Making the right decision about which capacitor or battery to use can be difficult. They can also be used as a backup power source in case of an emergency or when the main power is not available. Capacitors are often

eli5:Why not use capacitors in electric vehicles instead of batteries

I''d could actually live with half of that but have 500kg capacitor-battery instead and recharging only takes seconds. Ah wait, thats another disadvantage: You need arm-thick cables to transfer the horrendous amount of current Reply reply More replies [deleted] • • Edited . To put this in context. Top end Lithium ion batteries have an energy density of around 300 Wh/k. Once built

Using capacitors instead of batteries

Using a large capacitor to store energy is generally not practical for most applications because capacitors have a much lower energy density than batteries. This means it would take a large capacitor to store the same energy as a smaller battery. However, capacitors do have some advantages over batteries in certain situations. They can charge
