Lithium-ion batteries generally lose their performance over time, however there are a number of steps we can take to make them last longer which we explore in this video and the science behind why each one works.
00:00 Introduction
00:23 Reduce time at high state-of-charge
02:15 Don't let the battery get too hot
03:08 Use slow charging
03:51 Avoid overcharging
05:02 Avoid overdischarge
05:42 Key points for a long lifetime battery
tl;dr
1. Reduce time at high state-of-charge (~85% is about right)
2. Don't let the battery get too hot (~20 °C is ideal)
3. Use slow charging (Fast charging can cause dendrites)
4. Don't overcharge (Battery will expand and bulge)
5. Don't overdischarge (Current collector will dissolve+cause short circuits)
