There is a lot of talk on the subject of fast charging in the electric vehicle world. In principle, you cannot have both high energy density AND fast charging built into the same battery. There are many reasons for this, however, the graphite anode is the main block to fast charging. Currently “power” cells with graphite anodes can charge as fast as 75% in 15 minutes while “energy” cells require >1.5 hours. Future anodes such as silicon may bring larger capacities AS WELL AS faster rates of charging. Enevate discloses how in this patent. Listen to my podcast to learn more.

Claudiu B. Bucur obtained his Ph.D. in 2008 from Florida State University under the mentorship of distinguished Leo Mandelkern Professor of Polymer Science, Joseph B. Schlenoff. He studied the manner in which polyelectrolyte multilayers assemble, and how doping them with ions changes their mechanical and thermodynamic properties. In 2010 he completed his postdoctoral studies at the USDA Agricultural Research Service Labs, where he investigated corrosion inhibition via biomembranes. Dr. Bucur then joined the Post Lithium Ion Research Group at the Toyota Research Institute of North America, where he focused on metallic anodes such as magnesium, lithium, sodium, and their electrolytes as well as high capacity conversion cathodes such as the sulfur cathode. He expanded upon his experience with polymers, corrosion, and interfaces and was able to advance many areas in the battery field. Currently, Dr. Bucur is Chief Engineer for new battery and solid electrolyte projects at Great Wall Motor, the largest SUV manufacturer in China. He is fascinated by energy storage and dreams of creating the ultimate battery. View all posts by Claudiu “Bobby” Bucur
