Embodiment 1

[0027] Example 1 Preparation of Electrolyte

[0028] Prepare a certain amount of electrolyte by conventional method, calculate according to weight percentage, add 0.5% phosphoric acid and 1% nano-carbon into the electrolyte, and control the density of the electrolyte between 1.24-1.28g / cm3 During the mixing time, the electrolyte solution with phosphoric acid and nano-carbon can be obtained by mixing evenly.

Embodiment 2

[0029] Example 2 Preparation of Electrolyte

[0030] Prepare a certain amount of electrolyte by conventional methods, and add 0.9% phosphoric acid and 7% nano-carbon to the electrolyte to control the density of the electrolyte between 1.24-1.28g / cm During the mixing time, the electrolyte solution with phosphoric acid and nano-carbon can be obtained by mixing evenly.

Embodiment 3

[0031] Example 3 Preparation of valve-regulated sealed lead-acid batteries for electric vehicles

[0032] Select Zhejiang Tianneng brand 6-DZM-12 storage battery. After testing, it is found that: when the current is 5A and the voltage is 12.3V, the discharge is terminated. Calculated by weight percentage, after adding about 1% of the original electrolyte to the electrolyte, the battery is charged and then discharged. When the current is 5A, the discharge time reaches 86 minutes and the voltage is 11.4V.

Abstract

The disclosed accumulator includes electrolyte, negative plate and positive plate. The electrolyte contains phosphoric acid and Nano carbon. According to weight percent, phosphoric acid and Nano carbon are as 0.5 - 0.9% and 1 - 7% of the electrolyte. The invention increases discharge capacity, prolongs service life, and makes worn-out accumulators possible to be recovered and reused again.

Description

technical field [0001] The invention relates to a lead-acid battery, in particular to a valve-controlled sealed lead-acid battery with nano-carbon in the electrolyte. Background technique [0002] Lead-acid battery is a device that converts electrical energy and chemical energy. It has been widely used and developed because of its high electromotive force, good charge and discharge reversibility, wide application range, simple production process, abundant raw materials and low price. . However, the current lead-acid battery has a limited service life, and the waste lead-acid battery also pollutes the environment. Contents of the invention [0003] The object of the present invention is to provide a valve-regulated sealed lead-acid storage battery with nano-carbon in the electrolyte with increased discharge capacity and increased service life. [0004] In order to achieve the above object, a valve-regulated sealed lead-acid battery with nano-carbon in the electrolyte of t...
