New battery technology

[Atmosphere]

Just been reading about Li-S battery technology

Sounds interesting if it all comes off - or is it another Lithium Air ?

Lithium Sulfur Batteries

Hi Had there tec guys in about 6 months ago They are only down the road from us They can only match the size and weight we have now from our currant supplier It will be 3 years before the can reach the targets for smaller batteries in mass production If that

The Cycle Show before last, they came round touting their wares telling us that it was imminent. There was something that made them less desirable, but I can't remember what- maybe discharge rates. Wisper had some sort of partnership arrangement with them. If you look at their website, there's loads of news about agreements and associations, but precious little about actually making any batteries. I'm sure something will eventually come from all their research, but it won't be soon.

Just what do you put in your batteries Frank? Are they any good for raisin the life of the battery pack?

Was reading on electricbike.com THE NEXT EBIKE BATTERY Linimnc0o2/NMC lithium-Nickel-Mangenese-cobalt-oxide, claim to have a high c rate,

Hamster Oxide anode / Banana Sulphate cathode is going to be the next big thing. Batteries of less than 1 cubic millimetre, under 1 gramme, 5KWh, full charge in 20 milliseconds. They are due to become available last week.

this could could happen in our life time:
NASA’s cold fusion tech could put a nuclear reactor in every home, car, and plane | ExtremeTech

This is an hydrogen/nickel fusion battery, safe and clean.

Hi
tillson

Just feeling Fruity

I was busy in the workshop in fact just finished Building The controller and motor for our 50 MPH 60 volt Kit NO pedalling


Building the battery in the week when all the parts arrive 15 AH 66 volt weight 6 kilos

All cold fusion announcements are fantasy, often with names like NASA, MIT etc associated to try to give credibility. There has never been a trace of evidence that cold fusion will ever be possible.

This compound cathode mix has been around for a long time, and Sony have developed the same with chrome as well. Most of the additions are to assist with control of the cobalt element which, although a good cathode material, has formerly caused many fires when used in isolation.

Of all the elements, the best cathode material by far is iron, but it's proved stubbornly difficult to use with full effectiveness. The lithium iron phosphate batteries (LiFePO4) have been the only ones achieved to date, improving battery life but gaining bulk and weight, not ideal factors for e-bikes.

dilithium is the new technology in by e-bike battery. Buy once, never needs recharging.

Then why did the Star Trek crew have to search for new dilithium crystals?

A bit like Nuclear fusion new battery technology always appears further away than it seems. Key thing most people and businesses want would be to have a reliable technology which does not cost as much money. However prices seem to remain the same or go up. However it is always good to hear of potential developments

Dave,those guys made big claims....I think it comes under the heading of 'talk is cheap'....from memory I thought the big problem was cycle life,maybe only 50 recharges....they used those batteries in EPIRB yacht distress beacons,but they only need to be used perhaps once!!!
KudosDave

'....from memory I thought the big problem was cycle life,maybe only 50 recharges....

That has been their problem. The difficulty is that the Li.S cells react with the electrolyte causing irreversible loss of the active sulphur through the polysulphides disolving. One research body claimed they'd solved that with solid electrolyte but the electrolyte conductivity was low.

The potential is very attractive though, high density/capacity with very low weight and bulk, both ideal for e-transport of any kind and especially e-bikes. However, the difficulties with using sulphur for optimum benefit appear to be as intransigent as those with iron.

I've heard of these..... these batteries should work well the latest motors incorporating Flux Capacitor technology, originally invented back in the mid 80's by a Doctor Emmett Brown.
Fitted to the latest ultra light frames, made from unobtainium, it should make a fantastic ebike.

Pah; yesterday's tech - you need a nice little ZPM, you do.

Scotty couldn't provide Uhura's Rampant Rabbit with enough power, so they had to find an alternative source

as long as it dont go over the legal limit of 15 mph
