I've been hearing about batteries that charge quickly and last a long time for 10 years now. Not much has changed in what is available... ...and since that article mentions Tesla's, you could not pay me enough to sit on top of a battery big enough to power a car. It's not how I want to die.
My Huawei HAM 2 phablet charges up in a flash as I see it. Only an hour and even less if I catch it before it goes too low. Personally don't need a 5 minute charger. I go nearly 3 to 4 days without a juice up and a whole working week if it just sits around. The Honor 5X finally updated and fixed a really bad battery drain (was using 4 cores all the time instead of 1) FIXED! That one charges up longer but then it doesn't have the 4050 mAh power pack like the Mate does either.
All smartphones charge in 5 min - just not to the full capacity On a slightly more serious note, the problem with supercharging is the heat. You can blast a battery with a million amperes current, the question is, will it still remain intact once you're done. The higher the voltage, the current, etc, the more heat needs to be dissipated, which makes it tricky for a small, crammed device. Perhaps if batteries could be removed and placed into a special, cooled enclosure, it could work. Mrk
I'll buy that. Issue might be just as you point out. Is it safe or not? Rapid Charge heating is something to consider.
And you don't mind sitting on 60-70 liters of fuel, which is being detonated in a controlled manner a few thousand times a minute? The fire risk in batteries obviously exists, but with cars, you have the luxury of insulating the materials more effectively, as you are not constrained by the size of the container. Mrk
It is that controlled manner that makes me feel better about it. Gasoline has be be vaporized and compressed to get the energy out of it that a car uses. It's still flammable and explosive in the right circumstances, but I don't drive a 1970's Ford Pinto. I'm sure battery technology and safety will improve with time, but yes, at this point I feel safer in a gas powered car than I do putting a cell phone in my pocket. They have a long way to go to convince me to feel safe with a 1,200 plus pound one sitting in my car. Even if I am wrong. I don't want to drag this too far off topic, but since the article was about batteries, so are my thoughts.
