New Battery Technology, COVID Rise From Unvaccinated Populations. July 16, 2021, Part 1
Research For New Battery Technology Is Gaining Steam
As countries around the world set their goals for decarbonizing their economies, it’s becoming clear that batteries may play a pivotal role in smoothing out the peaks and valleys of solar and wind power productions, as well as driving a shift to electric vehicles, and providing power for other parts of our lives.
Lithium-ion batteries are now the standard. They run electric cars and power your laptop and cell phone. But they have major drawbacks, like overheating and their high costs. The supply chain and environmental impact of lithium-ion power cells also raise concerns: mining the materials—like lithium, cobalt, and other metals—requires polluting, water-intensive processes. While many deposits are only found in foreign locations, some U.S. companies are now looking to mine domestically, concerning environmental advocates.
The search for a better battery is on, and promising developments include new chemistries for efficiently storing energy, and smarter ways to plug them into the grid. This week, Ira talks to IEEE Spectrum senior editor Jean Kumagai, and Argonne National Laboratory’s Venkat Srinivasan about the promises, the roadblocks, and what to watch for in future battery technology.
A Tale Of Two Pandemics
During the COVID-19 pandemic, we’ve seen many different aspects of the illness—the early surges and community shutdowns, the debates over schools and masks, and, now, signs of hope as more people are vaccinated and communities reopen.
But the story is different among unvaccinated populations. In many snapshots of new infections, hospitalizations, and deaths, those affected are overwhelmingly unvaccinated people. Even as the value of vaccination becomes more apparent, some people are still resistant to the vaccines.
And in Tennessee, government officials told public health workers to stop vaccination outreach to young people—not just for COVID-19, but for all childhood vaccinations.
Amy Nordrum of MIT Technology Review talks with Ira about the latest in the pandemic, and the importance of vaccination in the face of the rising COVID variant known as Delta.
