I’m a big fan of the LiFePO4 chemistry. Super Cheap per kWh, abundant raw materials, extremely long cycle life (even without state of the art manufacturing), and usually a lot more stable and much less likely to start on fire. If you want to DIY a lithium battery pack, LiFePO4 is the least suicidal way to do it. I see LiFePO4 as enabling Africa to electrify quickly and cheaply. It’s feasible to hook up solar panels to an inverter/charger, a cheap and/or DIYed LiFePO4 battery pack, and combine it with a backup generator to have affordable (less than 15¢/kWh... potentially a LOT less) and (just as important) consistent power without needing access to the grid and that’s like 95% carbonfree.
