PRESENTATION. "THE NEW GRAPHENE BATTERIES TECHNOLOGY"

FIRST)

GREETING: Good morning everyone, and thanks for coming.

OBJECTIVE: The aim of this short presentation is to tell you about our new graphene battery technology.

NEED: I´d like to start by asking a question. Why do we need a battery of graphene?
Well, as we all now, the lithium-ion batteries have Little autonomy so they can must be used in an all-electric car and recharging time is very long.
We need to implement a modern battery. Therefore, we have use the new graphene batteries.

PROBLEM: So, what is the problema of lithium ion batteries?
The problema is that they are weak and fill a large space in the vehicle, must be less heavy and have less recharging time.

DESING BRIEF: And tha bring me to our the design of the new graphene batteries.
Korean scientists have developed a fast to load and very light battery to solve the problema of old batteries in electric cars.

MATERIALS AND PROPERTIES: Now let´s move on to materials. What is a graphene battery? It is a next generation battery, this battery consist in a graphene. Graphene is a mineral capable of electrically charging and provide the energy stored in a circuit.
It´s a great innovation and a major technological breakthrough, not only for the automotive industry, but to all the technology in general.


SECOND)

I will continue talking about this new type of battery.

PARTS&FUNCTIONS: Okay, so now let´s see the main parts and functions of the graphene batteries.
As you can see on the screen, the battery is based on cells like conventional batteries. It consist of very small super-capacitors conected in parallel. This technology allows you recharged a battery in between 2 to 15 minutes reducing the time by 90%.

DIMENSIONS: The new batteries are lighter tan conventional. This batteries offer greater perfomance in the same space. One graphene battery take 60 liters space.

OPERATION:  Okay, now let´s move to the operation os the battery. How does it work?
The battery is recharged from the home network or any electrical mains.
Dpending on size it takes about 15 minutes for a complete charge. Afther recharging the battery operates at a constant yield until discharged. It can be recharges 10000 times without losing perfomance.

ADVANTAGES: And finally I would like to mention some advantages of the graphene batteries.
These batteries don´t pollute, reduce recharging time and hace a range far superior to lead and lithium-ion batteries.



A FEW QUESTIONS

1) ¿What are needed of a new type of cars because to protect environment?
2) ¿What are the problems with petrol and diesel engines of the currents cars?
3) ¿Which are the parameters of maximun speed, range, acceleration and emisions os new hrydro-x cars?
4) ¿What technology are based the hydro-x cars?
5) ¿What are the advantadges os new hydro-x cars?
6) ¿What is the power output and location of the fuel cell in this new hydro-x cars?
7) ¿Where the engine is located and where is this capacity output?
8) ¿Where the control unit function in this new hydro-x cars?
9) ¿Where the ultra-capacitor function and why located there in the vehicle?
10) ¿Where the hydrogen storage tank located and where is this capacity?
11) ¿Why are airpump needed in this vehicles?
12) ¿What are the hydro-x cars operations that work?

PRE-PRESENTATION WORK SCHEMATIC

Recharging the battery or its rapid change in seasons, is currently one of aspects to consider when you think of an electric car.
They have a lot of capacity, so I usually take time to load... Until you get graphene to their lives.

So say korean scientists who are working on a battery where a graphene supercapacitors are the protagonist.
In these prototypes has managed to store the same amount of energy in a lithium-ion battery, but with the advantage that charging and discharging occurs in secods, up to 10.000 cycles posible charges.

After this fast loading and also facilitate refueling, open the possibility to develop better systems forreuse of energy lost in braking, E.G cars.
