    en.wikipedia.org/wiki/Battery_regenerator

    Conventional battery chargers use a one-, two-, or three-stage process to recharge the battery, with a switched-mode power supply including more stages in order to fill the battery more rapidly and completely. Common to almost all chargers, including non-switched models, is the middle stage, normally known as "absorption".

    en.wikipedia.org/wiki/Nickel–iron_battery

    Edison's batteries had a significantly higher energy density than the lead–acid batteries in use at the time, and could be charged in half the time; however, they performed poorly at low temperatures, and were more expensive. Jungner's work was largely unknown in the US until the 1940s, when nickel–cadmium batteries went into production there.

    The best NMC batteries exhibit specific energy values of over 300 Wh/kg. Notably, the specific energy of Panasonic’s “2170” NCA batteries used in Tesla’s 2020 Model 3 mid-size sedan is around 260 Wh/kg, which is 70% of its "pure chemicals" value. LFP batteries also exhibit a lower operating voltage than other lithium-ion battery types.
