BMW i3 uses batteries with silicon in the anode

The Race For Silicon Anodes

Graphite is the most widely used material for battery anodes.  The anode is the positively charged electron collector in a battery.  It collects and accelerates the electronics emitted by the battery’s cathode.  Graphite gets the anode job because it is has excellent electric conductivity and resists heat and corrosion.  Plus it is light weight, soft and malleable. As satisfied as manufacturers might be with graphite anodes, none would balk at an alternative material that boosts battery performance or reduces cost.  Scientists believe battery capacity can be increased as much as ten times by using silicon for anodes.  It requires six atoms of carbon to bind one...

Yankee Graphite

Several graphite developers have made plans to integrate forward into the hottest segment of the market  -  battery-grade graphite.  According to Industrial Minerals, spherical graphite suitable for lithium ion battery anodes is priced in a range of $2,700 to $2,800 per metric ton in China where many battery manufacturers are located.  This compares quite well to the range of about $655 to $790 per metric ton for flake graphite concentrate. The integration strategy has sent the sector into a frenzy of activity to prove their graphite meets expectations of battery manufacturers.  The only graphite deposit in the U.S. mainland is under development by Westwater Resources...

Smart DOE Battery Manufacturing Grants and Dilution For Dummies

John Petersen Last month I wrote about a very smart plan the DOE developed for $4.5 billion in smart grid grants authorized by the American Recovery and Reinvestment Act of 2009 ("ARRA"). I was particularly impressed that the DOE's plan created a functional public-private partnership where grants would be available to companies that could raise matching funds from private sources, but would be denied to companies that could not attract substantial private sector funding. While I hoped a similar plan would be adopted for $2 billion in ARRA battery manufacturing grants, my research was hindered by a broken link...

Alternative Energy Storage: Cheap is Outperforming Cool

John Petersen After devoting several months to articles on arcane technical and economic issues that normal investors should not have to endure, I declared a cease fire last week and advised readers that I was done with technology and planned to focus on more interesting topics like the future of the energy storage sector and making money from energy storage investments. I've spent enough time discussing trees. Now I want to evaluate the forest and show investors how to position their portfolios for the coming of cleantech, the sixth industrial revolution. I hope old friends and new...

VRB Power Systems (VRB.V) announced that Magnetek's Telecom Power Systems Group (TPS) has entered into a Letter of Intent to purchase eighty 5kW VRB Energy Storage Systems to be sold to telecom market operators in the U.S. VRB Power will supply the core-technology for the VRB-ESS units, which will generally include the overall design, cell stacks, electrolyte, tanks and the balance of the battery system, whereas TPS will be responsible for supplying the electronics, including the rectifier and controller, and assembling and integrating the components into finished VRB-ESS units. TPS will market and sell these VRB-ESS units to...

Why Advanced Lead-Acid Batteries Will Dominate the HEV Markets

My last article, "The Obama Fast Track for HEVs" graphically highlighted some critical cost issues that I've been writing about for several months and was surprisingly popular with readers. After responding to numerous comments and considering the gaps in that article, I believe a follow-on article is appropriate to provide additional color, put a finer point on the differences between advanced lead-acid and lithium-ion batteries and try to relate those differences to the rapidly evolving HEV markets. As I explained last week and in a November 2008 article titled "Alternative Energy Storage; Lithium, Lead or Both?"...

Lux Research Dissects Lithium-ion Battery Mythology

John Petersen We all know that you can't have a cost-effective electric car without a cost-effective battery. We also know that a small but vocal hodgepodge of ideologues, activists, politicians and dreamers wants everyone to believe that rapid and stunning advances in lithium-ion batteries will finally make the dream a reality after a century of one abject failure after another. I frequently caution readers that it won't be anywhere near as easy as the proponents claim. In a new report titled "Searching for Innovations to Cut Li-ion Battery Costs" Lux Research did a yeoman's...

Shares in Energy Conversion Devices Purchased

Energy Conversion Devices Inc (ENER) opened up trading this morning with a gap down to the $33 level. For the last hour it has been steadily rising up from this point. As I said in my earlier post, I have been looking for a good entry point in this company and feel that the near term support of $33 is an ideal area to place an order. The stock has been on a run for several months and it is always hard to take a new position in a stock that has already seen dramatic increases...

