November 24, 20169 yr https://cyclingindustry.news/florida-scientists-create-battery-with-20-times-the-longevity-of-lithium-ion/ Posted this one online today. These don't always come to fruition, but looks promising for e-bike market.
November 24, 20169 yr https://cyclingindustry.news/florida-scientists-create-battery-with-20-times-the-longevity-of-lithium-ion/ These don't always come to fruition, I'd reword that regarding these "huge leaps": They never come to fruition. .
November 24, 20169 yr These "breakthroughs" always surface when they are looking for investment. I'll bet one of my testicles that it'll never make it to market, or even work in practice as the article claims.
November 24, 20169 yr So, a battery that last 20 times longer, could be 20 times smaller for the current ranges achievable?
November 24, 20169 yr These "breakthroughs" always surface when they are looking for investment. I'll bet one of my testicles that it'll never make it to market, or even work in practice as the article claims. Wouldn't that leave you with no testicles
November 24, 20169 yr Wouldn't that leave you with no testicles My granddad said that he knew a prisoner of war that used to do this during WW2. He would bet various parts of his anatomy and always lose the bet. Eventually, he managed to escape back to the fatherland. We're onto you Herr Lee!
November 24, 20169 yr We already have batteries that last 20 times longer: Lithium titanate. Every advantage seems to have a disadvantage attached to it.
November 24, 20169 yr Wouldn't that leave you with no testicles Just checked and I've still a complete set. Talking of balls, has anyone seen this advert doing the rounds on the telly at the moment? I thought it was a joke, but no, it's a genuine ad for a real product.
November 24, 20169 yr My favourite most hated phrase " 20 times smaller" please use real english. Get an avatar.
November 24, 20169 yr Trying too, I select an image, click on image but nothing happens. Well it's working now.
November 24, 20169 yr Trying too, I select an image, click on image but nothing happens. Is that because it's 20 tines too small.
November 24, 20169 yr Technical question, Is it a battery or something else? I read somewhere it's capacitors.. or was it ice cream cones?
November 24, 20169 yr So, a battery that last 20 times longer, could be 20 times smaller for the current ranges achievable? Na there's no mention of power density.
November 29, 20169 yr Battery leaps over horizon: "Arrrgghhh!!!! the Earth is flat!"... I thought Graphene was going to be the new wonder material for batteries!
November 29, 20169 yr I thought Graphene was going to be the new wonder material for batteries! That followed carbon nano tubes, which also got nowhere. Announcements of battery advances are like political manifestos, full of promise never to be realised. .
November 29, 20169 yr That followed carbon nano tubes, which also got nowhere. Announcements of battery advances are like political manifestos, full of promise never to be realised. . It takes longer for a new technology to make the transition from lab to mass production than is being assumed. Anyway nanocarbon tubes would be a species of graphene . We can assume that there will be improvements in energy density in future. Motors will not get much better,. they have already had 100 years of development, stronger magnets will make them a bit lighter , but that all. However there are plenty of other chemistries being explored. A completely out of the box concept is to use bottles of cryogenically cold air driving a motor. The energy density is surprisingly high.
November 29, 20169 yr It takes longer for a new technology to make the transition from lab to mass production than is being assumed. It certainly does, that's why we still start our vehicles with fundamentally two century old technology. So much for all the "great leaps forward" meanwhile, they've all involved problematic compromises. I've been watching the snail's pace of battery progress for many decades and I haven't got much longer left to see a real "giant leap". .

Sorry but you still start your vehicles with old technology because the companies making them make more profit than they would if they used modern technology. Don't believe me? Go ask Elon Musk...
November 30, 20169 yr Sorry but you still start your vehicles with old technology because the companies making them make more profit than they would if they used modern technology. Don't believe me? Go ask Elon Musk... I don't buy that, Elon Musk has a huge commercial bias shaping his views. If it was purely financial the makers of the hugely expensive luxury end cars would do different, but they don't. The fact is I know from all my motor industry connected years that the makers would love to get rid of the inconvenient lead-acid weight and bulk, but none of the new technologies measure up to all the demands in the same way. If one of them ever does, even if very expensive, it will go straight into cars at the expensive end of the market. . Edited November 30, 20169 yr by flecc
November 30, 20169 yr Look how long it took them to go from vented batteries which used to spew acid all through the engine bay to sealed gel type and yet the sealed gel type had been available in the maritime sector for years. A high discharge lithium battery is pretty easy to make but would cost a lot more than a lead acid battery and every penny counts when you are called Ford or GM.
