相关超级电容器、锂电池和石墨烯电池对比分析

而超级电容器是两种潜力巨大、应用广泛的储能装置。它们的原理、特点和适用范围各不相同，各有千秋。从一开始，石墨烯就因其强大的导电性而被誉为革命性的储能材料。

5分钟充电！ 500公里范围！石墨烯电池供电无忧！

Graphene is a flat monoatomic film composed of carbon atoms. It is only 0.34 nanometers thick. One layer is 150,000 times the diameter of a human hair. It is currently the thinnest and strongest nanomaterial known in the world, with good light transmittance and folding ability. Because there is only one layer of atoms and the electrons are confined to one plane, graphene also has brand new electrical properties. Graphene is the most conductive material in the world. The graphene composite conductive powder is added to the traditional mobile phone lithium battery to improve the battery’s charge and discharge performance and cycle life.

然而，制备过程中的技术难点是实现石墨烯潜力的最大障碍。目前，大多数石墨烯电池技术仍处于实验开发阶段。我们真的要等很久吗？

近日，珠海聚碳复合材料有限公司全资子公司聚碳动力研发出真正商用的石墨烯电池产品，将实验室阶段的石墨烯电池带入电池市场，成功解决了石墨烯电池的难题. 现有供电电池不稳定，充电速度慢，容量低。

珠海聚碳采用综合性能平衡的设计理念，巧妙地将新型石墨烯基复合碳材料引入电容电池正负极，将普通超级电容器与高能电池相结合，开发出新型超高性能电池.

首先，石墨烯电池将首先应用于电动汽车电池。预计他们将能够在今年年底或明年初与用户见面。明年下半年，手机电池应用领域的商用石墨烯电池也将与你相见。届时，手机电池续航快充能力和安全问题可以一一解决。

A staff member of Zhuhai Polycarbon Composite Materials Co., Ltd. introduced that lithium iron phosphate batteries and lithium manganese acid batteries are common electric vehicle batteries on the market. These three kinds of batteries have their pros and cons, but car buyers can choose different batteries according to their pros and cons. There is also a graphene battery, which is a breakthrough innovation that can prevent spontaneous combustion like Tesla’s battery.

Polycarbon Power has mastered the preparation technology of graphene batteries. Adding graphene to the positive electrode material and the positive electrode material of the lithium battery reduces the internal resistance of the battery, thereby realizing high-speed and rapid charging and discharging, and greatly improving the cycle life of the battery. It also improves the performance of the battery to withstand high and low temperatures. This is the core technology of Polycarbon Power, which cannot be copied by other companies. The popularity of graphene batteries will be a leap for electric vehicles. Once graphene batteries are applied to electric vehicles, they will have disruptive changes to the entire automotive industry.
