What are the advantages and disadvantages of graphene batteries?

The advantages and disadvantages of graphene batteries: 1. The power storage capacity is three times that of the best products on the market. The specific energy value of a lithium battery (whichever is the most advanced) is 180 wh/kg, while the specific energy of a graphene battery exceeds 600 wh/kg. 2. An electric vehicle powered by this battery can travel up to 1,000 kilometers, and its charging time is less than 8 minutes. 3. Long service life. Its service life is four times that of traditional hydrogenated batteries and twice that of lithium batteries. 4. Light weight. The characteristics of graphene make the weight of the battery can be reduced to half of the traditional battery, which can improve the efficiency of the machine loaded with the battery. 5. Low cost. The company that processes this battery says that its cost will be 77% lower than that of lithium batteries. High stability, long battery life, fast charging speed; Disadvantages: Traditional conductive carbon/graphite is very cheap, and they are sold per ton, while graphene is too expensive. The price of thousands of gram per gram, this is not the average company can afford. A few years ago, the price of graphene was as high as 5,000 yuan per gram, far exceeding the price of gold, and ordinary consumers could not bear it.
