battery or ultra-/super-capacitor or 2-in1 as ultra-battery
« on: March 12, 2021, 11:17:08 PM »

2011 : https://cleantechnica.com/2011/05/11/cheaper-ultracapacitors-for-electric-vehicles/


 So, even though these supercapacitors initially cost $2,400 to $6,000 per kWh of energy storage, and the lithium ion batteries used for electric vehicles initially cost $500 to $1,000 per kWh, in the long term, supercapacitors may be cheaper or comparable.





2015 :  https://eepower.com/new-industry-products/10000-farad-graphene-supercapacitor/


Tesla recently announced a Super Factory to be built in Nevada, with a promise to get the price of lithium batteries down to $150 USD per kWh by 2020, our current cost estimated for this type of graphene base supercapacitor is about $100 per kWh today and we feel confident we should be able to cut this pricing in half by the end of 2015

2020 :
https://energystorageforum.com/news/sunvault-unveils-1000f-graphene-supercapacitor#:~:text=Monaghan%20compared%20the%20cost%20for,USD%20per%20kWh%20by%202020.


This technology represents a fierce competitor to lithium ion batteries and could potentially replace the lithium batteries in the future. Monaghan compared the cost for this type of graphene supercapacitor at $100 per kWh to Tesla’s target price for its batteries that will be produced at its GigaFactory at $150 USD per kWh by 2020.

Energy density of supercaps is still much lower than the energy density of Li batteries.

Also the leakage current is much higher. A car powered by supercaps would be without power after only a few weeks.

skywatcher,you gives the reazons for the development from the 2-in-1 solution :

a hybrid combination from capacitor advantages and battery advantages

by the australian CSIRO : Ultra(-caps)battery https://en.wikipedia.org/wiki/UltraBattery  at first with lead batteries

When UltraBattery and standard VRLA (used in a partial SoC regime) are compared in experimental conditions, UltraBattery has been shown to achieve about 13 times the capacity turnover of a standard absorbed glass matt VRLA battery.

A lead battery related + argument,is it not ? With other battery kind ,alternatively ?

Many other advantages !



Costs for lead battery charger,lithium battery charger ? total battery set costs per KWh generated/stored ?




Caps with 5-20 Wh/Kg
Batteries with up to 500+ Wh per Kg




But the published prices in the articles are per KWh,not Kg !

And e-storage is not only for cars important !

Kg or volume is then not such important like the storage incorporation in car bodies

Btw : the battery industry is planning " beyond lithium" !

Sincere
OCWL

www.kilowattlabs.com
Where such supercapacitors can become alternative to batteries !?
1 000 000 charge cycles !?

Why US20180076644,Waseem Ashraf Qureshi application " abandoned" ?
Better lab results  inventions ?
The publicated shop selling prices 1400€ per KWh  storage are "horrible expensive" compared conventional graphene capacitor or lithium battery based solutions !From selling price view !

Counter-argument :
1400 €/1 000 000 charge cycles a 1 KWh = 0,14 €cent/KWh or 0,0014 €/KWh storage costs


The net production costs from the Kilowattlabs supercapacitor ?The given 1 KWh density weight : 23 Kg


Which is the "conventional supercapacitor"-production/gross selling price per Kg ?
Gross-selling: alibaba example Dongguan City Gonghe Electronics

                          +- 62,5 US$/Kg for 500 thousands charge cycles
                                                       75 Wh storaged energy per Kg

                          +- 850 US$/KWh fob factory

                          In € and per KWh charge cycle same/similar like Kilowattlabs : 0,0014 €/KWh energy

                          by attention : KWL = online seller  shop price versus " Don..."  fob factory gross buy discount price


When 2011 the supercapacitor price range per KWh was 2000-6000 US$ and now +- 100 US$ ,probably 2030 such KWL-type caps for 750-500 US$/KWh (or less  ;) ) available !

