You can use to_datetime with the '%Y%m%d%H%M' format:

df['Date-time'] = pd.to_datetime(df['Date-time'], format='%Y%m%d%H%M')

output:

             Date-time
0  2022-05-22 00:00:00
1  2022-05-22 00:05:00
2  2022-05-22 00:10:00
3  2022-05-22 00:15:00
4  2022-05-22 00:20:00
5  2022-05-22 00:25:00
6  2022-05-22 00:30:00
7  2022-05-22 00:35:00
8  2022-05-22 00:40:00
9  2022-05-22 00:45:00
10 2022-05-22 00:50:00
11 2022-05-22 00:55:00

Use format as parameter of pd.to_datetime:

df['Date-time'] = pd.to_datetime(df['Date-time'], format='%Y%m%d%H%M')
print(df)

# Output
             Date-time
0  2022-05-22 00:00:00
1  2022-05-22 00:05:00
2  2022-05-22 00:10:00
3  2022-05-22 00:15:00
4  2022-05-22 00:20:00
5  2022-05-22 00:25:00
6  2022-05-22 00:30:00
7  2022-05-22 00:35:00
8  2022-05-22 00:40:00
9  2022-05-22 00:45:00
