially available rechargeable batteries typically retain that level of charge capacity only through approximately 1,000 deep charge/discharge cycles.

The battery cells were tested in Altairnano's labs at 10C (6 minute) charge and discharge rates. They were deep charged and discharged meaning they were taken to 100% charge and 0% charge respectively during the 6-minute cycles. Although tests involved full charges and discharges, partial charging and discharging of the battery does not appear to impact the life or the holding charge capacity of the batteries i.e. they exhibit no memory loss.

In theory, a 15,000 charge cycle life would translate into a battery that would last greater than 40 years if it was charged daily, as would be the case in an electric vehicle or plug-in hybrid electric vehicle environment. However, in practice, other wear and tear factors would realistically limit the actual life of the batteries to probably 20 years.

"These results represent a remarkable achievement by our battery development group. We believe that the commercial implications of such an extended life battery are significant and would seem to provide us with an as yet unmatched competitive advantage in the electric vehicle and plug-in hybrid electric vehicle markets, and potentially other markets," said Altairnano President and CEO Alan J. Gotcher Ph.D.

Toshiba 1-Minute Recharge Lithium Ion Battery

New battery offers unsurpassed recharge performance and high energy density

TOKYO -- Toshiba Corporation today announced a breakthrough in lithium-ion batteries that makes long recharge times a thing of the past. The company's new battery can recharge 80% of a battery's energy capacity in only one minute, approximately 60 times faster than the typical lithium-ion batteries in wide use today, and combines this fast recharge time with performance-boosting improvements in energy density.

The new battery fuses Toshiba's latest advances in nano-material technology for the electric devices sector with cumulative know-how in manufacturing lithium-ion battery cells. A breakthrough technology applied to the negative electrode uses new nano-particles to prevent organic liquid electrolytes from reducing during battery recharging. The nano-particles quickly absorb and store vast amount of lithium ions, without causing any deterioration in the electrode.

Toshiba just had their first recall. (Aug. 2007)

Valence Technologies' Saphion Batteries: Safety First

An article in Wired, "Driving Green, Explosion Free" by Matthew Shechmeister explains combustibility problem of volatile cobalt-oxide in many if not most lithium ion batteries. If you fire a bullet into one, a huge explosion results, but if you discharge a firearm into a Texas-based Valence Technology's phosphate-based battery (nothing happens. This makes the Saphion inherently safer for large formats, especially automobiles. The drawback that the phosphate-based battery has somewhat less storage capacity than nickel metal hydride may be offset by the greater safety, especially in vehicles where there is risk of collision, exposure to gasoline fire, punctures, and other hazards. The higher introductory cost of the Saphion is expected to be offset by increased production volume. Please see [,1282,68631,00.html.

Automotive Industries in February 2005 reported that the Saphion had begun to make an appearance in GM concept cars such as the Sequel fuel-cell crossover SUV. There's also a later-stage benefit. While the cobalt oxide and nickel batteries require special end-of-life disposal, the phosphate Saphion batteries are approved for landfill disposal in the state of Nevada due to not being classified as toxic metals. This source also reports that Alternativ Canada, which retrofits and converts vehicles, has more than doubled the single-charge range of one of its Hyundai Accents by replacing the lead-acid battery with a Valence U-Charge phosphate battery.

The same article reports that Segway replaced NiMH and NiCD batteries in its Human Transporter with Saphion batteries, doubling the operating time from four to eight hours. This allows full-day operation, and increases commercial-use prospects for Segway's product. Please see:

In the News

Battery Breakthrough -- As President Bush talks up the need for more research, scientists are making advances in hybrids and all-electric vehicles. - Researchers have long known that a material based on lithium, nickel, and manganese could be used to make lithium-ion batteries that store large amounts of energy. The problem has been that batteries based on this material could be charged and discharged only slowly, otherwise the amount of energy they could store would drop dramatically. MIT created a computer model that showed that when it was under conditions of high power, disorder in the lithium-nickel-manganese material caused it to compress and trap the lithium ions that allow electricity to flow. The researchers then synthesized a version of this material without this disorder, freeing the ions to move quickly. (Technology Review February 22, 2006)


Lithium Ion Battery Fires

Laptop Battery Fire - "We intentionally created conditions in which the Li-ON battery pack would explode inside a generic portable. The results are dramatic. There are numerous conditions where these fires can occur in real life. Faulty battery packs (driving the recalls), faulty protection circuits inside the PC, exposure to excessive heat, and blunt force are some of the major ways that this could happen to you." (PC Pitstop / YouTube Nov. 9, 2006)

On Aug. 10, 2007, New Energy Congress member, Congress:Member:Ken Rasmussen wrote the following regarding the above video:

This is an extremely serious matter as we now see the otherwise excellent Tesla Car will have the equivalent of what, 50 to a hundred laptop batteries on board? If a drunk rock star flies that thing into a gasoline vehicle that just starts a small fire, the large lithium battery fire could destroy a neighborhood. They couldn't read the temperature of the flame in the video, just that it was over 1,000 degrees F. Paul Pantone told me once, and I believe him on this, that fires over 4,000 degrees F excite steam to the point that it instantly breaks down into component gases, creating an even more violent explosion. 

Congress:Former Member:Mark Anthony Dansie and I were discussing this in reference to Tesla Motors just the other day. I don't think the new ceramic, Eestor or ultra capacitor designs have this problem.
