Ultrathin aluminum oxide layer boosts performance of garnet ceramic solid-state batteries

By April Gocha / January 17, 2017

Researchers at the University of Maryland have designed a way to insert an ultrathin layer of aluminum oxide in between a garnet ceramic electrolyte and electrodes of solid-state batteries, decreasing impedance by 300-fold and allowing the energy to flow.

Ceramics are superior: Ceramic materials offer safer solutions to lithium-ion battery woes

By April Gocha / November 8, 2016

With the swirling debacle surrounding Samsung’s exploding lithium-ions and NASA’s accidently self-destructing robot, consumer interest in battery safety has seldom been higher—which is why ceramic materials are getting their spot in the battery technology limelight.

Video: Wachsman on ‘Role of solid oxide fuel cells in a balanced energy strategy’

By / March 15, 2013

[flash mode=1 f={image=}] Eric Wachsman been working with solid oxide fuel cells for nearly three decades and not just on the science and technology side. Wachsman also closely follows and writes on governmental policies insofar as these policies affect the development and deployment of SOFCs. In this video—an invited talk at the recent ICACC’13…

Can the US afford to pull the plug on SOFC and SECA funding?

By / November 8, 2011

Credit: Wachsman et al.; Energy & Environmental Science. No. Will it anyway? Unfortunately, it looks that way, based on the DOE’s 2012 budget request (pdf), which hacks off 41 percent of total SOFC funding from the current year budget, and would leave support at 65 percent of what it had in 2010. Moreover, it would cut off funding…

Microtubular SOFC: Small is beautiful – and cooler and powerful

By / August 20, 2009

A group from the National Institute of Advanced Industrial Science and Technology and the Fine Ceramics Research Association in Nagoya, Japan, reported in a recent issue of Science about their results in studying the anodedesign and electrochemical performance for SOFCs, including a tiny tubular SOFC that might be useful in small electronics. They prepared three…
