Alternatively, relevant to universal thermodynamics, Hayward studied thermodynamics for dynamical black hole [16,17]. He in-troduced the notion of trapping horizon in 4D Einstein gravity for non-stationary spherically symmetric spacetimes and showed that Einstein’s equations are equivalent to the unified first law. Then,projecting the unified first law along any tangential direction (ξ)to the trapping horizon, one is able to derive the first law of ther-modynamics [18–20], i.e.,Clausius relation of the dynamical black hole, i.e.,Aψ, ξ =κ8πGdA, ξ, where energy flux ψis termed as energy supply vector.
