| description | The invention provides a lithium battery and a power vehicle. According to the lithium battery, a lithium transition metal oxide and a LiFe1-aMnaPO4 material are mixed to be used as a positive electrode active material, and a relation is established between the mass ratio of the LiFe1-aMnaPO4 material and the content of vinylene carbonate in a battery electrolyte, the discharge capacity and direct-current internal resistance of the battery discharged at the temperature of 25 DEG C at 0.33 C, the content of Fe dissolved into a negative electrode material after high-temperature circulation and the like; and certain conditions are met, so that the battery can be ensured to have good 0 DEG C low-temperature rate performance and high-temperature cycle performance at the same time.
本申请提供了一种锂电池和动力车辆。该锂电池将锂过渡金属氧化物与LiFe1-aMnaPO4材料混用作正极活性材料，并将LiFe1-aMnaPO4材料的质量占比与电池电解液中碳酸亚乙烯酯的含量、电池在25℃下以0.33C放电的放电容量及直流内阻、高温循环后溶出到负极材料中的Fe含量等建立联系，并使它们满足一定的条件，以保证电池能兼顾良好的0℃低温倍率性能和高温循环性能。 |
