What is the application and difference of electrode paste in different types of batteries?

Electrode paste is a conductive material used in battery manufacturing, and its application and difference in different types of batteries are mainly reflected in the following aspects:

1. Lead-acid battery: electrode paste is mainly used to manufacture positive and negative plates in lead-acid batteries. The electrode paste on the positive plate mainly contains lead oxide, while the electrode paste on the negative plate mainly contains spongy lead. Lead-acid batteries have the advantages of stable voltage and low price, but their energy density is low, and they are not suitable for high energy density occasions.

2. Nickel-metal hydride battery: Electrode paste is mainly used to manufacture positive and negative electrodes in nickel-metal hydride batteries. The electrode paste on the positive electrode mainly contains nickel hydroxide, and the electrode paste on the negative electrode mainly contains hydrogen storage alloy. Nickel-metal hydride batteries have high energy density and cycle life, but their cost is high and their performance is poor at low temperatures.

3. Lithium-ion battery: electrode paste is mainly used to manufacture positive and negative electrodes in lithium-ion batteries. The electrode paste on the positive electrode mainly contains lithium cobalt oxide, lithium nickel cobalt aluminum oxide, etc., and the electrode paste on the negative electrode mainly contains graphite. Lithium-ion batteries have high energy density, good cycle life and low temperature performance, but their cost is high and the manufacturing process is strict.

4. Fuel cells: Electrode pastes are mainly used to manufacture anodes and cathodes in fuel cells. The electrode paste on the anode mainly contains catalysts such as platinum, and the electrode paste on the cathode mainly contains catalysts and conductive agents. Fuel cells have the advantages of high energy density and no pollution, but they are expensive and require continuous fuel supply.

In short, the application and difference of electrode paste in different types of batteries are mainly reflected in the conductive materials used, battery performance and application fields. Different types of batteries according to their performance requirements and cost considerations, select the appropriate electrode paste for manufacturing.
