What are the materials of the positive and negative electrodes of lithium-ion batteries?

Lithium-ion batteries use compounds containing lithium as the positive electrode and carbonaceous materials as the negative electrode.

The positive electrode materials of lithium batteries include lithium oxide and cobalt LiCoO2, ternary materials Ni+Mn+. Co and manganic acid Lithium Li2MnO4 are added with a conductive agent and an adhesive, and are coated on aluminum foil to form a positive electrode. The negative electrode is made of layers of graphite, with a conductive agent and adhesive coated onto a copper foil base strip. The most advanced negative electrode layered graphite particles used nanocarbon.

What is the difference between lithium iron phosphate battery and ternary lithium battery?

Different properties, lithium iron phosphate battery is a lithium ion battery with lithium iron phosphate as a materialcathode; Ternary lithium battery, the battery cathode material is lithium-nickel-cobalt manganate or lithium-nickel-cobalt aluminate ternary cathode material.

With the vigorous development of the new energy vehicle industry, the domestic battery industry is developing rapidly. As a core element of electric vehicles, the configuration of power batteries plays a vital role. Currently, the battery types selected by various automobile manufacturers on the market are roughly divided into two types, one is ternary lithium battery and the other is lithium iron phosphate battery. The differences between the two are as follows.

1. Different properties

1. Lithium iron phosphate battery: A lithium-ion battery using lithium iron phosphate as the positive electrode material.

2. Ternary lithium battery: the cathode material oflithium battery is a ternary lithium-nickel-cobalt or lithium-nickel-cobalt-aluminate cathode material.

2. The main materials are different

1. Lithium iron phosphate battery: The cathode materials of lithium ion batteries mainly include lithium cobalt acid, lithium manganese acid, lithium nickel acid, ternary materials and phosphoric acid Lithium iron, etc. Lithium-cobalt oxide is the cathode material of most lithium-ion batteries.

2. Ternary lithium battery: The ternary composite cathode material is composed of nickel salt, cobalt salt and manganese salt as raw materials. The proportion of nickel, cobalt and manganese can be adjusted according to actual needs. .

3. Different applications

1. Lithium iron phosphate battery: large electric vehicles: buses, electric cars, tourist buses and light electric vehicles : electric bicycles, golf carts, small flat battery carts, forklifts, cleaning vehicles, electric wheelchairs, etc. power tools: electric drills, chainsaws, lawn mowers, etc.

2. Ternary lithium battery: widely used in mobile and wireless electronic equipment, power tools, hybrid and electric vehicles and other fields.
