■ According to the a news report from Teslarati, Tesla started a hiring ramp for its 4680 pilot production line at its Fremont factory, which may hint that Tesla has solved its production calendaring challenges.
■ Each battery type offers different advantages and disadvantages and should be compatible with different technology solutions.
■ To move to the next big stage, issues such as duration, fast-charging efficiency and safety concerns still have to be addressed. We reiterate that battery technology remains the key for EV development. R&D capability has become one of the key indicators of the battery companies’ long-term growth visibility.
If Tesla’s 4680 cylindrical batteries can be put into mass production, we may see three groups of potential beneficiaries: 1) battery makers with R&D and production capacity for large cylindrical batteries, 2) battery materials suppliers that can produce silicon anode material and high-nickel cathode material, and 3) equipment suppliers, like manufacturers of cylindrical steel shells and automatic tab laser welding machines.
