Why hasn't graphene batteries replaced lithium batteries?

Why hasn't graphene batteries replaced lithium batteries as batteries for electric vehicles? The reason is that there are no graphene batteries. As long as the graphene battery is added, its advantage is that it can conduct heat and electricity without changing the battery. Let's expand the function of graphene battery a bit. Today's graphene batteries are essentially a mixture of lithium batteries and a small amount of graphene. Therefore, there are no graphene batteries at the root, only graphene-doped lithium batteries/lead-acid batteries, etc. Therefore, there are no graphene batteries at the root, only graphene-doped lithium batteries/lead-acid batteries, etc. Therefore, most studies are still exploring whether there is a way out for graphene to be used in lithium batteries. Graphene has many patents, but most of them are flexible devices such as semiconductor displays, and batteries are only a small part of them. But if you look closely, you will find that most patents only involve graphene three to four times. Do you know what this means? Just want to say that something can be added to this thing, just want to say, say forever. The battery benchmark company Panasonic (Panasonic) has even worse luck. In the next few years or ten years, what will happen is lithium batteries using new materials, perhaps graphene-based lithium batteries. It is now difficult to increase the capacity of lithium batteries. The first step in technological advancement is high and low temperature functions. For example, many lithium battery vehicles have reduced capacity during high temperatures in summer and low temperatures in winter, resulting in a decline in useful utilization. Large-capacity polymer lithium batteries are generally difficult to achieve current charging above 1C, the battery charging and heating time is short, the battery expansion rate is too large, and there are safety hazards. Can participate in graphene cooling, but the true end of graphene batteries still has a long way to go.