For conventional private household,as energy storage,a graphene supercapacitor,with in average 100 000 charge cycles and average 150 US$/KWh endconsumer price would be the breakthrough


100 000 /365 days ~ 274 charge cycles per day /10 years ~ 27 charge cycles per day
                                                                                        20 years ~ 14 charge cycles per day

                                                                                        30 years ~  9 charge cycles per day

Enough !

"We are reducing the cost and complexity of the battery and at the same time increasing its range and performance," said Thomas Schmall, Volkswagen's Chief Technology Officer and responsible for battery production. The new standard battery, which will be installed across all brands in up to 80 percent of all electric cars the group by 2030, will reduce costs by up to 50 percent, according to the company. “On average, we will reduce the costs for battery systems to well below 100 euros per kilowatt hour.” This will make electric mobility affordable.

                    Energy density:            75wh/kg




https://patentauction.com/patent.php?nb=13385


2 Practical Demands and Current Situations of Energy Storage Applications


The popularization of large scale energy storage and high power energy storage require energy system have relatively high power density and relatively high energy density, moreover, long life and low cost that are similar with mechanic system are also required.


 United States Advanced Battery Consortium USABC and Department of Energy DOE have set up standard demands for hybrid vehicle auxiliary energy system that are working with power over 625W/kg lasting 10 second, with total energy of 7.5Wh/kg.


 Large scale energy storage ordinarily requires that the energy storage devices should reach about 4000 times in cyclic life, the cost should be less than 500 USD per kilowatt hours in near future, reach 125-250 per kilowatt hours in far future.

So it will become important to observe the development from this application

f.e. http://capacitorsciences.com/wp-content/uploads/2018/09/CSI-Executive-Summary.pdf


Capacitor Sciences was founded in 2014 and was acquired in 2016 by Blue Solutions, part of the Bollore Group (EPA: Bol). The Company’s molecular modeling and experimental results demonstrate the materials-based performance required to produce capacitive energy storage cells with a capacity of greater than 2.5 kWh/kg, ten times the specific energy of commercially available lithium ion batteries. The Company is now scaling up the production of its metadielectric materials for device development and testing. The Company plans to enter pilot production in 2020-2021 and engage in mass-market commercialization through corporate partnerships.


Capacitor Sciences has developed novel dielectric materials for energy storage devices with energy and power densities of more than 10X of lithium ion batteries at a significantly lower price


                                               

The Economics ( 2017 !) : Market Leading Price-Performance for All Segments


The available energy storage market forecasts assume high cost per kWh and, consequently, a limited market penetration. According to Bloomberg New Energy Finance, the average price of battery packs for Electric Vehicles (EVs) is now under $200/kWh but still needs to decrease to under $100/kWh to achieve mass-market penetration.


Capacitor Sciences intends to deliver energy storage modules for product integration at $50/kWh for EVs to reach price-performance parity with internal combustion engines and for the price of stationary storage of electricity not to exceed $0.01/kWh per cycle





https://patents.justia.com/assignee/capacitor-sciences-incorporated


https://patents.justia.com/patent/10597407


The energy storage capacity U is determined by the dielectric constant κ, the area A, and the breakdown field Ebd. By appropriate engineering, a capacitor or capacitor bank may be designed to have any desired energy storage capacity U.


 By way of example, and not by way of limitation, given the above ranges for the dielectric constant κ, electrode area A, and breakdown field Ebd a capacitor in accordance with aspects of the present disclosure may have an energy storage capacity U ranging from about 500 Joules to about 2×10v16 Joules.

For a dielectric constant κ ranging, e.g., from about 100 to about 1,000,000 and constant breakdown field Ebd between, e.g., about 0.1 and 0.5 V/nm, a capacitor of the type described herein may have a specific energy capacity per unit mass ranging from about 10 W·h/kg up to about 100,000 W·h/kg, though implementations are not so limited.

Upps,next barrier  8)  fallen :  November 9,2020


https://kilowattlabs.com/


https://kilowattlabs.com/news/kilowatt-labs-announces-development-of-solid-state-supercap-cellsnovember-9-2020/


 The prototype has an energy density of  450 Wh/kg, and can be formed into any shape and operate as supercap storage.

