Problems solved by technology

[0002] The performance of the lead-acid battery mainly depends on the performance of the positive electrode, especially the tubular fixed lead-acid battery, because the plate is thicker, and a layer of polyester pipe is installed outside the skeleton, which has a certain resistance, and has existed for a long time. Polarization is difficult and the utilization rate of active material (ie, lead paste) is low, which seriously affects the overall performance of the battery, resulting in low weight to energy and short cycle life.
In response to this situation, many manufacturers adopt low-current and long-term formation processes. Although the formation of positive plates has been improved to a certain extent, this method leads to too long formation time and wastes a lot of electric energy, resulting in energy waste. , and the growth of the production cycle leads to low production efficiency and no economy at all
There are also some manufacturers who add a single additive to the positive active material. Although the formation of the tubular positive plate has been improved, the overall effect is not great and the effect is not ideal.

Abstract

The invention relates to a tubular fixed lead-acid storage-battery anode active substance for energy storage, comprising lead powder, read led, nano-graphite, bitter salt, charcoal and silicon dioxide. The read led is capable of improving the transforming efficiency of the anode active substance and reducing the duration of formation; the sound conducting performance of the nano-graphite can improve the conducting capability of the active substance and facilitate charge and discharge of the storage battery; the bitter salt, charcoal and silicon dioxide can effectively improve the porosity of the active substance, thus building the network structure of the active substance to facilitate the electrolyte to melt into the active substance efficiently, thereby, the high-current discharge capability and the utilization ratio of the active substance are improved; besides, the invention is also environment friendly.

technical field [0001] The invention relates to the field of lead-acid batteries, in particular to a positive electrode active material of tubular fixed lead-acid batteries for energy storage. Background technique [0002] The performance of the lead-acid battery mainly depends on the performance of the positive electrode, especially the tubular fixed lead-acid battery, because the plate is thicker, and a layer of polyester pipe is installed outside the skeleton, which has a certain resistance, and has existed for a long time. This has seriously affected the overall performance of the battery, resulting in low weight-to-energy and short cycle life. In response to this situation, many manufacturers adopt low-current and long-term formation processes. Although the formation of positive plates has been improved to a certain extent, this method leads to too long formation time and wastes a lot of electric energy, resulting in energy waste. , and the growth of the production cyc...
