Description

technical field

[0001] The invention relates to the technical field of aluminum electrolytic capacitors, in particular to an electrolyte, a method for preparing the electrolyte and an aluminum electrolytic capacitor. Background technique

[0002] In recent years, with the rapid development of new energy vehicles, solar photovoltaic power generation systems, AV servo amplifiers, automotive electronics, and aerospace and military industries, electronic components for complete machines have been placed with higher and higher requirements for use. Among them, the demand for high-stability and long-life aluminum electrolytic capacitors in related industries is increasing. However, most aluminum electrolytic capacitors with a temperature resistance of 105°C are currently on the market, which cannot fully meet the development needs. Therefore, the demand for aluminum electrolytic capacitors with higher stability and better temperature resistance in related industries has become in...
