Lithium batteries and supercapacitors are two very potential and widely used energy storage devices. Their principles, characteristics, and application scope are very different, and each has its own strengths. Since its inception, graphene has been regarded as a revolutionary energy storage material because of its strong electrical conductivity. Just imagine, if supercapacitors, lithium batteries and graphene are combined, what kind of sparks will collide?
Charge for 5 minutes! 500 kilometers of battery life! Graphene batteries make power worry-free!
Graphene, a single-atom-layer planar film composed of carbon atoms, has a thickness of only 0.34 nanometers, and the thickness of the single-layer is equivalent to one-hundred-thousandth of the diameter of a hair. It is the thinnest and hardest nanomaterial known in the world, with good light transmittance and foldable. Because there is only one layer of atoms, and the movement of electrons is restricted to a single plane, graphene also has entirely new electrical properties. Graphene is the most conductive material in the world. The graphene composite conductive powder is added to the traditional lithium battery for mobile phones, which improves the rate of charge-discharge performance and cycle life of the battery.
However, the technical difficulties of preparation are the biggest obstacles hindering graphene from realizing its potential value.“ Roadblock. At present, most graphene battery technologies are still in the experimental stage of research and development. Do we really have to wait a long time?
A few days ago, Polycarbon Power, a wholly-owned subsidiary of Zhuhai Polycarbon Composites Co., Ltd., developed a real commercial graphene battery product, which will pull the graphene battery in the laboratory stage into the battery market in one fell swoop and successfully solve the existing problems. The problem of unstable power battery, slow charging and low capacity.
Zhuhai Polycarbon adopts a comprehensive performance balance design idea, cleverly introduces a new graphene-based composite carbon material into the positive and negative electrodes of the capacitor battery, and combines ordinary supercapacitors with high-energy batteries to develop a new type of ultra-high performance battery.
The first graphene battery will first be used in electric vehicle batteries. It is expected to meet users at the end of this year or early next year. In the second half of next year, commercial graphene batteries used in the field of mobile phone batteries will also meet with you. At that time, mobile phone battery life, fast charging ability and safety problems of the battery can be solved 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. These three batteries have their own advantages and disadvantages, but car buyers can choose different batteries according to different advantages and disadvantages. And there is another kind of battery, the graphene battery, which is a completely subversive creation, and at the same time, it can avoid the spontaneous combustion of a Tesla car battery.
Polycarbon Power has mastered the preparation technology of graphene batteries. By adding graphene to the positive and negative materials of lithium batteries, the internal resistance of the battery is reduced, so as to achieve high-rate fast charging and fast discharging and greatly improve the cycle life of the battery. At the same time, the performance of the battery to withstand high and low temperatures is also improved. This is the core technology of Polycarbon Power, which cannot be replicated by other companies. The popularity of graphene batteries will be a leap for electric vehicles. Once graphene batteries are applied to electric vehicles, it will be a subversive change to the entire automotive industry.
