Since last year 3500mAh on a 18650 battery has been the top (or I have seen rewrap of 3500 Sanyo GA to 3600mAh, funny since the GA battery actually is a 3350/3400 battery). I know the focus has been on higher Amps, and such I understand things, high Amps do not go well with high capacity.
Still, is there any news about 18650 (and/or 26650) with higher capacity then 3500mAh and 5500mAh on the 26650?
Of course you have the soon one million mAh Ultrafire battery…but I’m talking about the more normal factories like Panasonic, Sony, Sanyo, LG, Samsung and so on. Not thinking about wrappers here like Efest, Basen, Keeppower etc etc
Or will the industry concentrate on higher and better Amps also this year?
We have the technology to make higher density thus higher capacity cells, the problem is lowering the costs of production to keep the watts/dollar ratio reasonable. Most 18650 are used to build packs where weight is not an issue, so instead of using higher capacity cells they just add more cells instead.
We may see a higher capacity battery come out towards the end of this year according to many manufacturer’s release schedule. They plan these things with a timeline about 5 years in advance. Partners will receive samples long before release.
