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 ?

                                                           specific energy : 4 Wh/Kg

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   ,not 1875 USD but     < 2 US$/Kg 




        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

                                                                            Are we soon here ?

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

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 ?   Danach schau ma moi !




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


                                   capacitor and battery patents temporal !

                                     but "ONLY 10 000 charge cycles ( for 2 Mio miles )" ! Wh/l or Wh/Kg ?









                                  technical patent grant term max. = 20 years


                                  utility model               term max. = 10 years


            the total energy storage industry GLOBAL  now to see under/by "open source" conditioning !
