AA Ni-MH battery

　　Is graphene AA Ni-MH battery fast charging technology expected to trigger industrial change?

　　In the field of consumer electronics, AA Ni-MH battery capacity and charging speed are eternal topics. Many manufacturers use fast charging technology and AA Ni-MH battery capacity as gimmicks for their products.

　　Currently, lithium batteries are most commonly used in this field. Lithium batteries were first commercialized in 1991 and have since become standard equipment for electronic equipment. But many people believe that this technology has reached its limit and hope to find alternative sources, so graphene batteries have entered people's attention. It is reported that graphene is extremely conductive and durable, and scientists are looking for various applications of this material.

　　Recently, Samsung Electronics' R&D department successfully synthesized a "graphene ball" that can be used to extend the AA Ni-MH battery life of lithium batteries and speed up their charging. Graphene ball material can increase AA Ni-MH battery capacity by 45% and charge five times faster.

　　Samsung said that if the existing lithium AA Ni-MH battery needs to be fully charged in one hour, then using this new technology, it can be shortened to 12 minutes, and the lithium AA Ni-MH battery using graphene balls can also maintain the temperature at 60 degrees Celsius, which is in line with the requirements for electric vehicles. Requirements.

　　Data show that graphene batteries are a new energy AA Ni-MH battery developed by utilizing the characteristics of lithium ions that shuttle rapidly and massively between the graphene surface and electrodes. The new AA Ni-MH battery reduces charging times from hours to less than a minute.

　　Seeing the application prospects of graphene, many countries have established graphene-related technology research and development centers in an attempt to commercialize graphene and then obtain potential application patents in industry, technology and electronics-related fields. The European Commission has designated graphene as a "future emerging flagship technology project" and formulated a special research and development plan, allocating 1 billion euros in funding over the next 10 years. The British government has also invested in the establishment of the National Graphene Institute (NGI), striving to make this material from the laboratory to the production line and market in the next few decades.

　　my country also has unique advantages in graphene research. From a production perspective, graphite, which is a raw material for graphene production, has abundant energy storage and is cheap in our country. In addition, mass production and large-scale production are the main factors hindering the large-scale commercialization of graphene.
