Shows up fine for me. You may try resetting your phone:
Resetting Your Device: Hold the home button + the lock button for about 10-12 seconds until the Apple logo appears. You will not lose any data or current settings.

if you have 4 or more icons on the right(ie alarm, location service,rotation lock, bluetooth etc) the battery percentage will only appears after you unlock. If you want the battery percentage to appear in your lock screen, try to limit the icons on the right to 3 only(ie turning off rotation lock,bluetooth or alarm etc).
