As Xoa posted in another branch, it’s not true that batteries aren’t much better in the last 15 years. Lithium Ion is not a single type of battery but a category of batteries with many types, each with their own benefits and challenges. Numerous changes have been made to the anode and cathodes to improve stability, power capacity, recharge cycles and cost. Recent efforts have focuses on reducing or removing cobalt. Capacity has grown about 5% per year and general stability has improved. I remember reading articles like this years ago where they talked about using LFP cathodes to improve the stability of batteries. Today LFP batteries are used in some Teslas and probably other vehicles. https://arstechnica.com/science/2021/05/eternally-five-years-away-no-batteries-are-improving-under-your-nose/ https://arstechnica.com/science/2021/05/eternally-five-years...
