It’s not that simple… the voltages are all different, and each chemistry has different charge and discharge rates, so this just makes the end product insanely complicated and expensive.
We've already got programmable charging chips that can adapt to different chemistries, and they're already pretty cheap, and USB-C has proven that fancy voltage negotiation protocols can be done cheaply.
Users should be able to choose LiFePo4/LTO/Sodium for peace of mind and reliability if they don't need normal lipo levels of capacity.
