5 future battery technologies to make your phone last longer and charge faster
Battery tech energy density and maturity chart
It won't be long before everything - from our cell phones, through our cars, to our houses - uses some sort of electricity storage that ought to be cheaper and much more efficient than what we have now. The current Li-ion technology has been good to us, but is nearing its limits, with potential about 30% above current levels at the maximum, and that's that, say researchers.
That's why we are rounding up a few of these promising inventions that should finally put to rest our range and battery endurance anxieties, and what you will see in the slideshow below are good candidates for those multimillion bonuses when the breakthroughs reach commercial viability.
