I remember... ~20 years ago(?) hearing about graphene (and carbon nano-tubes, for that mater) and how it would 'revolutionize' everything that used or produced electricity and heat. The current hype surrounding 'solid state batteries' seems to be following a similar story timeline, where we hear about an emerging technology that is decades away from actually being a part of our lives. I agree that 'someday' all of the incredible technologies that have been discovered in laboratories will come to fruition - there is no doubt about that. The question I am left with though is - 'Will it actually be within our lifetimes? That isnt cynicism, far from it. But what it will take to make that specific 'future technology' profitable in widespread use is for some motivating factor to emerge to justify dumping ungodly amounts of money into to developing a workable technology.

Just my opinion but I really believe that we haven't hit that over all close to perfect ebike yet, I would like to see a more compact ebike with 20 inch tires that has excellent adjustable suspension and comfortable seat with custom attachments for a trailer, a hidden rain top that can be used when needed to stay dry, saddle bags, pet carrier, room for a passenger, even an attachment that can turn into a stable reverse trike for older people that may need it. A snow kit, I could go on a bit more but sitting down with a think tank and really being next level and making it actually look incredible as well. The most comfortable compact customizable ebike ever made that can please just about everyone with multiple options.

Can you build a diy sodium ion ebike batt to test on your channel?

I've been hoping for a breakthrough in lithium-air for a long, long time now. That would be a true revolution and allow all sorts of applications that are not practical today.

It is not enough to want higher capacity batteries you need devises that need it, that will not function without it, would battery tech be where it is now if wasn't for cell phones and there like. I was a Tomorrows world guy loved it.

There are already ebikes with graphene batteries, they say they will be commercially available this year, let's hope it pans out.

paraphrasing thunderf00t here (i know he's a bit icky) but we are sitting at 200 Wh / kg, and for good reason: there's fuel and oxidiser in the same package in batteries. You need at least one atom to hold the charge, one atom to take the charge when it discharges, and you need to separate the two by something to stop it discharging on it's own. Also, you don't just need any kind of energy out, but electrical energy, which carries penalties on it's own. Battery technology is probably has as high specitic energy as it's going to get if you want to maintain safety, reliability, and charge-ability. Ten times increase in capacity would get you the same as termite! Same heat-capacity as water, same specific energy as termite, short circuit the thing and you have about 1000 degree C, perhaps not quite the melting point of steel, but hot enough to instantly ignite any nearby furniture just by convection, and if it gets extra atmospheric air it would get even hotter than that! i'm not one of those people who worry about spontaneous combustion near a button cell battery, but we have to consider worst case scenarios with this stuff

you nearly lost me at 9:49 but last twitter post i read say they will be out in 2028ish which is still a decade before i will have a bike ready for a customer so i can understand

What is the point of graphene ? I will only give a better power drained/capacity ratio, it can hardly increase the capacity itself.

They say that far less than 1% of proposed or studied battery technologies ever make it to market..Which rings true if you've been watching these technologies for decades..I'm not a techno optimist..All of our technologies have horrific consequences..Those consequences compound and multiply, until a tipping point is reached.Which is why every civilization to ever exist has broke down, collapsed and died..Our technology can only be temporary..I have advanced degrees in chemistry and biology, worked in sustainable development for well over a decade..Once you understand the way everything works, then you can understand the future. "All of our exalted technological progress, civilization for that matter, is comparable to an axe in the hand of a pathological criminal" Albert Einstein "Every human civilization to ever exist, has been a losing race, to discover remedies for the predicaments that they produce" "It's no measure of health, to be well adjusted, to a profoundly sick society" Krishnamurti While it's a miracle to be alive, I have zero faith in technology, and use it to be as self sufficient as possible..

let's talk about products when they're something to buy and build with. until then, zero interest. so much online is in a constant race to steal my attention, I'm skeptical of anything that isn't practical.
