Is this brand new type of battery the key to clean energy and off-grid electricity?

Lithium-ion batteries are having a moment. After becoming the de facto battery in laptops and cell phones over the years, they’re now starting to power electric cars (like those made by Tesla) and plug into the power grid.

But lithium-ion batteries aren’t the only battery type in town. Some brand new battery varieties could actually be more promising than lithium-ion when it comes to storing energy generated by solar panels or used to power remote villages in Africa, India, and Asia.

Friends have been asking me to write something on space exploration and my campaign policy on it, so here it is just out on TechCrunch:


When people think about rocket ships and space exploration, they often imagine traveling across the Milky Way, landing on mysterious planets and even meeting alien life forms.

In reality, humans’ drive to get off Planet Earth has led to tremendous technological advances in our mundane daily lives — ones we use right here at home on terra firma.

I recently walked through Boston’s Logan International Airport; a NASA display reminded me that GPS navigation, anti-icing systems, memory foam and LED lights were all originally created for space travel. Other inventions NASA science has created include the pacemaker, scratch-resistant lenses and the solar panel.

The future of movies and manufacturing may be in 3D, but electronics and photonics are going 2-D; specifically, two-dimensional semiconducting materials.

One of the latest advancements in these fields centers on (MoS2), a two-dimensional semiconductor that, while commonly used in lubricants and steel alloys, is still being explored in optoelectronics.

Recently, engineers placed a single layer of MoS2 molecules on top of a photonic structure called an optical nanocavity made of aluminum oxide and aluminum. (A nanocavity is an arrangement of mirrors that allows beams of light to circulate in closed paths. These cavities help us build things like lasers and optical fibers used for communications.)

Creating Q-Dots/ QDs (Acronym seems to depend on which reference book, article that you read) more cheaply and efficiently too.


Quantum dots (QDs) are semiconducting nanocrystals prized for their optical and electronic properties. The brilliant, pure colors produced by QDs when stimulated with ultraviolet light are ideal for use in flat screen displays, medical imaging devices, solar panels and LEDs. One obstacle to mass production and widespread use of these wonder particles is the difficulty and expense associated with current chemical manufacturing methods that often requiring heat, high pressure and toxic solvents.

But now three Lehigh University engineers have successfully demonstrated the first precisely controlled, biological way to manufacture quantum dots using a single-enzyme, paving the way for a significantly quicker, cheaper and greener production method. Their work was recently featured in an article in The New York Times called “A curious tale of quantum dots.”

The Lehigh team— Bryan Berger, Class of 1961 Associate Professor, Chemical and Biomolecular Engineering; Chris Kiely, Harold B. Chambers Senior Professor, Materials Science and Engineering and Steven McIntosh, Class of 1961 Associate Professor, Chemical and Biomolecular Engineering, along with Ph.D. candidate Li Lu and undergraduate Robert Dunleavy—have detailed their findings in an article called “Single Enzyme Biomineralization of Cadmium Sulfide Nanocrystals with Controlled Optical Properties” published in the Proceedings of the National Academy of Sciences (PNAS).

‘Zero-energy’ buildings — which generate as much power as they consume — are now much closer after a team at Australia’s University of New South Wales achieved the world’s highest efficiency using flexible solar cells that are non-toxic and cheap to make.

Until now, the promise of ‘zero-energy’ buildings been held back by two hurdles: the cost of the thin-film solar cells (used in façades, roofs and windows), and the fact they’re made from scarce, and highly toxic, materials.

That’s about to change: the UNSW team, led by Dr Xiaojing Hao of the Australian Centre for Advanced Photovoltaics at the UNSW School of Photovoltaic and Renewable Energy Engineering, have achieved the world’s highest efficiency rating for a full-sized thin-film solar cell using a competing thin-film technology, known as CZTS.
