Nobel price goes to Lithium-ion battery inventors but …

The MIT Technology review provides a comprehensive overview on what this nobel price means. After 100 years, lithium-ion batteries are a significant step towards more usable batteries. It brought us a step closer to a more practical use of “portable” and “mobile” use of stored electric energy. But as the article says, we still have to overcome many practical hurdles to allow scaling up the use of batteries that we can we really speak of an energy transition.  We believe that carbon based hybrid power capacitors are a significant step in the right direction. By combining the energy density of lithium-ion battery cells with the power density of carbon based supercapacitors,  we have a much more practical solution. A solution that also meets other requirements like safety, robustness, long life time,  fast charging, simple to put at work, cost-efficient and less stressing on the environment.

Lithium-ion’s pioneers nabbed the Nobel. Now we need the next battery breakthrough.

Tesla is using lithium-ion batteries to build some of the world's biggest grid battery plants.

As chemistry advances go, few rival the impact of the lithium-ion battery.

The light, compact batteries power much of the modern world, including our smartphones, laptops, and electric vehicles and, increasingly, the electricity system. On Wednesday, three scientists who played major roles in the technology’s development won the Nobel Prize in chemistry, splitting the more than $900,000 award.

Background: To make really energy-dense batteries that work well in portable products, you need a light and highly reactive material. Lithium nicely fits the bill: it’s the lightest solid element and readily relinquishes its electrons, the negative charged particles that create an electric current as they flow between a battery’s electrodes, explained the Royal Swedish Academy of Sciences.

The details: The Nobel committee awarded the prize to Stanley Whittingham of Binghamton University, who “developed the first functional lithium battery” in the early 1970s; John Goodenough of the University of Texas at Austin, who “doubled the battery’s potential” in 1980; and Akira Yoshino of Meijo University, who helped make the fire-prone batteries safer in 1985 by switching from pure lithium to lithium ions, which carry a net charge thanks to missing or extra electrons.

Improved safety was the key to making the batteries a commercial product. Sony and Asahi Kasei first produced the batteries in 1991. They quickly found their way into camcorders, computers, MP3 players, mobile phones, and more. The price and performance of the batteries have continued to improve as demand and manufacturing rapidly expanded, consistently exceeding expectations of academia and industry.

But … There are still limits to what lithium-ion batteries can do, and ongoing issues with safety. Their costs still need to fall further to narrow the price difference between EVs and gas-powered vehicles, and they’re still not light or powerful enough to electrify most of the trucking, shipping, and aviation industries. Finally, most battery experts say we’re going to need entirely different chemistries for energy storage that will be cheap and long-lasting enough to balance out the fluctuations in solar and wind power as they come to dominate the electricity grid.
