The embodiment of the invention provides a lithium battery, a production process of a positive electrode, a negative electrode and an electrolyte, and a vehicle. The lithium battery comprises a positive electrode, a negative electrode and electrolyte; wherein at least one of the positive electrode and the electrolyte is a lithium-rich material; the electrolyte is a solid electrolyte with a phase change property; and the negative electrode is a lithium-free negative electrode. According to the embodiment of the invention, the battery capacity of the lithium battery is kept through the lithium-rich material under the condition that the safety of the lithium battery is ensured by adopting the lithium-free negative electrode; and based on the solid electrolyte with the phase change property, gaps existing in the solid electrolyte are reduced, so that the impedance of the lithium battery is reduced, and the cycle performance of the lithium battery is improved.
本发明实施例提供了一种锂电池、正负极和电解质的生产工艺以及一种车辆;锂电池包括正极、负极和电解质;其中,正极和所述电解质中,至少一个为富锂材料;所述电解质为具有相变性质的固态电解质;所述负极为无锂负极。通过本发明实施例,实现了在采用无锂负极来保证锂电池安全的情况下,通过富锂材料保持了锂电池的电池容量;且基于具有相变性质的固态电解质,减少了固态电解质中所存在的间隙,进而降低锂电池的阻抗,以及提高锂电池的循环性能。
