Hehe... Forgot about Sodium-ion... Wiki:
Battery-grade salts of sodium are cheap and abundant, much more so than those of lithium. This makes them a cost-effective alternative especially for applications where weight and energy density are of minor importance such as grid energy storage for renewable energy sources such as wind- and solar power.
i believe that iz the point of this thread, beyond saving space/easy reference.
This is promising. The scib battery has been around for awhile. Great at everything but capacity but sounds like they might have fixed that.
https://asia.nikkei.com/Business/Busine ... le-batteryTOKYO -- Leading Japanese manufacturers have teamed up with the government in a program to develop solid-state batteries, which are expected to power the electric vehicles of the future.
Kicking off in May, the program teams the Consortium for Lithium Ion Battery Technology and Evaluation Center, or Libtec, with companies like Toyota Motor and Panasonic to develop the highly efficient battery.
The program is aimed at returning Japanese manufacturers to the forefront of automotive battery technology, as international rivals have eroded their once dominant position in the field.
....To support development, Japan's Ministry of Economy, Trade and Industry will provide 1.6 billion yen ($14 million) in funding to Libtec, a research body whose members include Asahi Kasei and Toray Industries.
Toyota Motor, Nissan Motor, Honda Motor, Panasonic and battery maker GS Yuasa will also participate in development.
I think its about right. They have the team and the equipment. The trick is to work on both energy density and energy vs cost. If they have been working on that for about 10 years and grown to the size they are I think the numbers are believable.Chalo wrote: ↑Jun 09, 2018 5:53 pmhttps://electrek.co/2018/06/09/tesla-ba ... oughs/amp/
They're saying $100/kWh of cells within the year, $100/kWh for the whole pack within the following year. Here's hoping.
Hehe... Gotta broom handy?
In 1898, delegates from across the globe gathered in New York City for the world’s first international urban planning conference. One topic dominated the discussion. It was not housing, land use, economic development, or infrastructure. The delegates were driven to desperation by horse manure.
The horse was no newcomer on the urban scene. But by the late 1800s, the problem of horse pollution had reached unprecedented heights. The growth in the horse population was outstripping even the rapid rise in the number of human city dwellers. American cities were drowning in horse manure as well as other unpleasant byproducts of the era’s predominant mode of transportation: urine, flies, congestion, carcasses, and traffic accidents. Widespread cruelty to horses was a form of environmental degradation as well.
The situation seemed dire. In 1894, the Times of London estimated that by 1950 every street in the city would be buried nine feet deep in horse manure. One New York prognosticator of the 1890s concluded that by 1930 the horse droppings would rise to Manhattan’s third-story windows. A public health and sanitation crisis of almost unimaginable dimensions loomed.
Snip........For starters, while power density (the amount of power output per unit of weight) is off the charts, energy density doesn't compete with lithium. An ultra-capacitor will only hold about 25 percent of the energy per unit of weight that a lithium battery can manage, so a car battery with the same sized ultra-capacitor would have only a quarter the range.
Secondly, capacitors suck at long-term energy storage. Leave your car charged up in your garage, and you could expect to leak around 10-20 percent of your energy out each day.
The Nawa team believes that the full potential of the ultra-capacitor, at least in the EV space, becomes unlocked when it's combined with a lithium battery.
A hybrid lithium/carbon battery system could offer the best of both worlds – long-range continuous driving and long-term power storage thanks to the lithium unit, plus ultra-fast partial charging and extreme power output thanks to the ultra-capacitor.
This kind of hybrid system has another hidden advantage: regenerative braking would become about 450 percent better at recouping energy. Current re-gen systems are forced to throw away the vast majority of energy generated back through the wheels under braking simply because lithium charges so slowly that there's nowhere to put it all.
"Most of the energy in regenerative braking is lost as heat, maybe 80 percent," says Grape. "Perhaps 20 percent is recouped. The electric motors are very efficient at generating that power, but the battery just can't accept the charge rate. If you combine our technology with the lithium battery, we can accept up to 90 percent of that energy."
In a regular driving situation, that could handily extend your battery range. In an electric race car, this kind of system would be even more effective, storing almost all of your braking energy coming into a corner, and then pumping it back out at a massive rate for huge acceleration out of the turn.
"For example, let's take Formula E racing," says Grape. "If you look at the batteries they have on those cars, we've done a simulation using data from a co-operation partner of ours, and we've analyzed it. When you combine our technology with the lithium battery, we could reduce the size and weight of the battery pack from 300 kg (661 lb) to about 200 kg (441 lb) – and you'd have a longer driving distance as well, because we're much more efficient."..............snip
