I can live with the short life if they are cheap. What I mean is if these batteries cost like $10 Dollars US for a pack 6 or even 4. But of course these are going to be for those custom cells that come in odd shapes for small devices. Still if the replacement is only like $10 bucks then I can handle buying a new battery every month or so for the privilege of having a battery that lets me run a laptop at full swing all day. 

Besides what ever happened to the fuel cell batteries that were supposed to give us incredible operating capacities?

People don't want to carry fuel around with them. :P

Right now, with an increase of 80% over Li-ion batteries, the charge limit could be almost ignored in certain applications.  I'm thinking long-range military and scientific instruments, remotely located temporary installations, etc.  The charge limit would be a major crutch to consumer electronics, but in certain applications the charging capacity would more than easily make up for the charge limit.

How many times have I gone across the Intrerwebs to read about the next best battery tech. that is coming out? There are at least two articles a month about new battery improvements/inventions that I read, but somehow never seem to fully materialize into the main-stream market. Point and being, how many more times must we be subjected to hearing about vast improvements to battery life before we actually DO see these "amazing" improvments?

True, but I think that unlike most of those other articles such as "tiny ultracapacitor hairs could mean instant charges!" or "nanotubes could increase capacity 300%!" articles, this seems like it is actually closer to maturing.

If they can work out the robustness to it will survive more charge cycles it sounds like a viable product, not just some recently discovered phenomenon of the molecular world that could theoretically offer advantages at some undefined time in the future.

I dunno if i like the idea of SULFER batteries, ignoreing the entire devil thing for a moment isn't sulfer like

 

HIGHLY COMBUSTIBLE?

the main anion is lithium, with the cation being sulfur, and together they form a non-metallic ion, that isn't as reactive chemically as lithium and is less flammable than sulfur.

 i figured as much but they still have to be combined, one dropped match in the factoy and well...
