Embodiment Construction

[0031] Below in conjunction with embodiment further illustrate method and effect of the present invention.

[0032] raw material:

[0033] Iron powder Fe 56 parts, sulfuric acid H 2 SO 4 98 parts, sodium carbonate Na 2 CO 3 106 parts, lithium hydroxide LiOH 24 parts, phosphoric acid H 3 PO 4 98 servings.

[0034] Production Method:

[0035] 1. Preparation of ferrous sulfate (FeSO 4 ):

[0036] Add excess iron powder (Fe) to 9mol / L dilute sulfuric acid (H 2 SO 4 ), ferrous sulfate (FeSO 4 ) solution for later use. Explanation: When iron (Fe) is excessive, sulfuric acid (H 2 SO 4 ) complete reaction, in the case of excess iron (Fe), ferrous (Fe 2+ ) ions will not be oxidized to ferric iron (Fe 3+ )ion.

[0037] 2. Preparation of ferrous carbonate (FeCO 3 ):

[0038] With step 1 gained ferrous sulfate (FeSO 4 ) solution in a closed container, add sodium carbonate (Na 2 CO 3 ) solution; reaction precipitation, separation and precipitation, to obtain the re...

Abstract

The invention discloses a manufacture method of an anode material of a lithium ion battery, belonging to the manufacture method of battery anode materials. The method takes iron (Fe), sulfuric acid (H2SO4), sodium carbonate (Na2CO3), lithium hydroxide (LiOH) or lithium carbonate (LI2CO3) and phosphoric acid (H3PO4) as raw materials and comprises the steps of preparing ferrisulfas, preparing ferrous carbonate, preparing lithium orthoposphate monometallic and preparing ferrous phosphate lithium anode material. The invention has the advantages of simple manufacturing technique, convenient operation, safety, reliability, pure product, stable quality, low cost and no pollution to environment.

Description

technical field [0001] The invention relates to a method for manufacturing an anode material for a battery, in particular to a method for manufacturing an anode material for a lithium ion battery. Background technique [0002] With the decrease of fossil energy and the increasing attention to the pollution of the environment, finding new clean energy has become a top priority, so the utilization of electric energy has been paid more and more attention by people. However, the use of electric energy on moving objects is very limited, and the only way at present is to use batteries. However, traditional lead-acid batteries have their own shortcomings that cannot be overcome. First, the pollution is serious, and lead and acid are serious pollution sources. The second is self-heavy and small specific capacity. The 3rd, the service life is short, and the times of flushing and discharging are few. In recent years, lithium-ion batteries have developed rapidly, especially the emer...
