Graphene.
1. Graphene batteries have higher specific energy, faster charging speed and better safety; lithium battery electric vehicles have the disadvantages of high cost and poor safety;
2. The lifespan of graphene batteries is also relatively long; the lifespan of lithium battery electric vehicles is short.
3. Graphene batteries also have great development potential, while lithium battery electric vehicles do not have much development potential.
Graphene batteries are good.
1. Lifespan: The specific energy value of a state-of-the-art lithium battery is 180wh/kg, while the specific energy of a graphene battery exceeds 600wh/kg. This means graphene batteries can store more electricity. Graphene lasts twice as longtime than lithium batteries and is also more resistant to high temperatures than lithium batteries.
2. Safety: The biggest disadvantage of lithium batteries is their poor safety. Although the probability of explosion is low, it is very dangerous as long as there is the possibility of explosion. In comparison, graphene batteries are safer. Compared with lithium batteries, graphene batteries with the same capacity are cheaper, about 2/3 of the price of lithium batteries.
3. Battery life: In the two specifications of 48V26AH graphene battery and 48V24AH lithium battery, the life of 48V26AH graphene battery is longer than that of 48V24AH lithium battery.
