Abstract

The invention relates to a lithium ion battery mainly taking manganese, nickel and titanium as anode and cathode materials and aluminum foils as anode and cathode collectors, and a preparation method thereof. In the manganese, nickel and titanium lithium ion battery, a cathode consists of lithium manganate, a ternary composite material, other solid mixtures of the cathode, and a cathode solvent; and the anode consists of nano lithium titanate, other solid mixtures of the anode, and an anode solvent. Compared with the prior art, the novel lithium ion battery has the advantages of strategically long service life, good electrical property, low cost, safety and environmental friendliness; and the prepared batteries are soft package and steel shell lithium ion batteries and polymer lithium ion batteries.

Description

technical field [0001] The invention relates to a lithium-ion power battery mainly using manganese, nickel, and titanium series as positive and negative electrode raw materials, and aluminum foil as a positive and negative electrode current collector and its preparation method, especially a lithium ion power battery with long cycle life, good high and low temperature performance, A safe, reliable and low-cost lithium-ion power battery and a preparation method thereof. Background technique [0002] Energy and the environment are extremely important material foundations for the survival and development of human society. Since the formation of energy systems based on fossil fuels such as oil, coal and natural gas, countries around the world have greatly promoted the prosperity, progress and development of human society. However, with the painful lessons of various unfortunate disasters encountered by countries in the world today and the continuous improvement of human scientif...
