Speakers at MIT Enterprise Forum Promote the Benefits of Clean Energy Storage

LifeCel Technology of Goleta is helping lead the charge with its development of a lithium-ion battery

The missing link in renewable energy, according to UCSB professor Daniel Morse, is properly storing clean energy so it can be transported efficiently and called upon when needed.

Morse, a professor of biochemistry and engineering at UCSB and founder of LifeCel Technology, and David Auston, executive director of the UCSB Institute for Energy Efficiency and Center for Energy Efficient Materials, discussed clean energy storage Wednesday night at the MIT Enterprise Forum Central Coast.

Auston said gasoline-powered motors are about 25 percent efficient while most energy is emitted as waste heat. Power plants operate at about 30 percent efficiency, and buildings at about 50 percent.

“It is estimated that at least 30 percent of total energy consumed in the U.S. is not only wasted, but could be captured and saved through more efficient technology deployment,” he said.

Electric vehicles and renewable energy sources won’t be widely deployed unless storage costs decrease and the process becomes more efficient, according to Auston. He said that’s where companies such as LifeCel Technology and Transphorm come into play.

Morse and a UCSB team founded the Goleta-based startup LifeCel, which developed a cheap, high-power and safe lithium-ion battery.

Morse said LifeCel batteries have 50 percent more energy capacity, use 70 percent less platinum and are 11 times more powerful than commercial batteries.

“It’s a biologically inspired approach to making nanostructured components for more efficient batteries,” he said. “We also create next-generation fuel cells, a kind of hybrid between a generation of power source and means of transforming the energy content of that gasoline, hydrogen or alcohol to electricity.”

Typical commercial batteries added silicon to the graphite to increase the energy and power. But Morse said the problem is that silicon swells when ions go through it, it shrinks when the ions are discharged, and the silicon breaks apart and loses the connectivity to the leads that power the device.

LifeCel creates nanocrystals of tin inside graphite or carbon nanotube structures to increase power and improves safety through its fire-proof barium strontium titanate nanocrystalline ceramic. Morse said the technology can extend the battery life in notebooks, smartphones and other portable electronics and battery can be charged or discharged in less than two minutes.

“The higher cyclability and stability of the batteries increases safety, and LifeCel offers readily scalable manufacturing,” Morse said. “It’s a generic platform technology, and we can work with a wide variety of metal oxides and a wide variety of matrix supports to make the nanocomposites, so there are a wide range of applications.”

Noozhawk Asks: What’s Your Question?

Welcome to Noozhawk Asks, a new feature in which you ask the questions, you help decide what Noozhawk investigates, and you work with us to find the answers.

Here’s how it works: You share your questions with us in the nearby box. In some cases, we may work with you to find the answers. In others, we may ask you to vote on your top choices to help us narrow the scope. And we’ll be regularly asking you for your feedback on a specific issue or topic.

We also expect to work together with the reader who asked the winning questions to find the answer together. Noozhawk’s objective is to come at questions from a place of curiosity and openness, and we believe a transparent collaboration is the key to achieve it.

The results of our investigation will be published here in this Noozhawk Asks section. Once or twice a month, we plan to do a review of what was asked and answered.

Thanks for asking!
