I am not an expert on mining, but I do know my way on fossil fuel extraction. Getting oil from the earth and making it into fuel is not as easy as it sounds, and really the process is way more contaminant than extracting metals from the ground. To make it more clear I can try to explain it in parallel, in both you extract the resource from the ground, ...

Your friend is wrong and here's why. Lithium is mined once and can be reused in any number of vehicles. When the vehicle breaks, its lithium will replace newly mined lithium. If we need let's say 2 billion cars on the road with batteries, they need a certain fixed amount of lithium. If we need 2 billion oil-burning cars on the road, they will continuously ...

Recharging (rechargeable) lithium-ion batteries is — unfortunately — not a straight-forward process. Unless you cap current you will damage severely-discharged batteries during the initial charging phase. They react very poorly to being overcharged. Even small amounts of undervolting will translate to large amounts of capacity loss. Added to that, there ...

Energy losses in a cable — due to resistance — are proportional to the current squared (I²). Thus if you double the current (by putting your panels in parallel) then you'll quadruple your losses ( (2I)² = 4I² ). When panels are connected in series, the voltages add up but the current remains constant. Thus to minimise line losses, connect panels in series....

Reuse beats recycling. The active duty life span of an EV battery (cells and control electronics both) is hugely longer outside of an EV, so reclaiming lithium from them should be a last resort only at the point where no more economical uses for them exist. Thinking of the huge electric vehicle batteries as resources to recycle, once they no longer serve ...

People tell me they think I should get rid of all my old vehicles. I'm not willing to do so because each of them has a fully functional, rechargeable 12 volt system with around 48 amp hours each, which means that, fully charged, they will each deliver 1 amp for 48 hours, 2 amps for 24 hours, 8 amps for 6 hours and so on. Each can provide light, heat, shelter,...

In the recycling of lithium-ion batteries, cobalt is first in importance while lithium is second: "Rechargeable battery waste, particularly from lithium-ion batteries, will become an increasingly menacing environmental challenge in the future as the demand for these through their usage in electric vehicles and other gadgets increases dramatically," Ajayan ...
