    Lithium-ion batteries are everywhere, in smart phones, laptops, an array of other consumer electronics, and the newest electric cars. Good as they are, they could be much better, especially when it comes to lowering the cost and extending the range of electric cars. To do that, batteries need to store a lot more energy.

    The anode is a critical component for storing energy in lithium-ion batteries. A team of scientists at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) has designed a new kind of anode that can absorb eight times the lithium of current designs, and has maintained its greatly increased energy capacity after over a year of testing and many hundreds of charge-discharge cycles. [...]

    Long lasting very high density batteries would be a game changer. Electric cars could have more range than today's gasoline cars. Electric cars would have far fewer moving parts and much longer time between failures too.

    Those compact fluorescent lightbulbs contain mercury. So much for saving the environment when you throw them in the landfill.

    We recycle.

    I have read an article like this every six months for 30 years. The last big one was about Super Capacitors. Basically they are BS PR to raise money or to meet research paper quotas. Tho techically true they are never practically possible. For instance the batteries are 10x more powerful but they only work operated at 300 degrees f.

    Except that the technology in batteries has improved substantially even in the last 10 years...
