Taking batteries to the skies

A decade ago, I opened my seminar at Carnegie Mellon University comparing the curb weight of Tesla Roadster and Lotus Elise. Then, I made a now-obvious take that batteries would take the place of combustion reshaping the automotive industry, and thereby mechanical engineering. Now, it’s time to make a new…

Energy-efficiency of flying cars

Flying cars have been the epitome of high technological advancements and utopia for several decades. The vision for urban air transportation is to eliminate the runway for take off and land to minimize space usage, a scarce resource in cities. Along with this vision, there is hope for sustainability, enabled…

Activating the Electrochemical Magic: A twist in the tale

Electrochemical reactions are at the core of the electrification transformation in electric cars, aircraft, and electrolysis for hydrogen production. The rate of electrochemical reactions governs a number of key metrics: fast charging in electric cars, the ability to take-off and land in electric vertical take-off and landing aircraft and unit…

Is Machine Learning ready to tackle the “AND problem” of Batteries?

October 15th marked my one-year anniversary as Chief Scientist at Aionics Inc. This gives me a chance to reflect on my assumptions from a year ago on whether machine learning is ready to tackle challenges in practical battery materials design and optimization. Those that know me know that I take…

Reaction rate laws key to unlocking lithium metal batteries for flying cars and fast charging

2020 has been the year for lithium metal. Lithium metal batteries, which promise to deliver about 50% improvement in energy delivered per weight and volume, appear to be ready for primetime. The main challenge thus far has been to stop the formation of dendrites, needle-like patterns of metal deposition that…

Cinema displays meet Batteries

Lithium metal batteries have drawn enormous attention over the last month. Lithium metal is the holy grail in batteries as it has the potential to bring a substantial boost to the energy density over current Li-ion batteries. One of the central problems in using metallic lithium involves suppressing the formation…

A cross-country trip from the future

I was going to spend a portion of my summer in California and I was debating whether to drive cross-country or have a rental for my summer stay. Cross-country trips are challenging enough but in this case, it turns out to be even more interesting since I drive a Tesla…
