Venkat Viswanathan is an associate professor in the Department of Mechanical Engineering at Carnegie Mellon University. Viswanathan’s research focus is on identifying the scientific principles governing material design, inorganic, organic, and biomaterials, for novel energy conversion and storage routes. The material design is carried out through a suite of computational methods being developed in his group, and validated by experiments. Some key research thrusts include identifying principles of electrolytes design (organic material) that can tune electrode catalysis, identification of new anode, cathode (inorganic materials), and electrolyte materials for next generation batteries, and new electrocatalysts (inorganic) and biomaterials for energy storage and separation applications. In addition to material design, his group is involved in several cross-cutting areas such as battery controls, electric vehicle security, and GPU accelerated computing.
Viswanathan received the Office of Naval Research Young Investigator Award in 2019, Sloan Research Fellowship in Chemistry in 2018, the National Science Foundation CAREER award in 2016, the American Chemical Society PRF Young Investigator Award in 2014, and the Electrochemical Society Daniel Cubicciotti Award in 2010. He was a finalist for MIT TR Innovators Under 35 in 2014, and was an Electrochemical Society Herbert H. Uhligh Summer Fellow in 2009.

Solid-ion conductors for safer batteries
Venkat Viswanathan and collaborators at Lawrence Berkeley National Laboratory investigate how a solid-ion conductor – a component that can be used as a separator between the anode and the electrolyte in a battery – can prevent dendrites.
Producing hydrogen peroxide when, and where, it’s needed
Does a material exist that can be used to selectively, reliably, and efficiently form hydrogen peroxide whenever and wherever it’s needed?

Viswanathan receives Navy award for battery research
Venkat Viswanathan received a 2019 Young Investigator Award from the Office of Naval Research to research how to improve battery safety in low temperatures.
Viswanathan discusses future of electric planes
A battery-powered plane would be quieter, cheaper, and cleaner than the current options. But for it to be feasible, batteries would need to be safer, pack in more energy, and discharge energy more quickly. MechE’s Venkat Viswanathan says that the kind of technological leap needed for an all-electric commercial plane will likely take decades.
Viswanathan on Audi e-tron battery
In a Quartz article, MechE’s Venkat Viswanathan discussed the discrepancy between the large battery size but low range of Audi’s first all-electric car, the new e-tron. According to Viswanathan’s calculations, “Something doesn’t add up.” He notes that because the e-tron is Audi’s first electric car, the company may be playing it safe while playing catch up to Tesla, who have had a head start in improving battery efficiency.
