Apple isn't going to be selecting for mass/energy density. That's a major concern for EVs, but for a phone, you would gladly take double the capacity for 3x the mass.
- magila 5y agoEV battery capacity hasn't exactly been skyrocketing either. When the Tesla Model S was introduced in 2012 the largest battery option was 85 kWh. For the 2015 model year it got a 90 kWh option and 100 kWh for 2016. Today 100 kWh remains the most you can get.
- zardo 5y agoHow has the mass changed? If we're talking about a fraction (density) it's pointless to talk about the numerator on its own.
- magila 5y agoI can't find any indication that the weight of Tesla batteries has changed significantly since the introduction of the 100 kWh pack. In any case weight savings on Tesla batteries seems to have come primarily from improved packaging rather than better chemistries.
