All-solid-state hybrid power energy storage battery cell

Abstract

The invention discloses an all-solid-state hybrid power energy storage battery cell. The all-solid-state hybrid power energy storage battery cell comprises a soft package body, wherein at least one all-solid-state battery unit and at least one all-solid-state capacitor unit which are compounded together are arranged in the soft package body. According to the all-solid-state hybrid power energy storage cell disclosed by the invention, the all-solid-state battery unit and the all-solid-state capacitor unit are compounded together, so the volume and the weight can be reduced, and the energy density is improved; the all-solid-state battery units, the all-solid-state capacitor units and the all-solid-state battery units and the all-solid-state capacitor units can be randomly combined to outputelectric energy to the outside; the output electric energy proportion of the all-solid-state battery unit and the all-solid-state capacitor unit can be controlled according to different application scenes, so the all-solid-state battery unit always operates at the optimal multiplying power, and a purpose of long-distance and long-service-life recycling is achieved.

Description

technical field [0001] The invention belongs to the technical field of energy storage equipment, in particular to an all-solid-state composite power storage cell. Background technique [0002] Solid state batteries are a type of battery technology. Unlike lithium-ion batteries and lithium-ion polymer batteries that are commonly used today, a solid-state battery is a battery that uses solid electrodes and solid electrolytes. The traditional liquid lithium battery is also vividly called "rocking chair battery" by scientists. The two ends of the rocking chair are the positive and negative poles of the battery, and the electrolyte (liquid) is in the middle. Lithium ions are like excellent athletes running back and forth at both ends of the rocking chair. During the movement of lithium ions from the first capacitor electrode to the second capacitor electrode and then to the first capacitor electrode, the charging and discharging process of the battery is completed. The principl...
