Game Changer
Most important part: The battery retains 90% of Capacity after 5,000 charges. Toshiba’s advancement focuses on the lithium-ion cells’ anodes. In place of the lithium-titanium oxide anodes the company uses on its current-generation lithium-ion batteries, there are titanium-niobium oxide (TNO) pieces. Combined with a method for storing lithium ions “more efficiently in the [cell’s] crystal structure,” TNO anodes are claimed to double the energy capacity of Toshiba’s current offerings. Initial testing has revealed the new cells maintain “over 90 percent” of their capacity after 5000 cycles with the ability to be rapidly charged, even in cooler temperatures as cool as 14 degrees Fahrenheit (where the charge time increases slightly, to 10 minutes). Perhaps most important is that Toshiba promises that these lithium-ion cells with the TNO anode will be available in 2019. |

This is great news for the 8 year olds that dig up Elan Musk's Lithium for the electric cars.

Sounds more like a Super Capacitor battery hybrid than a pure battery.
I wonder how long it would stay charged when not driven? a day? a week? If it holds the charge over a month reliably, then it's definately going to change things from phones to cars, but if it self-discharges whether you're driving or not, it will have limited utility. That's the biggest issue with super capacitors getting larger right now. |

This is a pretty big deal. Capacity, lifespan and charging time have always been the Achilles heel of Electric cars. All of them have improved significantly over the last decade, but not to a point where most people can honestly swap out a gas vehicle, largely due to range/charge time considerations. (Cost is another issue, but we'll leave that alone)
You make a battery system that can get you 300 miles and be charged back to full while you're eating lunch? Game changer is right. |

Gonna put this right near the rest of the stack of "battery breakthrough game changer never been dun befo" items and wait until it's actually on the fucking market before getting excited.
There are dozens of announcements like this every year, none of them fruition into anything at all. |

On the contrary. That new lithium battery would be a big help for them. Their cars currently run off of several thousand 18650 lithium batteries. These new batteries will shorten the Tesla car's charging time and increase their range. I've wondered why Tesla doesn't incorporate solar cells into the roof, hood, and trunk lid of their cars so they would be constantly charging the batteries as long as they were exposed to the sun. Would just require redesign of regular solar cells into an integrated array that could be designed to appear to be part of the hood, roof, and trunk lid. Tesla probably won't do it because it would increase the cost by $15,000 for a charge rate of 1 mile per day. |

Just think in a few years the robots will be doing it. Then how is junior gonna eat? Maybe they can give him some UBI |

Why don't they use capacitors? What's the max capacity of capacitors which could be carried by an EV? The biggest issue they're going to run into is that our power grid/outlets aren't built for continual 10kW surges when several people in a row decide to charge their car fast. (Estimated power draw after losses) Especially during daytime, when brownouts already happen if more than ¾ of customers have AC running. |

VERY interestingly, the specific energy density of Lithium-Air batteries is greater than that of most chemical explosives.
If this Wiki article is true, that is. https://en.wikipedia.org/wiki/Energy_density_Extended_Reference_Table It doesn't even address newer battery technologies than Li-air. |

What REALLY REALL REALLY gets neglected in this "200 miles of range in 5 minutes of charging!" is...
that is a FUCKTON of power being transferred in such a short period of time. You need a HUGE YUGE YUUUUUUUGGGEEEEE source of power to push that much energy into a battery. Yeah, I think electric cars are good, and I think they'll get much cheaper and much more practical, in part by things like this battery, and yes, I do think that infrastructure will be developed to do this superfast charging... but I always think it's weird as fuck no one bothers to do the math about how much power it actually takes to charge a battery like that in such a short time. |

Prius had an option like that. Tesla probably won't do it because it would increase the cost by $15,000 for a charge rate of 1 mile per day. Quoted:

Uhh... hate to crap on the party guys, but we have a problem....
