Why Lead-Carbon Batteries Will Deflate the Li-ion Bubble - vrla batteries

I have been reminding readers for more than a year, although lithium
The ion battery is charming, fashionable and sexy;
They will face great challenges from leadership.
It's a bit bulky but offers a competitive carbon battery for circulation-
A small part of the cost is life and power.
To appease the gospel evangelists of lithium fundamentalists and electric vehicles, I would like to make it clear earlier
Carbon batteries may not be the first choice for plugsin vehicles.
Nevertheless, it is clear that lead
Carbon batteries will be the only smart option for micro, light and all hybrid electric vehicles [HEVs]
And many grid-connected energy storage applications.
An article by Earth2Tech dated July 30 titled "Why is Vinod Khosla lithium-
It all says, "the most important thing to remember is economic gravity-the cheapest thing will win in the end.
"What do you know?
People smarter than me believe it's cheaper than cool.
As the average reader knows, I recently attended Infocast's storage Week 2009 and served in three discussion groups.
The core data for this article comes from a slide
Show me Patrick T.
Dr. Mosley, senior leadership chairman-
Acid battery AllianceALABC]
Published at the meeting.
Although I know that the combination of advanced carbon materials and traditional lead has brought amazing benefits.
Over the years, the Moseley demo was one of the first public documents to explore the details. A copy of Dr.
Here is a demo of Moseley's storage week.
The full archive of my article in the field of energy storage can be found here.
The media began to focus on leadership-
When Autobloggreen reported using split-January 2008-electrode lead-

The main point of the report is to exchange 17 kg of the heavy penalty (37 pounds)

Moseley's presentation further advanced the Autobloggreen report and provided the following ALABC charts
Sponsored cycle life test, the Super Battery and the standard NiMH battery were cycled 180,000 times at a discharge rate of up to 5C and a charge rate of up to 4.

This series of specific tests compares the duty cycle developed by two battery strings at a discharge rate of up to 4C and a charge rate of up to 3C using BAE Systems for its hybrid transport bus project.

The harvest of life is extraordinary.
However, the real meat and potatoes demonstrated by Moseley are a slide show that combines the performance and price of the Super Battery (

While I don't like to look at the obvious things, a simple battery technology exceeds USABC's goal at a comfortable price, while reducing the label price of a mild hybrid by 10%, this is important in difficult times as most of the US and Europe measure the real value of car purchase decisions and requirements.
More importantly,
Carbon batteries can be manufactured in existing plants without the need to build new manufacturing, supply chain and distribution infrastructure from scratch.
As a simple question of capital efficiency,
The manufacture of carbon batteries will be one order of magnitude cheaper.
It can also increase to the required amount in a few years rather than decades.
In a January 2009 article entitled "lead-

I also reprinted Sandia's summary slide, which concluded, "the new carbon-enhanced negative poles in VRLA batteries have greatly improved the utility PSOC cycle --
10 times the life. "In a follow-

Any technical improvement in performance is highly disruptive.
Leading Facts
Carbon batteries can use cheap and rich raw materials from domestic sources to complete the work and provide a product that is easy to recycle in existing facilities, which changes the rules of the game;
Especially when lithium
Ion and NiMH batteries are based on imported raw materials that may face significant shortages
Supply is restricted and new recycling technologies and new recycling infrastructure need to be developed.
In America, we get up in the morning, we go to work, we solve our problems.
NiMH and lithium-
Ion batteries cannot help the automotive industry to meet EU standards for accelerating emissions of carbon dioxide from exhaust gas and us cafe standards because the factories that make the batteries do not exist, even if they exist, mines in the world are not able to extract the required raw materials quickly enough to meet the demand.
In the next ten years, lithium-

It's time to stop talking about the distant future and focus on solving today's problems.
