We see that both Li+1 and B+1 have completely filled shells, the stable "inert gas" configuration. We would expect it to be difficult to remove one electron from these two ions and destroy this stable configuration. Further, we would expect removal of one electron from Li+1 to be more difficult than from B+1 because in the former case we are removing a 1s electron which is closer to the nucleus than the 2s electron in the case of B+1. On the other hand, if Be+1 loses one electron it will have a 1s2 electron configuration and achieve a stable "inert gas" configuration. This should make it much easier to remove one electron from Be+1 than from the other two ions.
