Comparison of super capacitors, lithium batteries and graphene batteries

Lithium batteries and super capacitors are two very potential and widely used energy storage devices. Their principles, characteristics, and application range are very different and have their own strengths. Since its inception, graphene has been regarded as a revolutionary energy storage material because of its strong electrical conductivity. Imagine, if you combine the super capacitor, lithium battery and graphene, what kind of spark will it collide?

Charge for 5 minutes! Endurance 500km! Graphene batteries keep power at ease!

Graphene, which is composed of carbon atoms in a single atomic layer thin film, the thickness of only 0.34 nm, single layer thickness is equivalent to one over one hundred and fifty thousand of the diameter of a human hair. Is known in the world the most thin, the hardest nanomaterials, pervious to light and can fold. Because there is only one layer of atoms, the motion of electrons is confined to a plane, and graphene also has new electrical properties. Graphene is the most conductive material in the world. It has added graphene composite conductive powder to the traditional mobile phone lithium battery, which improves the battery's rate charge and discharge performance and cycle life.

Preparation of technical problems, however, is hampering the graphene biggest "obstacle" live up to its potential value. At present, most of the graphene battery research and development of technology is still in the experimental stage, we really have to wait a long time?

Recently, the Zhuhai carbon composite material co., LTD., a wholly owned subsidiary, gathering carbon power has the real meaning of the development of a graphene battery commercial products, one will be at the laboratory stage of graphene battery into battery market, successfully solved the existing charging power battery is not stable, the problem of slow, low capacity.

Zhuhai Polycarbon has adopted a comprehensive performance balance design idea, and skillfully introduced a new graphene-based composite carbon material into the positive and negative poles of a capacitor battery, and integrated an ordinary super capacitor with a high-energy battery to develop a new ultra-high performance battery.

First graphene batteries will be firstly applied in electric vehicle batteries, is expected by the end of this year or early next year will be able to meet with the user, in the second half of next year, applied in the field of mobile phone battery commercial graphene cells will also meet with all of you, at that time, mobile phone battery life, quick charge capacity and safety issues can be resolved one by one.

The staff of Zhuhai Polycarbon Composite Materials Co., Ltd. said that at present, the common electric vehicle batteries on the market are lithium iron phosphate batteries, ternary lithium batteries and lithium manganate batteries. The three kinds of cells each have advantages and disadvantages, but buyers can choose according to different advantages and disadvantages of different batteries. And there is a battery, is the graphene battery, is completely subvert our creation, at the same time can be avoided as similar to the Tesla car battery incidents of spontaneous combustion.

Carbon dynamic had mastered the preparation technology of graphene battery anode materials in lithium batteries are adding graphene, reduce the battery internal resistance, in order to achieve quick high-magnification charge fast discharge and significantly improve the cycle life of the battery. At the same time also increased tolerance of high and low temperature performance of the battery. This is the core of the carbon dynamic technology, and other businesses can't duplicate. The popularity of graphene batteries will be a leap in electric cars, once the graphene batteries used in electric cars, on the whole auto industry will be disruptive change.

The core technology

Mystery lies in its core technology has taken a comprehensive performance balance design ideas, cleverly introduce new graphene composite carbon material capacitor anode, the batteries are realized the ordinary super capacitor combined with high-energy battery as a whole, and the excellent properties of both general super capacitor and battery.

Application

Graphene all-carbon capacitor battery is a new all-round power source. It can solve the problem of electric vehicle power, and can also be applied in surface ships,specials, drones,specials andspecial. In particular, its unique safety performance will have a profound impact on the development of the electric vehicle industry. This product combines the energy density of lithium-ion battery and the power density of super capacitor. According to the new national standard, the cycle life is more than 4,000 times, and the operating temperature ranges from minus 30 degrees Celsius to minus 70 degrees Celsius. On the basis of ensuring a certain driving range, high current fast charging and long cycle life can be realized.

Technological breakthroughs

New graphene full carbon capacity battery capacity is big, the advantages of the electrical energy into chemical energy, and then released into electricity, its energy density is more than the most top of lithium ion battery, power density is close to super capacitor, realized the battery and the traditional capacitance on structure and, realize the advantages of battery and capacitor both.

Performance advantage

Safe and stable, the new graphene polycarbon capacitor battery, after being fully charged, is shot with a nail gun, so that it is short-circuited, and there is no reaction; if it is placed on a fire, it will not explode.

Fast charging; Graphene carbon batteries, 10 c large current charging are available, and single block on a full charge as long as six minutes, in series with the hundreds of pieces of charging, 10 minutes can reach more than 95%.

The power density is high, up to 200W/KG~1000W/KG, which is equivalent to more than three times that of lithium batteries.

Cryogenic properties is good, can work in an environment of 30 ℃ below zero centigrade.
