Vehicle battery positive plate lead paste formula

Abstract

The invention provides a vehicle battery positive plate lead paste formula, and relates to a storage battery for vehicle. At present, the lead acid battery faces a dilemma of low specific energy and short life in the technology requirement. The vehicle battery positive plate lead paste formula is characterized in that, the positive plate lead paste formula contains: lead powder 100 kg, short fiber 0.03-0.10 kg, tetracid base type lead sulphate particle 500-1000 g, active carbon 1300-1700 g, carboxymethylcellulose sodium 100-200 g, conductive graphite 200-300 g, polyacrylamide 100-150 g, gas phase silica powder 100-200 g, deionized water 10000-13000g, and 1.30-1.40 g/cm<3> (25 DEG C) sulfuric acid 8000-9000 ml. The invention has the beneficial effects of high specific energy, strong heavy current charge and discharge capability, high low temperature capacity and lasting cycle.

Description

technical field [0001] The invention relates to a storage battery for a vehicle, in particular to a formulation of a lead paste for a positive plate of a vehicle battery. Background technique [0002] With the advent of the new energy era, the discovery of electric vehicles (including hybrid and pure electric power) is changing with each passing day. At present, the power battery of electric vehicles has become the focus of attention in the electric vehicle industry. At present, the safety and cost performance of lithium batteries have not been obtained. Under the condition of effectively solving and other chemical power sources that cannot be effectively used in civilian use, lead-acid batteries have become the power source with the largest consumption and the strongest practicability. At the same time, the application mode of lead-acid batteries has changed from the conventional standby and low current and low power application mode to the high current and high power appl...

[0002] With the advent of the new energy era, the discovery of electric vehicles (including hybrid and pure electric power) is changing with each passing day. At present, the power battery of electric vehicles has become the focus of attention in the electric vehicle industry. At present, the safety and cost performance of lithium batteries have not been obtained. Under the condition of effectively solving and other chemical power sources that cannot be effectively used in civilian use, lead-acid batteries have become the most used and most practical power source

At the same time, the application mode of lead-acid batteries has changed from the conventional standby and low current and low power application mode to the high current and high power application mode, which also faces the dilemma of low specific energy and short life in terms of technical requirements

At present, the common methods to improve the low specific energy and short life of lead-acid batteries in China are: 1. Thinning the electrode and increasing the specific surface area of ​​the electrode, but the production control quality cost is high and the efficiency is low; 2. Add soluble additives to the electrolyte to improve The specific surface of the battery in the early stage, but only increases the capacity in the early stage, and cannot continue to maintain the battery capacity; 3. Increase the concentration of the electrolyte, but accelerate the sulfation; 4. Add conductive substances to increase the depth of discharge, but the cost is too high
