“………What it all boils down to is that BMZ developed what it calls ‘giga-cells’. They are named 3Tron and come in the 21700 format; 21mm diameter and 70mm height which is a lot bigger compared to the nowadays commonly used 18650 cells. The new 21700 cells offer, “60 percent more capacity while being able to use 400% more discharge current at the same time,” claims Sven Bauer, Managing Director of BMZ GmbH.
Thanks to a big increase in active cell material as well as the use of nickel-manganese-cobalt oxide, stronger conductors and high-quality materials, 3Tron increases the energy yield by 50 percent. The lower internal resistance produces 68 percent more output.
In producing the super cell, BMZ cooperates with the world’s leading cell manufacturer Sony. This company’s manufacturing expertise comes with the annual production of more than 300 million cells, says BMZ………”
Those are still too expensive, but pretty good when considering that they just became available. Remember how expensive the NCR18650B was a few years ago? It was insane, but now they go for about 1/3rd of that. Hopefully these do the same and end up costing around $3, which I think is entirely possible with cells coming out of Tesla’s Gigafactory’s. BMZ calls their battery factor a gigafactory too, but apparently is unaffiliated with Tesla. I think their prices will be good, but it’ll be hard to match the advantages of Tesla’s vertically integrated business. Competition is good though, and should drive up manufacturing efficiency and battery capacity.
ok applying my logic
the 21700 will become a household name like AA and aaa (yuck i hate aaa)
i think the general audience has matured to the point they are ready for a paradigm shift in there lives
we Here and in the Vaping world have held onto something for too long and it is time what we know and care about be taken away from us (can you handle that)
up to this point most consumers have never heard of an 18650 or 14500 because it was never meant for them 18650 have been around since 1991
it would be like giving a Light Saber to Jar Jar Binks
but the world is smarter and the chargers are better or the 21700 will be too big to leave in a pants pocket with loose change
i hope to see the 21700 in stores even Kmart soon
i am looking for the ’’That’s one small step for mankind, one giant leap for mankind.”
i have had fun for years ripping apart things for the**_ “Precious bounty” even did a Creative MuVo2 for the 4gb Microdrive _**
but now i only buy NEW TOP OF THE LINE Sanyo/Panasonic NCR18650B and at one point i paid $2,82 each for 50 (now they are hard to find at $4)
but i am trying to say i think 21700 will be come a household word sorry for my rant
Outside of the small group of flashlight enthusiasts, almost nobody has ever heard “18650” and I would be willing to bet about 0.0000001% of the world population knows what it is.
Now you think people will magically need something 10000x less common than an 18650??
Sorry, but no, this is never going to become as common as alkaline batteries. Even 18650 will never become as common as alkalines.
Ask your grandparents what an AA is and they will know, but not 18650 or 26650.
I think all the people in this thread need to get real and actually see what a huge minority they are and how rare 18650s are outside of their flashlight friends group.
Tesla’s got 20700 cells, now this Euro factory is making 21700s.
And isn’t the 3Tron name already copyrighted by one of our own forum members?
But riddle me this - why not make a better 26650, a format that already exists? If you take the 20700’s specs, scale it up to 26650, you’d have even more energy per cell.
Two answers. The engineers wanted this size. Nobody but the Chinese in the last 5 years have made 26650’s. On 20700/21700 standardization 20700 list a 20.3 mm diameter, 21700 list a 21 mm diameter, light junkie’s aren’t even going to notice the difference.
Here is a very interesting SDLE marketing report summary (as of Sep 2016) regarding the replacement of the 18650 format by 20650, 27000, and 21700. It’s a quick read and worth looking at. Lots of charts and graphics. Learned that LG will introduce a 21700 in Q2 2017.
This entire topic is about 20700 replacing 18650 which is why I clarified that it is 2017 and the fact that 18650s in laptops form the past is now irrelevant.
Therefore, it does not matter that 18650s used to be used in electronics because they are not today and will not be “replaced” by 20700.
Did you not read the topic title??
