Graphene batteries and lithium batteries each have their own advantages and disadvantages, and here are some of their key features:
Graphene batteries
Pros:
Long life: Graphene batteries have a long cycle life, about 800-1000 times.
High safety: Graphene batteries are not easy to deflagrate and have high safety.
Fast charging: Graphene batteries charge faster, for example, GAC Aion's graphene batteries can charge up to 80% in 8 minutes.
Cons:
High cost: Due to the high cost of high-purity graphene**, the cost of graphene batteries is much higher than that of lithium batteries.
Difficult to prepare: It is very difficult to strip graphene from graphite.
Lower energy density: Compared to lithium batteries, graphene batteries have a lower energy density.
Lithium batteries
Pros:
High energy density: The energy density of lithium batteries is as high as 200 260wh g, which is much higher than that of graphene batteries.
Mature manufacturing technology and industrial chain: The manufacturing technology of lithium batteries is mature and the industrial chain is perfect, which can achieve large-scale production.
Cons:
Safety hazards: The safety of lithium batteries is relatively poor, and it may occur.
Slow charging speed: The charging speed of lithium batteries is relatively slow, usually taking about 1 hour.
In general, graphene batteries and lithium batteries have their own advantages and disadvantages, and which battery to choose depends on the specific application scenario and needs. For example, if long endurance and fast charging are required, a graphene battery may be a better choice; If higher energy density and lower ** are required, then lithium batteries may be a better choice.
