Musk shared tesla s long term goal of sustainable energy storage at battery day last week including a plan to power energy hungry vehicles such as its electric semi and cybertruck with high nickel batteries in a wider larger form factor.
The new cells are far cheaper and can store far more power per unit of volume.
Interestingly enough elon musk noted that tesla is only producing cells that feature high energy nickel cathodes for now.
During battery day tesla s slide outlining its cathode strategy listed.
The great potential of these anode free lithium metal cells in pouch format.
All told tesla s new 4680 battery cell represents a paradigm shift in automotive energy storage.
Proprietary anode and electrolyte coupled with a high energy cathode produced in house sion power has developed a patented protected lithium anode pla a key component that enables licerion batteries to store energy at levels unachievable by other battery technologies.
The nominal voltage of normal voltage cells is at 3 6 3 7v while the nominal voltage of high voltage cells is at 3 8v or 3 85v.
High voltage cells lithium ion polymer lipo battery cells with normal voltages are fully charged at 4 2v while high voltage cells are at 4 35v.
Tesla has been putting prototypes of its energy dense high nickel 4680 cells into vehicles for some months elon musk said on sunday.
Incorporating thin chemically stable ceramic barriers the licerion pla reduces parasitic reactions minimizing weight.
These should be suitable not only for cars but also for electric aircraft and drones.
This is another significant technical upgrade of bak after the energy density of the 2 75ah power battery cell 18650 which reached 240g kg.