Compared #3 their commercial energy/weight ratio :


The net production costs from the Kilowattlabs supercapacitor ? The given 1 KWh density weight : 23 Kg 


                                                         = 43,5 Wh/Kg

                                How many charge cycles life-time now their 450 Wh/Kg supercap ( in prototype stage ! )?


                                                         too low the specific energy ?


https://f.hubspotusercontent00.net/hubfs/1188159/02-SMT-170502-1L-Data%20Sheet.pdf?__hstc=107776733.ac37128e134de159c1a46baaf7a68046.1622287159543.1622287159543.1622287159543.1&__hssc=107776733.1.1622287159543&__hsfp=2351239738&hsCtaTracking=ac33db76-6df8-4824-99f4-d39ee521a566%7Ca6b29eeb-9205-432a-b04a-54201681114d


                                                           specific energy : 4 Wh/Kg  :P

https://firstgraphene.net/new-graphene-supercapacitor-materials-offer-fast-charging-for-electric-vehicles/


Conventional activated carbon has a gravimetric capacitance of 50-150 Farads per gram, whereas laboratory trials show that these new graphene materials demonstrate a gravimetric capacitance of up to 500 Farads per gram.







We see here two types of supercapacitor https://patentauction.com/patent.php?nb=13385


                                                                 Version A


Applied in high power energy storage area, the most significant advantage of this patented technology is that the cost is far less than that of symmetric supercapacitor; it is only $20USD/kilowatt in power cost, about one third that of symmetric supercapacitor according to energy density, and one fifth when according to energy density. When its power density is above 1kW/kg that is more than 2-3 times than nickel-carbon supercapacitor battery, its energy density reached about 10Wh/kg; meeting for most high power requirements; cycling life is above 100 thousands, similar with that of symmetric supercapacitor; it endure charged and discharged 100% in depth, working rang is -20 to +60 degrees Celsius with good low temperature character; using aqueous electrolyte and green materials, it has no risk of fire and problem of environmental contamination.

                                                             means 20 USD/Kg




                                                                  Version B

According to the same principle, designed in form of lower power density but higher energy density, the energetic form of the innovative hybrid supercapacitor can be 10Wh/kg-20Wh/kg in energy density, cycling life above 10 000 cycles, with cost lower than $125 USD per kilowatt-hour, that reached far period target for large scale energy storage applications, be able to be used for renewable energy sources such as wind energy and solar energy.


 means               125 USD / ( 1000 Wh / 15 Wh average )  = 1,875 USD/Kg 8)  ,not 1875 USD but     < 2 US$/Kg  :o




        mass  production price ! Not endconsumer ! 2 US$/Kg is "simple lead battery" mass production price range !




                        20 US$/Kg  for  100 000 charge cycles           or                  2 US$/Kg   for   10 000 charge cycles




                                                =   per charge cycle the same production price calculation


                                                =   per 1000 charge cycles   0,2 US$       or   20 cents


                                                     future benchmark for capacitors and batteries




                                                =   per         charge cycle     0,0002 USD or   0,02 cent

                                                https://www.greencarcongress.com/2020/02/20200220-attia.html
                                                                   
                                                                            Are we soon here ?

                                               =   per          charge cycle     0,0001 USD or   0,01 cent




                                               https://www.thedrive.com/news/3208/uc-irvine-accidentally-invents-a-battery-that-lasts-forever




Let’s go conservative and say the average laptop battery lasts for 1,000 charge cycles, its capacity noticeably diminished after about two years. If that laptop had UCI's nanobattery it would easily last for 400 years (if 1,000 cycles = two years, 200,000 cycles = 400 years). That’s long enough for that laptop to share a name with, but be far less useful than, an actual brick. If UCI can apply its findings to commercial uses, there’s a revolution coming throughout the electronic landscape.




                       100 000 charge cycles -by the above calculation = 200 years is farly enough,is it not ? ;D  Danach schau ma moi ! ::)

 


                        10 000 charge cycles - by the above calculation = 20 years  is farly enough to overbridge all actually granted

                                  technical patent grant term max. = 20 years
