High Energy Battery Cell

Tesla s battery research partner jeff dahn from dalhousie university provides an update on the new approach to cells with significantly higher energy density which was presented last year.

High energy battery cell.

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. 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. Incorporating thin chemically stable ceramic barriers the licerion pla reduces parasitic reactions minimizing weight. On may 16th bak battery was publicly listed and launched a new high energy battery cell of 18650 3 0ah with an energy density up to 250wh kg.

The great potential of these anode free lithium metal cells in pouch format. Ebl c size c cell 5000mah ni mh rechargeable batteries pack of 2 4 4. 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. Interestingly enough elon musk noted that tesla is only producing cells that feature high energy nickel cathodes for now.

This is another significant technical upgrade of bak after the energy density of the 2 75ah power battery cell 18650 which reached 240g kg. 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. Tesla has been putting prototypes of its energy dense high nickel 4680 cells into vehicles for some months elon musk said on sunday. The new cells are far cheaper and can store far more power per unit of volume.
