Electrolyte containing nano carbon tube

Abstract

This invention relates to an electrolyte containing nm carbon tubes, in which, carbon nm tubes of a preset weight percentage are added in a sulfuric solution, the weight percentage of which is 16-70, and that of the carbon nm tubes is 0.001-0.1 taking weight of the sulfuric solution as 100% here, in addition to that, SiO2 in a preset weight percentage can be added in the electrolyte as an additive material and content of nm carbon tube in the electrolyte can be adjusted to form an additive of electrolyte, which can be diluted to become an electrolyte filled in a lead-acid battery after the carbon nm tubes in it reach to a preset concentration.

Description

Technical field [0001] The present invention relates to an electrolyte for lead-acid batteries, in particular to an electrolyte containing carbon nanotubes and a sulfuric acid solution, which can be filled in a lead-acid battery as the electrolyte of the lead-acid battery. Background technique [0002] Batteries are mostly composed of cathode and anode electrodes, electrolytes and outer shells. Among them, the cathode is used to obtain higher performance, and the anode is used to increase the surface area for reaction. The electrolyte is generally also called electrolyte. [0003] After the electrolyte undergoes an oxidation-reduction reaction between the anode and cathode in the battery, electrons are transferred through the external circuit to generate current, and the internally charged ions are transferred between the anode and cathode through the electrolyte. Therefore, the use of a good electrolyte can make the anode and cathode Extreme discharge is more efficient. In the c...

In addition, although the patent mentioned in the abstract that it can provide the effect of charging and discharging with a large current, there is no data to prove that the activator does have this effect

Chinese Patent Publication No. CN1697236 discloses an electrolyte with nano-carbon used in valve-regulated sealed lead-acid batteries, which contains phosphoric acid and nano-carbon materials, wherein phosphoric acid accounts for 0.5-0.9 weight percent of the electrolyte, and nano-carbon materials account for electrolytic 1-7% of the weight percentage of the liquid; the electrolyte can increase the discharge capacity and service life of the battery, but the case did not mention carbon nanotubes

[0010] The composition materials and the concentration of the electrolyte of the traditional battery will affect the performance of the battery itself, and the traditional electrolyte is very easy to form a sulfuric acid concentration gradient, and the generation of the sulfuric acid concentration gradient will make the sulfuric acid in the electrolyte unevenly distributed, and will Reduce the speed of ion movement in the electrolyte, so it will directly affect the conductivity of the electrolyte itself, and even affect the conductivity of the battery
