Battery prototype with 5x energy storage -Lithium - Ion Battery Equipment

Tesla has been driving innovation in the electric vehicle (EV) market and promises major changes and advancements in the battery of the future. Now, backed by the Japanese tech giant, the new battery will have five times the energy storage capacity and will help Tesla reduce production costs.(Lithium - Ion Battery Equipment)

In addition, Panasonic said the development of its latest project, the Tesla 4680, will be made explicitly for Tesla cars. This further strengthens the bond between the two companies. Kazuo Tadanobu, head of Panasonic's energy business, unveiled the battery prototype at a recent media roundtable, explaining why Panasonic developed the product, saying it was also "a strong desire from the other side."

No details have been released on when the 4680 cells will go into full production, but the company plans to start "trial production" early next year. Panasonic's development closely follows Tesla's own plans to develop the 4680 battery: a battery measuring 46mmx80mm.

energy solutions

Across the electric vehicle industry, automakers have been working to improve batteries by adding new ranges and charging speeds. When improving battery cells, EV makers may encounter other issues, such as an increase in battery size, resulting in a larger footprint and potential thermal management issues.

The new 4680 battery should supply more power, thus improving battery performance. Additionally, these cells will cost 50% less to produce compared to other models and will increase Panasonic's production by 100 times over the next decade.

However, while 4680 batteries offer some energy solutions, they are larger in size and raise questions about thermal management. Musk recently explained on Twitter in response to some questions: "Our new battery is 46mm in diameter and has a steel case, and even that will be a huge challenge to fight transmissibility."

Panasonic may adopt Tesla's workaround in production, which was unveiled at last year's "Battery Day" event, changing the form factor by placing cooling pipes above and below the battery to dissipate excess heat. When combined with an innovative label-free battery design, Tesla found a formula for optimal thermal management in its 4680 cells.

company relationship

Panasonic has been working with Tesla to find innovative and practical battery solutions, having previously built an improved 2170 lithium-ion battery for the Tesla Model 3 in 2017.

Kazuo Tadanobu, vice president of Panasonic, said the decision to move forward with production of the 4680 was "because of a strong desire from the other side, and we thought it would make our cooperation even closer".

The Japan-based electronics company has been a Tesla partner since it first launched the Model S in 2012. However, Tadanobu said the company has no plans to supply the lithium iron phosphate (LFP) electric vehicle batteries that Tesla is seeking.

As a result, Tesla began to diversify its battery maker portfolio and network, striking deals with South Korea's LG Energy Solutions and my country's CATL, and moving some production in-house.

Lithium iron phosphate (LFP) batteries are safer and cheaper than nickel-based batteries, but have lower energy density and require higher charging frequencies. In addition, lithium iron phosphate (LFP) batteries are more environmentally friendly because they require less rare earth material.

Tesla does plan to source lithium iron phosphate (LFP) batteries from my country's CATL and install them in some of its entry-level Model 3 and Model Y vehicles. By adding to its network of battery suppliers, Tesla also aims to make its entry-level cars more affordable, while hoping to spark innovation in the manufacture of fuel-powered lithium-ion batteries.

Tadanobu expressed little concern about Tesla's diversification of supply, saying the electric car maker is ready to buy everything Panasonic makes due to high demand for electric vehicles. For now, Panasonic will remain the only external manufacturer and supplier of 4680 batteries, although LG and CATL may follow.

Additionally, Panasonic's pre-production schedule appears to be in line with Tesla's next year's launch of its line of premium vehicles, including the highly anticipated Cybertruck. Tesla also recently confirmed that its 4680 trial production at its Fremont, Calif., plant will supply the first vehicles, but its partners, including Panasonic, are expected to help support the additional production.

"Tesla has very high expectations for shipments from our North American plant," Tadanobu said.

Panasonic's recent expansion saw its North American annual battery capacity additions: 38-39 GWh, up from 35 GWh in the year ending March 2021. So that's enough to meet the battery needs of more than 400,000 Tesla Model Ss.
