4680 battery is a newer, larger type of lithium-ion battery that is currently being developed by Tesla for use in its electric vehicles. Here are some differences between the 4680 and the more commonly used 18650 battery:
Size and capacity: The 4680 battery is larger than the 18650 battery, which allows for a higher capacity. Tesla claims that the 4680 battery can provide up to five times more energy and six times more power than the 18650 battery.
C-rate: Like the 32650 battery, the 4680 battery is capable of handling higher discharge rates than the 18650 battery. This makes it more suitable for applications that require high power output.
Manufacturing efficiency: Tesla has designed the 4680 battery to be more efficient to manufacture than the 18650 battery. The company claims that the new battery design will reduce manufacturing costs while also improving performance.
Availability: As of now, the 4680 battery is not yet widely available, while the 18650 battery is commonly used in many consumer electronic devices and is readily available.
The choice between the 4680 and 18650 batteries depends on the specific requirements of the application. The 4680 battery may be more suitable for electric vehicles or other high-power applications, while the 18650 battery may be more appropriate for smaller devices that require a smaller size and lower capacity.
