500% more EV range: Panasonic’s 4680 battery to skyrocket electric vehicle efficiency

Panasonic is set to begin mass production of 4680 battery that will increase energy density and boost EV range efficiency by 500%.

Panasonic maintains that the 4680 cylindrical automotive lithium-ion batteries offer substantial improvements over the conventional 2170 cells. The company claims that these new cells possess five times the energy capacity of the 2170 cell. This not only extends the driving range of EVs, but also reduces the number of cells required for the same battery pack capacity.

This results in a more efficient battery pack assembly process and ultimately lowers the cost of EVs, making them more affordable to a wider market. The manufacturing process of the 4680, with its larger capacity per cell, requires more advanced technology and expertise, according to the company.

4680 cells’ production to begin at Wakayama factory in Western Japan

Panasonic Energy claimed that it has leveraged its 30 years of know-how in the development of cylindrical lithium-ion battery technology to pioneer a mass production method for high-performance 4680 cells, setting a benchmark in the industry.

The company maintained that Wakayama factory in Western Japan will now act as the mother factory for the production of 4680 cells and will serve as a demonstration hub for new products and methods.

The factory will play a key role enhancing product quality and competitiveness, with processes newly trialed there set to be implemented globally in other factories. By March 2025, it is expected that roughly 400 staff will be involved in the development and production of next-generation batteries at the Wakayama factory, according to Panasonic .

4680 battery to significantly revolutionize EV industry

“I am excited that we are ready to start the mass production of the cutting-edge 4680 cell,” said Kazuo Tadanobu, president and executive officer, Panasonic Energy.

“This milestone is the result of years of expertise in cylindrical lithium-ion battery manufacturing. I’m confident it will significantly revolutionize the battery and EV industry. As we add the 4680 cell to our lineup, we’ll cater to a broader range of needs, further promoting the use of EVs and advancing our mission of fostering a sustainable society.”

With the goal of achieving environmentally friendly manufacturing, the Wakayama factory plans to utilize renewable energy sources like solar power and onshore wind power to the fullest extent, aiming for virtually zero CO2 emissions during its production processes, said Panasonic in a press release .

The company claimed that its eco-conscious approach has already been successfully implemented at the company’s Moriguchi base and Kaizuka factory in Osaka, resulting in the achievement of carbon neutrality across all nine of the company’s domestic bases as of September 2024. Panasonic Energy aims to extend this achievement to all 20 of its global bases by March 2029.
