Abstract: A secondary battery, a battery module, a battery pack, and an electric apparatus are described. The secondary battery includes a positive electrode plate and a non-aqueous electrolyte. The positive electrode plate includes a positive electrode active material. The positive electrode active material has a chemical formula of LiaAxMn1?yByP1?zCzO4?nDn, where A includes at least one of Zn, Al, Na, K, Mg, Nb, Mo, and W, B includes at least one of Ti, V, Zr, Fe, Ni, Mg, Co, Ga, Sn, Sb, Nb, and Ge, C includes at least one of B (boron), S, Si, and N, and D includes at least one of S, F, Cl, and Br. The non-aqueous electrolyte includes an organic solvent. The organic solvent includes a first solvent. The first solvent includes one or more of compounds represented by formula 1. Rate performance and cycling performance of the secondary battery are improved.
