In the past two years, in the field of power batteries, the 4680 battery can be regarded as the most concerned one. According to the latest report, Panasonic Chief Financial Officer Hirokazu Umeda said on Wednesday that they are retrofitting some facilities and expects to start trial production of 4680 electric vehicle batteries at an undisclosed location in Japan at the beginning of the fiscal year starting in April.
After that, the company also intends to conduct further trial production in Wakayama Prefecture, near Panasonic’s Osaka headquarters, but the time and location of official mass production have not yet been determined.
Tesla has an extremely strong demand for the 4680, so when we can actually deliver the 4680, our plan is to give Tesla a priority, Umeda said. It is reported that Tesla officially announced the 4680 battery cell in September 2021, claiming that the energy of the single-cell has been increased by 5 times, the cruising range of the whole vehicle has increased by 16%, the power has been increased by 6 times compared with the battery with tabs, and the power output has been increased by 6 times. times.
This “revolutionary” battery has aroused heated discussions in the industry as soon as it was unveiled. It can not only increase the cruising range by 16% but also save 86% of the cost, which will make Tesla’s new car more affordable. Everyone has been looking forward to the launch of the 4680 battery model.
According to previous reports, the 4680 battery has a wider diameter and higher height than the previous 21700 battery. It consists of only 950 cells and has an energy density of about 300kWh/kg.
At the same time, the 4680 battery also uses laser electrodeless ear technology to remove the main heating components of the battery, reducing the internal resistance, and the thermal stability and controllability of the battery is higher.
