Rare earth new power supply and its preparation method

Abstract

The invention relates to a new power supply, in particular to a rare earth new power supply and a preparation method thereof. Including the battery case, the inside of the battery case contains a battery cell, and a spring plate is provided between adjacent cells. The battery cell includes a positive and negative electrode assembly. The assembly is composed of alternately stacked positive and negative pole pieces packaged in diaphragm bags, and both sides of the positive and negative components are negative pole pieces; an air chamber is set on the battery case, and an air chamber is set between the air chamber and the battery case. With polyurethane cork. The combination of positive and negative pole pieces in the present invention, the elastic plate maintains the dynamic tightness of the pole piece, the air chamber improves the charge and discharge efficiency, and the multiple conductive strips increase the electron transfer speed, realizing the high current charge and discharge capacity of the battery, which can meet the requirements of 500A and above. Long-term, high-frequency charging and discharging with regular current; also solved the historical technical problem of slow heat dissipation. The invention also provides a preparation method thereof, which has a simple process and is environmentally friendly.

Description

technical field

[0001] The invention relates to a new power supply, in particular to a rare earth new power supply and a preparation method thereof. Background technique

[0002] Since the beginning of the 21st century, the field of pure electric large vehicles such as light rail and buses has developed rapidly, and the promotion and application of major cities are also changing with each passing day. They all need power sources that can be input and output for a long time and with high current characteristics, and power batteries are used as a DC The energy supply body has the characteristics of stable voltage, safety and reliability, and has great practical significance.

[0003] For a long time, one of the main bases for the evaluation of power batteries is high power, that is, the higher the power charging and discharging, the stronger the power. The body 1A and the single 100Ah secondary battery are both power batteries. Assume that the former can be charged and discha...
