No. Eleven slave states did secede and join the Confederacy.
In three other slave states there was some effort at secession, by part of the people at least, but they are not considered to have left the Union. The men from these states divided, some fighting for the north, some for the south. These were Maryland, Kentucy and Missouri. The slave state of Delaware, seeing how Maryland was punished and prevented from seceding, did not try to secede.
And there were still some slaves in some northern states, but not a great many. For instance, there were still a small number of slaves in New Jersey in 1865, when the war ended.
The eleven "Southern" states that seceded from the Union were all "slave" states. The slave holding states of Missouri, Kentucky, Maryland and Delaware were termed to be "border" states and geographically, none of them can be describes as "Southern" states, especially Delaware.
The Missouri Compromise, 1820, where Missouri was admitted to the Union as slave-holding state, but all other states to come of the Louisiana Purchase should be non-slavery states.
The slave holding states at the time of the US Civil War were: South Carolina, Mississippi, Florida, Alabama, Georgia, Louisiana, Texas, Virginia, Arkansas, Tennessee and North Carolina. Northern states where slavery was still legal were: Delaware, Maryland, Kentucky, and Missouri. They were the Border States that remained in the Union.
West Virginia broke apart from the slave state Virginia and joined the Union, but for the most part all slave states were Confederate.
The Confederate leaders wanted as many states as possible to join them. Whether non-slave states could join was moot, since all of the non-slave states were in favor of preserving the Union.
The Fugitive Slave Act of 1850 required all states to help slave owners recapture their runaway slaves, even if those states did not practice slavery. This law allowed slave owners to pursue escaped slaves into free states and required citizens to assist in their capture.

All the non-slave states, plus four slave-states that did not vote Confederate - Kentucky, Missouri, Maryland, Delaware.
If its the end of slavery then all of the states were free
No. The Dred Scott decision basically said all the states of the USA were slave states and a slave in a "free" state was still a slave. The Dred Scott decision helped to lead to the Civil War.
When all of the Confederate states became solidified as one collective rebellion, there were 15 slave states in the US. Of the fifteen, four slave states did not secede. Nineteen were free states. Thus as the war was fully underway, there were eleven Confederate states and 23 Union states. The slave states that did not secede were called "Border States". These were Delaware, Maryland, Kentucky and Missouri. Only the latter three states played a roles in the war.
Yes, colonial Delaware was a slave-holding colony. Slavery was legal and practiced in Delaware from the early colonial period until the end of the Civil War. The economy of the colony relied on slave labor for industries such as agriculture and shipbuilding.
