Re:EV Range Breakthrough as New Aluminum-Ion Battery Charges... by twobitshifter on Friday May 14, 2021 @09:53AM (#27154312)
The design of the iPhone and coin cell are similar. The iPhone battery is essentially a wrapped up coin cell. https://m.youtube.com/watch?v=RTjy2eFHzRc

In comparison a package battery like in an EV is made up of many individual cells to provide higher voltages. An iPhone can run on 3 or 4 volts, but a Tesla cannot.
