Enzymatic fuel cells containing a 15% (wt/v) maltodextrin solution have an energy-storage density of 596?Ah?kg 1 , which is one order of magnitude higher than that of lithium-ion batteries. Sugar is a perfect energy storage compound in nature. The enzymes and fuels used to build the device are biodegradable.

Q&A with Smartville CEO and co-founder Antoni Tong What do EV batteries have in common with athletes and politicians? Once they age out (or get voted out) of their positions, they have the opportunity to have a lucrative (and in the case of batteries, useful) second career.

A team at Stanford University has developed stable silicon Li-ion battery anodes by incorporating a conducting polymer hydrogel into the Si-based material. Stanford scientists used a battery fabrication process to make novel silicon/hydrogel electrodes. Each SiNP is encapsulated in a conductive polymer surface. Click to enlarge.

The cross-section of an organic crystalline all-solid battery. A pair of researchers at Tohoku University in Japan have developed a novel rechargeable solid-state lithium battery with an organic crystalline cathode. The battery features a novel cell design which prevents dissolution of the organic cathode compounds.

Fleet vehicle depots will need to incorporate not only charging stations, but energy management systems, and possibly energy storage and on-site generation. We are able to own those types of assets, and we are structured in a way that can bring a low cost of capital to finance those assets.

Measurements also indicate that these new materials could yield a cathode that is extremely energy-efficient. A patent related to this work was filed in January of this year, titled “High-Energy Cathodes for Lithium Rechargeable Batteries.” These fixes may be explored in future studies. —Feng Wang.

The PHEV does not require the heavy, costly batteries required by other electric cars, nor does it suffer from a limited range or poor freeway performance. Though the PHEV combines the two types of energy and power, it is not merely a temporary “transition” between gasoline and diesel cars to pure electric cars.

The United States has started to realize that China could dominate the future of transportation—electric transportation—if it does not counter the current Chinese influence over critical parts of the EV supply chain, from battery metals sourcing and processing to battery manufacturing.
