specific Embodiment

[0017] Specific embodiment: when the supercapacitor battery is charged and discharged, the barium titanate supercapacitor battery uses double-layer capacitors and barium titanate as the electrolyte material, and the charging speed is fast, and it only takes tens of seconds to a few minutes to reach 95% of the rated charge Above, cycle charging and discharging can reach 500,000 times, the energy cycle efficiency of high current can reach more than 90%, and the operating environment temperature range is wide, from minus 40 degrees Celsius to minus 130 degrees Celsius. The buffer device can reduce the damage caused during transportation and reduce the cost. Barium titanate, as a lead-free and environmentally friendly material, also makes a great contribution to production efficiency.

Abstract

The invention belongs to the technical field of super capacitor battery, in particular to a barium titanate super capacitor battery. The barium titanate super capacitor battery includes a buffer device which is connected with a battery shell. A positive electrode slice is packaged on one side in the shell, and a porous electrode is arranged beside the positive electrode slice. The porous electrodeis filled with positive electrolyte, and an isolation membrane is arranged beside the electrolyte. Negative electrolyte is arranged on the other side of the isolation membrane, and the electrolyte iscombined with the porous electrode. A negative electrode slice is arranged beside the porous electrode. The electrode slices include a current collector, a bottom coating arranged on the surface of the current collector and a top coating arranged on the surface of the bottom coating. The bottom coating and the top coating include active substances, conductive agent and adhesive. The active substances of the coatings include a carbon material and a conductive polymer. The electrolyte is a lead-free material. Compared with the prior art, the barium titanate super capacitor battery has good transportation self-protection performance, electrochemical stability and environmental protection property.

Description

technical field [0001] The invention belongs to the technical field of supercapacitor batteries, in particular to a barium titanate supercapacitor battery. Background technique [0002] Supercapacitor is a high-efficiency, environmentally friendly and new type of energy storage element, which has many advantages of traditional capacitors and batteries, such as high energy density, long service life, high stability, high safety factor, environmental protection, fast charging and discharging, etc. It has broad application space and development prospects in consumer electronics, rail transit, aerospace, military, national defense and other fields, and has gradually become the focus of people's development research.
