CalBattery Selected For TechConnect National Innovation Award

LOS ANGELES, CA – California Lithium Battery is proud to announce its selection as a 2013 TechConnect National Innovation Awardee for the development of its breakthrough very-high specific capacity Lithium-ion silicon-graphene (SiGr) composite anode material. CalBattery will present full-cell Li-ion battery test results at the TechConnect National Innovation Showcase on May 14th in Washington, D.C.

Each year the TechConnect Innovation Awards committee selects the top early-stage innovations from around the world submitted to the TechConnect Innovation Summit. Rankings are based on the potential positive impact the technology will have on a specific industry sector.

“With hundreds of innovative technologies to choose from, we are delighted that TechConnect identified our silicon-graphene anode battery material as having the potential to be a game-changer in the Li-ion battery industry,” said Phillip Roberts, President of California Lithium Battery. “It is clear that today’s battery technologies are not capable of meeting the performance and cost challenges demanded by the marketplace. Whether used in smart phones, EVs, or energy storage systems, our SiGr anode material has shown to dramatically improve the performance of Li-ion batteries in combination with existing or new high-energy density cathode or high-voltage electrolyte materials”, stated Roberts.

Recently, the CalBattery SiGr anode material was chosen for testing by Quallion as part of a government funded two year li-ion battery development project for satellite use applications.

The Innovation Showcase is the world’s largest showcase and accelerator for industry-vetted emerging-technologies that are ready for commercialization.

Peak Battery: Why Smartphone Battery Life Still Stinks, and Will for Years

Pushing Lithium-Ion’s Limits

Virtually every smartphone today relies on lithium-ion batteries, which provide power by transferring electrons between the anode and cathode of a battery cell. The amount of lithium ions inside the battery directly affects how long your phone can last on a charge.

The problem lies in the graphite that stores lithium ions in the anode of a battery. Graphite has a theoretical limit to how much lithium it can hold, and today’s batteries have pretty much reached it. While bigger batteries are always an option–as seen in Motorola’s Droid Razr Maxx–most people don’t want thicker, heavier phones, so phone makers sacrifice battery life in the name of slenderness.

With graphite-based anodes reaching peak capacity, the race is on to replace graphite with silicon, a material that can offer ten times the capacity of today’s batteries–at least in theory.

“There’s a lot of research going on, because silicon is the best material for absorbing lithium, and it has the highest potential capacity of any material now,” said Phillip Roberts, CEO of California Lithium Battery.

Swapping silicon for graphite isn’t easy. Silicon swells while charging, causing electrical contacts to break during discharge, and ultimately degrading the battery. That’s a dealbreaker for smartphones, which need to survive through at least a couple of years’ worth of daily recharging.

California Lithium Battery is working on a composite of silicon and graphene–a Nobel prize-winning material made from atom-thick layers of graphite–that combines the capacity of the former with the stability of the latter. And unlike some other silicon-based anode solutions, this composite, which is licensed from Argonne National Laboratory, prevents the agglomeration of silicon that leads to swelling and reduced cycle life, Roberts said.

Roberts hopes that within six months, the company can produce material by the metric ton and send it out to battery makers and phone makers for testing. In two years, the company expects its silicon-based anode to replace the graphite-based anodes in existing batteries, bringing a 30 percent improvement in capacity.

“I would say within two years, you’re going to see that technology. It’s happening relatively quickly. Behind the scenes, there’s a lot going on,” Roberts said.

When paired with other advances in cathode and electrolyte materials, he expects capacity to improve by 100 percent, possibly within three years.

Companies working on silicon anode technology have also felt the pressure from battery and device makers. California Lithium Battery was attracting so much attention that it changed its initial focus from electric cars to consumer electronics. CEO Phillip Roberts said “pretty much every smartphone maker” has shown interest in the company’s technology. “We haven’t contacted one company ourselves,” CEO Phillip Roberts said. “Every group so far that we’re working with contacted us.”

You have to wonder, though, how phone makers will use new battery technology once it’s available. Will they finally deliver the rock-solid, 24-hour batteries that we need, or will they push for ever-thinner devices that are just nice to look at? It seems we have a least a couple years to agonize over the answer.

Argonne and CalBattery Strike Deal for Silicon-graphene Anode Material

LEMONT, Ill. – The U.S. Department of Energy’s Argonne National Laboratory, located outside of Chicago, and California Lithium Battery, Inc. (CalBattery), a Los Angeles Cleantech Incubator portfolio company, announced today that they have signed a licensing agreement for an Argonne-developed, silicon-graphene composite anode material for high-energy lithium batteries.

CalBattery plans to move forward rapidly in the commercial scale-up and production of this breakthrough novel composite anode material, which tests show triples the energy capacity of the state-of-the-art graphite anode.

CalBattery has worked with Argonne for more than a year under a Work for Others agreement to develop the technology under the DOE’s Startup America program, which is part of a White House initiative to inspire and accelerate high-growth entrepreneurship. Startup America pairs innovative individuals, businesses, universities and foundations with a broad range of federal agencies with the goal of significantly increasing the number and success of American entrepreneurs.

“The CalBattery-Argonne collaboration is a shining example of the national public-private partnership enabled by DOE’s America’s Next Top Energy Innovator part of Startup America,” said Dr. Karina Edmonds, Technology Transfer Coordinator for DOE. “This technology was originally developed at the Department of Energy’s Argonne National Laboratory as a result of Argonne’s ongoing pursuit to produce advanced battery materials that will substantially improve battery performance with products that startup companies can then take to global markets. This is the type of partnership envisioned by Startup America to boost U.S. competitiveness by supporting the high-growth startups across the country.”

“An important part of a national laboratory’s role is to perform research that enables U.S. industry to develop and manufacture advanced technologies to be marketed both domestically and internationally,” said Jeff Chamberlain, who heads Argonne’s Energy Storage Initiative and is Deputy Director of the Joint Center for Energy Storage Research Energy Innovation Hub.

“Argonne’s research efforts support the continued development of the American economy, as well as job creation; so we are extremely pleased that the lab has been able to help CalBattery attain its goals by working with the company to develop an anode technology that it will be able to manufacture and commercialize,” Chamberlain added. “This deal demonstrates the Department of Energy’s enthusiastic and practical support of research that supports entrepreneurship and U.S.-based start-ups. It also reflects the value DOE places on basic science as the basis for innovative advanced technologies like advanced lithium-ion batteries.”

CalBattery is a portfolio start-up company headquartered at the Los Angeles Cleantech Incubator (LACI), which was started by The City of LA and the LA Department of Water and Power in 2011.
