According to foreign media, Panasonic said it will increase the energy density of the 2170 cylindrical battery provided to Tesla by 20% in the next five years, and plans to deliver cobalt-free batteries between 2022 and 2023.
Although Panasonic did not specify whether to increase the weight density or bulk density (or both), the increase in energy density will be completed in several steps. Initially starting in September 2020, Panasonic will transform the Tesla Gigafactory in Nevada, using new production technology to increase the energy density of the currently mass-produced 2170 batteries by approximately 5%.
