Graphene lithium-ion batteries are a type of rechargeable battery.
Lithium batteries generally use materials containing lithium as electrodes, and mainly work by the movement of lithium ions between the positive and negative electrodes.
During charging, lithium-ion batteries transfer electrolyte from the positive electrode to the negative electrode, which is then in a lithium-rich state. Discharging is different.
After adding graphene material to lithium-ion batteries, charging, discharging, and conductivity are more than 10 times faster than the original batteries. They can be fast-charged to 110-240V household electricity (fully charged in 15-25 minutes). This reduces the causes of heat generation and aging-related fires, and increases the battery's lifespan by several times.
The advantages of graphene lithium-ion batteries can be summarized as follows:
High operating voltage (three times that of nickel-cadmium and nickel-metal hydride batteries);
It has a high energy density (up to 165Wh per kilogram, three times that of a nickel-hydrogen battery);
Small in size (30% smaller than nickel-metal hydride batteries);
Lightweight (50% lighter than traditional batteries);
Long cycle life (approximately 2500-3000 cycles);
Low self-discharge rate (only 3% self-discharge per month);
No memory effect (the depth of charge and discharge does not affect the battery's capacity and lifespan);
Pollution-free (the battery materials do not contain toxic substances).
