Tesla has unveiled its new battery cell, now known as the 4680, at its Battery Day event.

Tesla CEO Elon Musk and Vice President of Technology Drew Baglino unveiled the new 4680 battery cell at their Fremont factory presentation in California. The cell is the automaker’s big breakthrough in the company’s quest to create a more affordable electric car and battery technology.

The two Tesla executives detailed the company’s new cell, which aims to not only decrease production costs, but also increase energy density, power, and range for its electric vehicles. The new tabless battery design will increase manufacturing efficiency, leading to decreased cost per kilowatt-hour.

The new cell is bigger, offers six times the power of Tesla’s previous cells, and five times the energy capacity.

This is just the beginning. Tesla’s cell efficiency could reduce the cost per kWh by 14%, but the ultimate goal is to reduce it by 50%. This goal can be accomplished by increasing the manufacturing of cells through company factories, increasing the efficiency of anode and cathode materials, and cell vehicle integration.