A Tale of Two Battery Companies

John Petersen The last few weeks have offered a fascinating object lesson for believers in Benjamin Graham's theory that "In the short run the market acts like a voting machine, but in the long run it acts like a weighing machine." Since January 4th I've watched in awe as Exide Technologies (XIDE) lost roughly 30% of its market value and Ener1 (HEV) lost closer to 40%. The difference is that Exide took a voting machine beat down because it lost a well-known but financially immaterial customer while Ener1 seems to be caught in the early stages of a...

Plug-in Vehicles Combine Immense Risk With Insignificant Reward

John Petersen Albert Einstein once said, "If you can't explain it simply, you don't understand it well enough." So when the editor of Batteries International asked if I could present my analysis of plug-in vehicles in two pages and prove my numbers in a way that any open-minded adult could follow, understand and verify with an Internet search engine, I jumped at the challenge. The article was published yesterday in their Winter Edition. Since the numbers have profound implications for the energy storage sector and an expected flurry of ill-conceived electric vehicle projects like the planned Tesla Motors...

What I Learned During Last Week’s Visit With ePower

John Petersen Last week I spent a couple days with ePower Engine Systems working my way through a variety of business and technical due diligence issues. As always happens with new clients, it was a full immersion course in how ePower’s technology works, what the documented performance of the current tractor is, and how that performance is expected to change as ePower: transitions from a four cylinder engine designed for stationary use to an EPA compliant six cylinder engine designed for the trucking industry; automates a new charge control system that will opportunistically charge the batteries in...

Will New CAFE Standards Make Stop-Start Engine Technology Standard Equipment?

John Petersen On April 1st the National Highway Traffic Safety Administration (NHTSA) and the Environmental Protection Agency (EPA) announced a joint final rule establishing fuel economy standards for all light duty vehicles sold in the United States. Since the existing standards don't apply to light trucks, I used vehicle sales forecasts from the Energy Information Administration's "Annual Energy Outlook 2010" to estimate a current baseline fuel economy of 19.6 mpg. The new rules will be phased in over a five-year period beginning with the 2012 Model Year and are certain to drive rapid evolution in the auto industry....

Ener1 And Delphi Sign LOI To Form Lithium Battery Joint Venture

ENER1 INC (ENEI) and Delphi Corp. (DPH), today entered into a non-binding letter of intent to create a joint venture to leverage their combined expertise in lithium batteries. Delphi and Ener1 will be negotiating definitive agreements and conducting due diligence in the coming weeks. "The combination of Ener1's vapor deposition process and its nanotechnology for production of high-rate, low-cost lithium batteries with Delphi-developed high energy capacity technology would allow the venture to have a key advantage in penetrating its target lithium battery markets," — Kevin Fitzgerald, Ener1's CEO. ENEI is up over 14% on this news...

US Should Approve A123’s Sale

Doug Young A123 Systems battery cell products (Source: A123) In writing this blog, I generally try to keep my own views muted and focus instead on the latest news and what it means for the companies involved. But I'm making one of my occasional exceptions to that rule today to say that the US really should go ahead and approve the sale of bankrupt battery maker A123 Systems (OTC:AONEQ) to a Chinese company, since this deal seems to have few if any national security implications and blocking...

GE Enters the Grid-based Energy Storage Business

John Petersen I've been writing about the rapidly evolving market for manufactured energy storage devices in grid-based applications since last August when I published Grid-based Energy Storage: Birth of a Giant. At the time, only a handful of smaller public companies were working on grid-based storage solutions including Maxwell Technologies (MXWL), Beacon Power (BCON), Altair Nanotechnologies (ALTI), Active Power (ACPW) and Axion Power International (AXPW.OB). Last November, France's Saft Group (SGPEF.PK) announced a partnership with Switzerland's ABB Group (ABB) to develop and commercialize utility scale solutions. Yesterday, General Electric (GE) joined the fray when it announced plans to...

The Rocky Road to Lithium Ion Battery Commercialization

by Debra Fiakas CFA A bit of history… Schematic of a Lithium Ion Battery by Materialsgrp, via Wikimedia Commons Lithium ion batteries are a relatively recent innovation.  Scientists and engineers first began working with lithium applications in the 1970s.  A number of companies and laboratories worked through the next decade to perfect lithium ion batteries, using various materials for the business ends of a battery  -  the anode and the cathode.  It was not until the mid 1980s that developers settled on cobalt as...
