In recent years, along with the universal and miniaturization of the portable machines such as mobile phone, notebook computer, the battery with nonaqueous electrolyte such as lithium battery are progressively used as its power supply.And from tackling nearest environmental problem, the traction-type cell using it as electric automobile etc. also causes concern gradually.As positive pole active material for lithium cell, conventionally extensively adopt LiCoO 2(cobalt acid lithium) is as the material that can form 4V level battery.Use LiCoO 2during as positive active material, discharge capacity is about 160mA/g, is practical as LiCo0 2the cobalt of raw material be scarce resource, and skewness, so Expenses Cost, raw material supplying is unstable.
Summary of the invention
Goal of the invention: the present invention is directed to the deficiencies in the prior art, propose a kind of use and can give lithium battery a kind of positive pole active material for lithium cell manufacture method of excellent cycle characteristics especially.
Technical scheme: a kind of positive pole active material for lithium cell manufacture method, described manufacture method is first by lithium compound, the mode that the compound that comprises nickle atom, cobalt atom and manganese atom and titanium oxide are 1.08-1.12 according to lithium atom with respect to the atomic ratio Li/{Ni+Co+Mn+Ti} of nickle atom, cobalt atom, manganese atom and titanium atom is mixed, and calcining; Again the resulting lithium composite xoide of calcining is milled into powder, invests lithium battery anode surface, after energising, be just adsorbed in lithium battery anode surface.
As preferably, described nickle atom: cobalt atom: the atomic ratio of manganese atom is 1:0.5～1:0.5～5.
As preferably, described calcining heat is 800-1200 ℃.
As preferably, described in comprise nickle atom, manganese atom and cobalt atom compound be cohesion shape complex hydroxide.
Beneficial effect: utilize manufacture method of the present invention simple, this positive active material can be manufactured by industrial favourable method, convenient succinct.
