Embodiment Construction

[0011] Further illustrate the present invention and its beneficial effect through embodiment below.

[0012] see figure 1 , the battery in the embodiment is composed of six cells 3, in each cell, the pole plate 1 is parallel to the bottom surface of the casing, that is, parallel to the horizontal ground 4 during use, and the bus bar 2 connects the positive and negative plates to the Together. The production and comparison test of the battery are as follows:

[0013] Example one, add 0.5% strontium titanate in positive lead paste, and use negative ion water to carry out blending, the composition and weight percent of positive lead paste are: red lead 12%, sulfuric acid (1.4g / cm 3 ) 6.7%, short fiber (4d~6d) 0.1%, negative ion water 10%, strontium titanate 0.5%, and the rest is lead powder. The high temperature resistant PPO shell material is used, the positive and negative plates are parallel to the bottom surface of the shell, and the electrode group adopts the arrangement ...

Abstract

The invention provides a high-temperature-resistant medium-density battery, in which strontium titanate is added to the lead paste of the positive plate, and the pure water used in the preparation of the lead paste is negative ion water. The battery plate is placed parallel to the bottom surface of the case, that is, placed parallel to the ground, and the battery case is made of high-temperature-resistant PPO material. The battery of the invention is suitable for use in a high-temperature environment above 45° C., and its high-temperature float charge and high-temperature cycle performances are significantly improved.

Description

technical field [0001] The invention relates to a lead-acid storage battery, specifically a novel high-temperature-resistant medium-density battery. Background technique [0002] At present, valve-regulated sealed lead-acid battery technology has achieved great development and has been widely used in the communication industry, playing an important role in the development of the communication industry. With the continuous improvement of urban concentration, the battery room with a large area has been gradually eliminated, and the wireless integrated distributed base station technology of micro-cells has emerged, and the ambient temperature of the battery has also risen from the original 25°C to 45°C. The life of traditional medium-sized sealed batteries will decrease by 75% in high-temperature environments; at present, medium-density batteries cannot meet the requirements of high-temperature application scenarios, so it is urgent to develop a new type of high-temperature-res...
