Shin-Etsu Chemical company working on a new type of battery for smartphones that could last a week. That would be revolutionary, I would literally be able to sleep better at night not having to worry if my phone is charging, or having to carry an extra charger with me every where I go. This new silicon based battery could go a long way, not just smartphones, all electronics from laptops to cars. Apple’s MacBook 10 hour battery life might not be a big deal anymore, and electric cars are just getting started.
