Abstract

The invention discloses a super battery plate which comprises a positive plate and a negative plate; the raw materials of the positive plate consist of lead powder, carbon fibers, carbon materials, short fibers and sulfuric acid solution; the raw materials of the negative plate consist of lead powder, PTFE, barium sulphate, humic acid, lignin sodium sulplate, carbon fibers, carbon materials, short fibers and dilute sulfuric acid; the super battery prepared by the super battery plate has the advantages of high specific power and specific energy as well as long charge and discharge service life of a large pulse current. Moreover, the discharge of a low-temperature large current is batter than that of a common battery.

Description

technical field [0001] The invention relates to the field of electrochemical energy storage devices, in particular to a super battery plate. Background technique [0002] Most of the existing electric bicycles or motorcycles use valve-regulated sealed lead-acid batteries as the power source. Since valve-regulated sealed lead-acid batteries cannot realize high-current charging and discharging, the starting and uphill capabilities of electric bicycles or motorcycles are limited. [0003] Supercapacitor is a new type of energy storage device developed in recent years. It has the performance of fast charge and discharge, and its power density is dozens or even hundreds of times that of ordinary batteries. It has a long service life and can be recharged up to 100,000 times. , is hundreds or thousands of times that of ordinary batteries. Based on the special performance of supercapacitors, many electric vehicle manufacturers hope to apply supercapacitors to traditional electric b...
