Supercapacitor battery

Abstract

The invention discloses a supercapacitor battery. The supercapacitor battery is mainly composed of electrodes, an electrolyte, a membrane, end plates, a lead and a packaging material. The main conductive material of the electrodes is silicon carbide. The electrode lead is directly connected with the battery end plates in a welding mode through a multi-strand sterepsinema with the diameter ranging from 1 mm to 4 mm, and the multi-strand sterepsinema is made of metallic titanium fibers or titanium alloy fibers. The NMP ultrahigh viscosity solution of methylamino butyric acid lithium, polysulfide lithium, lithium perchlorate and lithium phosphate serves as the electrolyte. A polyphenylene sulfide thin film serves as the membrane. The end plates are made of metallic titanium or titanium alloy. The packaging material is formed by welding an ultra-thick polyphenylene sulfide injection molding part and a thin film in a laser mode. One electrode, one end plate, the electrolyte, the membrane, the electrolyte, the other end plate and the other electrode are overlapped in sequence or wound into the 88-188 layers of the supercapacitor battery. The supercapacitor battery has the advantages of being high in temperature resistance, low in temperature resistance, corrosion resistant, short in charging time, large in number of circulation times and long in service life, and can be widely applied to places with the very hostile environmental conditions.

Description

technical field [0001] The invention relates to battery manufacturing, especially the technical field of power batteries. Background technique [0002] With the continuous development of the economy, it will inevitably lead to the depletion of oil resources, environmental pollution, and the aggravation of global warming. The development and comprehensive and efficient utilization of new energy, energy-saving technology and environmental technology has become a very necessary subject, and the development of electric vehicles is imperative. Supercapacitors have obvious advantages in the field of electric vehicles, which can meet the high power requirements of vehicles during acceleration, starting, and climbing to protect the main battery system. [0003] If used in conjunction with the power battery, the supercapacitor can act as a large current or energy buffer, reduce the damage to the power battery caused by high current charging and discharging, prolong the service life ...
