Improved accumulator partition

Abstract

This invention discloses an improved storage battery baffle in the following mass percentage for each component: medium alkali cotton: 45-65%, high alkali cotton: 35-55%, residual material: 0-5%, short fiber: 0-1%, nm SiO2: 2-6% and carboxymethylcellulose sodium: 0.01-0.5%, which increases the ability for absorbing electrolyte by adding some nm SiO2 and CMC.

Description

【Technical field】 [0001] The present invention relates to batteries, and more particularly to battery separators. 【Background technique】 [0002] The active material of the positive electrode of the lead-acid battery is lead dioxide, the active material of the negative electrode is lead sponge, and the electrolyte is a dilute sulfuric acid solution. +PbO 2 (Positive pole)+2H 2 SO 4 ====2PbSO 4 +2H 2 O (discharge reaction) Its charging chemical reaction is that lead sulfate and water are converted into lead dioxide, sponge lead and dilute sulfuric acid. 2PbSO 4 +2H 2 O====Pb (negative electrode)+PbO 2 (Positive pole)+2H 2 SO 4 (Charging reaction) The rated voltage of a single lead-acid battery is 2.0V. Generally, it is connected in series to 6V and 12V for the starting and lighting of automobiles and motorcycles. The single battery is generally connected in series to 48V, 96V, 110 or 220V for different occasions. The positive and negative plates in the battery use ...

Problems solved by technology

[0011] This type of separator has a low ability to hold the electrolyte. If the charging rate is too large, the amount of electrolyte will be lost prematurely, causing the electrolyte to dry up and cause thermal runaway, resulting in a shortened cycle life.
