Batteries are key to just about every one of the most beloved gadgets we all carry. We have batteries inside our phones, iPads, MP3 players, laptops, and a myriad of other gadgets. Rechargeable batteries are also prolific in electric and hybrid cars so any new process that promises twice the life for a rechargeable battery is a major victory. We typically think about run time when it comes to rechargeable batteries, but how long the batteries last is important as well.
Hitachi claims to have invented a new process that will double the lifespan of lithium-ion batteries. This is a very important breakthrough for the hybrid and electric vehicle market where batteries need to be replaced in the area of every five years at a cost of thousands of dollars.
Hitachi's new breakthrough would let the batteries used last for up to ten years before they need to be replaced. Hitachi plans to focus the battery tech to start within the grid-scale storage market for storing solar and wind power. I am sure the technology will reach other markets eventually.
