New battery tech headlines always sound great - but seems as if this one is still a long ways off...
"Now for the bad news: this technology is still a decade or so away. The demonstration battery produced by the scientists still needs pure oxygen in order to charge – not something many of us have a ready supply of – and there's still the risk of the battery exploding due to the dendrites (spindly lithium metal fibres) created during the charging process. Eventually, these issues will be dealt with, but it's going to take a lot of research and experimentation first."
