What would be the balanced chemical reaction if NiSO4.6H2O reacted with LiOH.H2O and (NH4)2S2O8 in the presence of H2O (as the solvent of the solution is H2O and heat? I am struggling to find a balanced chemical reaction.

It will only a precipitation of Ni(OH)2 take place.
Ammonium will release Ammonia.

Thank you for the response. Wouldn't the reaction look like:
NiSO4.6H2O + (NH4)2S2O8+2LiOH.H2O+H2O -> LiNiO2+LiHSO4+(NH4)2SO4+H2SO4?
If not, what would be the actual chemical reaction?

Can you read what I wrote?
Ni 2+ + 2 OH- => Ni(OH)2
And NH4+ + OH- => NH3 + H2O
I dont think S2O8 2- is strong enough to oxidise Ni in an aqueous solution as you wrote.
Maybe in a melted form it would be different
Ni 2+ + 4 OH- => NiO2- + 2 H2O + e-
S2O8 2- + 2 e- => 2 SO4 2-
