#272 - Super second generation three-dimensional graphene supercapacitor!
Having said that, the projection screen behind Gao Nian displayed the performance parameter list of the second-generation three-dimensional graphene supercapacitor.
Next to this parameter list was the parameter list of the first-generation three-dimensional graphene supercapacitor for comparison, letting people know how strong it was.
Among them, the performance parameters of this second-generation three-dimensional graphene supercapacitor did not improve much compared to the previous generation in some aspects.
Some parameter performances even decreased, but some key parameter performances improved quite astonishingly, making people ecstatic.
For example, the most concerning aspect was the energy density, which had a significant increase compared to the first-generation three-dimensional graphene supercapacitor's 40Wh/kg.
Because the display showed that its energy density had reached an astonishing 155Wh/kg!
Seeing this amazing energy density, many people who understood the battery industry immediately erupted in an uproar, their eyes wide open as if they had seen an alien.
Because this energy density reaching 155Wh/kg was not a simple number.
The electric bikes commonly seen on the road have six lead-acid batteries or five lead-acid batteries. Among them, six lead-acid batteries, when driving on flat ground and in the case of a new bike, have a range of 60 kilometers.
As for electric bikes with five batteries, the range is 50 kilometers, basically achieving a level of 10 kilometers per battery.
Of course, some bikes may have a lower or higher range.
After all, electric bikes vary in range depending on motor power, electronic control systems, and rider weight.
However, the difference is not too significant, so this data is still very representative, and the energy density of these lead-acid batteries is between 40Wh/kg and 50Wh/kg.
At this time, the energy density of the second-generation three-dimensional graphene supercapacitor is an astonishing 155Wh/kg, which is equivalent to one battery being equal to three previous batteries!
In other words, if the battery weight remains the same, then after replacing it with a three-dimensional graphene supercapacitor, the range of the electric bike will triple!
Originally, a full charge could only run 50 kilometers or 60 kilometers, but now it can run 150 kilometers or 180 kilometers, which is a revolutionary change for electric bikes.
After all, the distance between one city and another is generally only 100 kilometers to 200 kilometers.
At this time, you can completely ride an electric bike to another city, achieving the performance that only motorcycles could achieve.
As for journeys over 200 kilometers, the range is still a little short, and there is no need to worry about the problem of needing to charge halfway.
Because the three-dimensional graphene supercapacitor, as a supercapacitor, its biggest advantage is its super-fast charging and discharging speed.
Relying on the advantages of fast charging and discharging, it can be fully charged in just a few seconds to a few minutes at most, so it is possible to travel all over the country with an electric bike.
Of course, Geek Technology Company does not plan to develop and sell two-wheeled electric bikes or three-wheeled small trucks.
After all, the technical content of this thing is too low, and a low barrier to entry will lead to considerable competitive pressure in the future.
Therefore, Geek Technology Company will only sell the second-generation three-dimensional graphene supercapacitor and will not develop and sell two-wheeled electric vehicles and three-wheeled small trucks.
According to the introduction on the projection screen, there is a second-generation three-dimensional graphene supercapacitor specifically designed for electric bikes.
The size and specifications of this second-generation three-dimensional graphene supercapacitor are the same as traditional electric bike lead-acid batteries.
The output voltage of its built-in supercapacitor management system is also 12V DC.
Because Gao Nian's words were too applause-worthy.
Speaking of which, whether in China or overseas, there is actually a problem called insufficient parking spaces.
Places with car parking spaces are often not the economically prosperous centers, but the marginal corners of the city.
Places without parking spaces are often the economically prosperous centers, and it is really difficult to find a car parking space when you drive a car.
Even in places with a lot of people, such as farmers' markets, it is difficult to drive normally because there are too many people.
Under such circumstances, if many people are not going to a distant place, they either walk directly or can only buy an electric bike to solve the problem.
Therefore, electric bikes are too common in many countries, especially in China, and they are simply a grocery shopping artifact.
Therefore, it is very common for a family to have an electric bike, and it is not uncommon for families to have two or three electric bikes, which shows the popularity of electric bikes.
But if you want to use an electric bike, you have to complain about the two major shortcomings of electric bikes. These two major shortcomings are the problem of too short range and the problem of short battery life.
The batteries of current electric bikes are often made of recycled materials, and the normal service life of this type of battery is only one year.
After one year, the range will drop sharply, so after one year, many people's electric bikes will often replace new batteries because they cannot bear the drop in range.
At this time, Geek Technology Company has also launched a second-generation three-dimensional graphene supercapacitor that is compatible with electric bikes.
Directly increasing the range of electric bikes from 50 kilometers or 60 kilometers to 150 kilometers or 180 kilometers is simply a savior for everyone.
And the most satisfying thing is that the charging and discharging times of this second-generation supercapacitor have reached more than one hundred thousand times.
This also means that after you buy a second-generation three-dimensional graphene supercapacitor, you can still use it for decades,
and then use it as a family heirloom for your descendants.
Of course, this is actually just a joke.
Although the charging and discharging times of the second-generation three-dimensional graphene supercapacitor can reach more than one hundred thousand times,
in fact, as time passes, the performance of the second-generation three-dimensional graphene supercapacitor will gradually decrease, and the failure probability will increase linearly.
Because this second-generation three-dimensional graphene supercapacitor is actually composed of two parts, one part is the three-dimensional graphene supercapacitor.
The other part is the power management system, which mainly functions to regulate voltage and stabilize voltage input and output.
And the thing with the shortest lifespan or the easiest to break is this power management system.
Therefore, although the charging and discharging times of the supercapacitor are as high as one million times, theoretically there is no problem in using it for decades, but in fact, considering the shortest board problem of the barrel theory, it is impossible to reach such a high number of times, which ultimately leads to the usable lifespan not being so high.
After all, nothing will not age, and the ubiquitous oxygen in this world is the world's largest decaying agent.
Therefore, according to the suggestion given by Geek Technology Company, the maximum service life is 10 years, and it is recommended to replace it directly after 10 years.
