Lithium - ion battery are already close to the 20 - hour lifepromisedback in 2007 for laptops , but Lithium - sulphur batteries being worked on at Stanford University may improve stamp battery life by 300 per cent .

It ’s the same team of researchers that impressed us back in ’ 07 with tales of long - lasting Lithium - ion , but it seems the future is in atomic number 3 - sulphur batteries — specifically with the “ recent development of sulfur / mesoporous carbon nanocomposite cathodes , ” as name inNano Letters :
“ The recent development of sulfur / mesoporous carbon copy nanocomposite cathodes represents a particularly exciting cash advance , but in full battery cells , sulfur - based cathode have to be paired with metal Li anodes as the lithium source , which can result in serious safety issues ”
“ Here we report a novel lithium metal - free battery consisting of a Li2S / mesoporous carbon composite cathode and a Si nanowire anode ”
“ This newfangled battery yields a theoretical specific DOE … which is four times that of the theoretical specific energy of exist lithium - ion batteries based on LiCoO2 cathode and black lead anode . ”
regrettably for those of us wish upon a star each night for longer bombardment life in our gadgets , Stanford University ’s research is improbable to be seen in products any time soon , due to its low tutelage cycles of between 40 – 50 , significantly lower than Li - ion ’s 300 – 500 .
