Problems solved by technology

Due to the high cost, scarcity of materials, and hidden dangers in safety, lithium-ion batteries, as a mass market consumer product, have many bottlenecks
Lead-acid battery users need to replace it after about one year of use. The service life is short. The main reason for battery failure is that the electrolyte is dry and the positive electrode active material is softened, which brings great technical obstacles to the market demand for new energy battery vehicles.

Embodiment 1

[0019] A deep-cycle storage battery is internally formed into lead paste, including positive electrode lead paste and negative electrode lead paste, wherein the components of the positive electrode lead paste are calculated by mass percentage: 0.15% carboxymethyl cellulose, 0.25% heterosexual graphite, 0.20% potassium sulfate, 0.35% stannous sulfate, 0.08% polyester staple fiber, 6.8% dilute sulfuric acid, 9% water, 83.17% lead powder; the components of negative lead paste are calculated by mass percentage: barium sulfate 0.50%, acetylene carbon black 0.20%, 0.25% lignin, 6% dilute sulfuric acid, 9.5% water, 83.55% lead powder.

[0020] The specific gravity of dilute sulfuric acid used in positive electrode paste and negative electrode paste in this embodiment is 1.400g / ml at 25°C. Before mixing the paste, the dilute sulfuric acid should be fully circulated and stirred to ensure that the paste acid meets the process requirements; The resistivity is not less than 1MΩ to prevent...

Abstract

The present invention discloses a deep circulation storage battery container formation diachylon, and is to solve the technical problem of short circulation life of conventional storage batteries. The diachylon of the present invention includes a positive diachylon and a negative diachylon. The positive diachylon includes the components by weight: 0.15-0.42% of carboxymethyl cellulose, 0.25-0.42% of anisotropy graphite, 0.15-0.25% of potassium sulfate, 0.30-0.42% of stannous sulfate, 0.07-0.10% of polyester staple fibers, 6.5-7.5% of dilute sulfuric acid, 9-10% of water, and 80.89-83.58% of a lead powder; and the negative diachylon includes the components by weight: 0.50-0.70% of barium sulfate, 0.20-0.45% of acetylene black, 0.15-0.25% of lignin, 6.00-6.50% of dilute sulfuric acid, 9-10% of water, and 82.10-84.15% of a lead powder.

Description

【Technical field】 [0001] The invention relates to an internalized lead paste for a power storage battery. 【Background technique】 [0002] At present, power-type lead-acid batteries are mainly used in the field of electric bicycles and electric road vehicles, and the battery cycle life is mostly about 300 times. Due to the shortcomings of high cost, scarce materials, and hidden dangers in safety, lithium-ion batteries, as a mass market consumer product, have many bottlenecks. Lead-acid batteries need to be replaced after about one year of use, and the service life is short. The main reason for battery failure is that the electrolyte dries up and the positive active material lead paste softens, which brings great technical obstacles to the market demand for new energy battery vehicles. In the market, batteries with long service life and many cycles are needed as the power source of electric vehicles. 【Content of invention】 [0003] The problem to be solved by the present i...
