powershell.exe

When powershell.exe is started, it determines the required environment and loads the correct CLR (Common Language Runtime) and (managed) PowerShell host (Microsoft.PowerShell.ConsoleHost.dll) (See this link for more information).

Executing a PowerShell script in a cmd.exe batch file

The following example tries to demonstrate how it is possible to execute a PowerShell «script» in a cmd.exe batch file:

@powershell -command "" ^
                        ^
  $i = 1;               ^
                        ^
  while ($i -le 10) {   ^
    write-output $i;    ^
    $i++;               ^
  }                     ^
                        ^
""

A few notes:

End each line with a caret (^) which is the line continuation character in cmd.exe
Explicitly terminate each statement with a ; because the caret does not pass a new line
Start and end the script with a doubled quotation mark ("")

Note that it is also possible to execute a PowerShell script with the -f or --file command line option.
