Tesla Battery 4680 vs 2170

The world of electric vehicles (EVs) is constantly evolving, and battery technology is at the forefront of this progress. Tesla, a leading innovator in the EV space, has introduced a new battery format – the 4680 lithium battery – promising significant advancements over its predecessor, the 2170 battery. But how exactly do these two technologies compare? Let’s delve into the key differences between 2170 vs 4680 batteries.

Size and Energy Density:

The most striking difference lies in the physical dimensions. The 4680 boasts a larger format (46mm diameter, 80mm height) compared to the 2170 (21mm diameter, 70mm height). This translates to a larger cell volume and theoretically, the potential for higher energy density (the amount of energy stored per unit mass). However, current 4680 cell battery in production may not quite reach the energy density of some 2170 cells due to factors like thicker cell walls for structural purposes in Tesla’s “cell-to-chassis” design.

Performance and Longevity (4680 vs 2170 battery):

Tesla claims that the 4680 lithium ion battery offers up to a 16% increase in driving range and a 6 times faster charging rate compared to the 2170. While independent testing is still ongoing, these figures suggest a significant leap in performance. The question of 4680 vs 2170 longevity is yet to be definitively answered. Both battery types are expected to have long lifespans, but real-world data on the 4680’s longevity is still limited.

Cost Considerations (2170 vs 4680 cost):

One of Tesla’s primary goals with the 4680 is to achieve cost reduction through a simplified manufacturing process using fewer cells and potentially less complex battery pack designs. While the 4680 li ion battery itself might be more expensive to produce due to its size, the overall pack cost could be lower. However, it’s important to note that currently, 4680 batteries are not widely available for purchase (4695 battery for sale).

Who Invented the 4680 Battery?

While Tesla is heavily associated with the 4680 format, it’s important to clarify that they weren’t the first to develop the concept of a larger cylindrical lithium-ion cell. However, Tesla’s innovation lies in their adaptation of the format for mass production in their vehicles and the “cell-to-chassis” design that integrates the battery pack into the car’s structure.

Is the 4680 Battery Better Than the 2170?

The answer depends on your priorities. The 4680 offers the potential for greater range, faster charging, and potentially lower production costs in the future. However, current 4680 cells might not quite match the energy density of some 2170 cells, and long-term data on their longevity is limited.

The Future of Tesla Batteries:

The 4680 battery represents a significant step forward in battery technology for Tesla. As production ramps up and technology matures, we can expect to see further improvements in 4680 battery specification and overall performance. While the 2170 will likely remain in use for some time, the 4680 ushers in a new era for Tesla and potentially the broader EV industry.
