You managed to create lithium batteries lasting for 100 years (meaning an iPhone user can scroll for a long time until the individual dies of old age without stressing if the phone will run out of battery). To put it into perspective: Nuclear Submarines can go on without refuelling for at least 50 years, so if you double that lifespan on a lithium battery: how would it shape modern electronics? What would it be like having a battery that can last an entire century?
That would mean iPhone & Android users don’t have to recharge every 10 hours or so (becomes every 876000 hours) meaning let’s say you bought an iPhone whilst in school it’s a full bar, by the time you are at old age living your golden years (it hits 5%) and throughout your entire life you forgotten that phones need to be recharged due to having a device that can last basically forever due to the battery being that powerful & having a long lifespan.
…. Is exactly what we need. People bitch and moan about how difficult it is to replace phone batteries, but this would make it unnecessary. More importantly, all those people who replace their phones every 2-3 years as the battery stops lasting a full day, would no longer have that excuse. If we had increased longevity, there’d be less electronic waste as people keep their devices longer
Or think about things like grid storage - a lot of the high cost is how long they last, so increased longevity is critical for that investment to pay off.
Or v2g. People are finally coming around to trust that EV batteries will last longer than they will own an EV, ut most of us still don’t trust vehicle to grid connections to not unnecessarily age our vehicle battery
But less electronics waste is less profit. If everyone who bought a 2 year phone bought them every 4 years instead, that’s a 50% drop in sales.
