Researchers Win Nobel Prize for Battery Tech
This year's Nobel Prize in chemistry has gone to researchers for their advances in lithium-ion batteries for everything from smartphones to electric vehicles.
The Royal Swedish Academy of Sciences has awarded this year’s Nobel Prize in Chemistry to three researchers who worked independently to improve lithium-ion batteries for everything from smartphones to electric vehicles.
The winners are John Goodenough (University of Texas), Stanley Whittingham (Binghamton University in New York) and Akira Yoshino (Meijo University in Japan and Asahi Kasei Corp.) They will split the 9 million kroner ($1.3 million) award.
Whittingham laid the foundation for modern lithium-ion batteries in the early 1970s with the creation of a titanium disulfide cathode and a metallic lithium anode.
In 1980, Goodenough demonstrated a more powerful system that used a cathode made from cobalt oxide with intercalated lithium ions. Teaming Goodenough’s cathode with a petroleum coke-based anode, Yoshino created the first commercially viable lithium-ion battery in 1985.
The result was a lightweight battery that could be charged hundreds of times without performance deterioration. Power is derived from the lithium ions flowing back and forth between the anode and cathode rather than chemical reactions that break down the electrodes.
In recent years, Goodenough has worked with other University of Texas researchers on next-generation solid-state batteries. Several battery companies and carmakers also are pursuing the technology, which promises to be safer and generate three times the energy density of current lithium devices.
Lithium-ion batteries have become the technology of choice for EVs, and falling costs and rising energy levels could keep them on top for nearly two decades.
Mercedes has been putting diesels in vehicles since 1926. It has been offering them in the U.S. since 1949. And 2013 is seeing a range of offerings, including in its popular GLK SUV.
The Mazda CX-5 first appeared on the scene in 2012, and for 2017, the vehicle has undergone some major transformations, to enhance what was already a notable small crossover.
