2 Non-breaking space before SI units

I am currently designing a circuit similar to a cattle prod that is intended to be attached to a drone. The cattle prod is powered by a lithium-ion battery, charging up a capacitor and then quickly discharging through a material. It will be delivering approximately 1J1 J of energy with a 10kV10 kV voltage, at about 7kHz7 kHz. I am trying to make the system more efficient.

I know next to nothing about power electronics or batteries (I am studying computer science), and was wondering if it is possible to use any residual current from the discharge to cycle back through and recharge the battery without any mechanical components? If not, can you please explain why? I am currently looking at the MAX8900 IC, and if it is possible I would like to know what I would have to do to process the current so it could be the input to such an IC.

I am currently designing a circuit similar to a cattle prod that is intended to be attached to a drone. The cattle prod is powered by a lithium-ion battery, charging up a capacitor and then quickly discharging through a material. It will be delivering approximately 1J of energy with a 10kV voltage, at about 7kHz. I am trying to make the system more efficient.
