Will this Turn Out to Be the Battery Breakthrough We've Been Waiting For?
It's still too early to tell if this lithium-air battery technology
will perform well enough to make its way to real-world products, but
the lab results that have been publicized so far are very promising.
With current battery chemistry, "energy storage is limited by the
lithium cobalt oxide electrode (0.5 Li/Co, 130 mAhg-1).
The University
of St Andrews design replaces the lithium cobalt oxide electrode with a
porous carbon electrode and allows Li+ and e- in the cell to react with
oxygen from the air." This could allow up an increase in storage
capacity by up to 10x. Read on for more details.

Nanosolar
said Wednesday it has created the industry’s largest solar production
tool: a thin-film coater that has the capacity to produce up to 1
gigawatt of solar cells annually.
That compares with 10 to 30 megawatts of annual
production capacity for most solar production tools, CEO Martin
Roscheisen wrote on the company’s blog.
The tool, which uses the Nanosolar’s nanoparticle ink,
costs $1.65 million and – at the speed at which it’s currently running,
100 feet per minute -- produces cells for a hundred times less than a
high-vacuum process, he wrote.
Roscheisen, who also included a video
of the tool in his post, said the company expects the tool to have the
potential to reach speeds of up to 2,000 feet per minute.
He added that the tool delivers cells that can convert sunlight into electricity with up to 14.5 percent efficiency, but declined to answer a question about the average efficiency of the cells that are being produced.
