Summary Reader Response Draft 3
The article “Everything You Need To Know About Tesla’s New 4680 Battery Cell”, written by Field (2020), talks about how the new battery is a game changer. The new improvements and features that Tesla has made to its battery has led to the Tesla’s 4680 tabless battery. There are many kinds of battery out there and the 4680 is a specific type of lithium-ion (Li-I) made by Tesla. Li-I battery is a rechargeable battery being widely used in many areas like electronics, electric vehicles and energy storage systems. However, the 4680 is made specifically for the use in Tesla’s electric vehicles. The 4680 is a total redesign of the battery compared to its previous model 2170. The major improvements made to the 4680 were, more efficient battery performance and improved thermal dissipation than the previous models. Another reason is because the process of manufacturing the battery has become less complex.
The second improvement for the 4680 is the improved manufacturing
process and reduced cost. According to the webpage (Tesla 4680 battery….,
2022), the main reason for this is because of the new design and science of the
battery. During the manufacturing of the 2170, the production needs to be
continuously started and stopped because it has a tab. However, when
manufacturing 4680, it can reach a very high speed without the need to be
stopped as the 4680 is tabless and this allows the production process to be
fast and less likely for there to be any defects with the battery (Tesla 4680
battery…., 2022). Since the manufacturing process is fast it can produce more
batteries in less time. Another reason is because of their new dry coating
process. Kazarian (2023), mentions that the old method of coating the electrode
compared to Tesla's new method of dry coating is more efficient and faster. The
old method involves a wet chemical slurry and drying it before the final
assembly of the battery. However, since the new method involves dry coating,
this eliminates the need for the drying process. Therefore, the new dry coating
process leads to reduced cost, energy usage and manpower.
Third improvement to the 4680 is its thermal dissipation.
According to Field (2020), Tesla was able to manage the heat dissipations
effectively because of its new tabless design. Bower (2020) mentions that the
tabless design allows for decreased resistance inside the battery. This is
possible because at each point of the 4680, there are cooling pads made of
electrons which allow for heat to be pulled out from the centre of the battery
to either ends of the battery. As a result, it helps in the thermal dissipation
of the battery. Field (2020) also mentions that, although the 4680 is bigger it
has reached similar heat dissipation compared to smaller batteries.
With every new technology out there, there will always be some
limitations and disadvantages to it. Unfortunately, this is the same for the
4680. The drawback of the 4680 is that it is new. According to the webpage
(Main Features and…., 2023), 4680 is still in its early stages and needs to be
used more as it does not have enough reliability and needs to be tested more.
Since it's a new technology it is even harder to come up with a production line
as the designs are still all too new and it requires new equipment. As a
result, Tesla can have trouble producing a large amount of 4680 batteries.
In conclusion, the 4680 is a superior battery compared to its
predecessors like the 2170 battery. It might be the future of the next gen electric
vehicle cars. Even with so many promises this technology is still new and needs
time to mature. Only time will tell how great Tesla’s 4680 can be.
