  In this letter, based on the exponential scalar auxiliary variable
technology, we propose and study a new class of explicit energy-preserving
splitting methods for solving the charged-particle dynamics. The
energy-preserving property of these methods is rigorously analysed. We also
provide the error estimates for the new methods. Numerical computations are
presented, which confirm the effectiveness and superiority of these novel
methods in comparison with the standard scalar auxiliary variable approach.
