The 1st thing wrong is you have no specs for desired output, thus no way to verify your design.
2nd and more importantly, there is no purpose specified, as the 24V battery has far more Farads than all your Capacitors.
3rd L& C elements will resonate according to 2pi*f=1/√(LC) with ringing dampened on half cycles due to diode and R load.
4th. What is the diode? a laser? LED string? a strobe panel?
Whatever, what specs?
Always start any design with Specs for output, then process then inputs avail. This should also include any important requirements like cost, reliability, time and Environment specs for compatibility.
This requires skill and is the expected output of any Engineer.
