The key role of —— soda ash in new energy batteries

New energy battery refers to the use of hydrogen fuel cell, lithium-ion battery and other new battery technologies to replace the traditional battery technology used in fuel vehicles. In the production process of new energy batteries, soda ash is widely used in the positive electrode, negative electrode, electrolyte and other links.

What is the use of soda ash to make new energy batteries?

New energy battery refers to the use of hydrogen fuel cell, lithium-ion battery and other new battery technologies to replace the traditional battery technology used in fuel vehicles. In the production process of new energy batteries, soda ash is widely used in the positive electrode, negative electrode, electrolyte and other links. Specifically speaking, it includes the following links:

1.Positive electrode coating The positive electrode is one of the core components of new energy batteries. Positive electrode coating is the process of coating a cathode material onto a substrate. Among them, soda ash needs to be added to the coating to adjust the PH value to ensure the uniformity of the coating and improve the performance of the battery.

2.Negative electrode coating The cathode material generally uses graphite, and the cathode coating is the process of coating the cathode material on a substrate. In the negative electrode coating process, adding soda ash can control the colloidal stability of the coating, improve the uniformity of the coating, prevent oxidation and hydrolysis, and thus improve the performance of the battery.

3.Electrolyte Electrolyte is the conductive medium of the new energy battery, which is generally composed of lithium salt and organic solvent. In the electrolyte, the addition of soda ash can adjust the PH value and improve the electrochemical performance of the battery.

Why is soda ash used in new energy batteries?

1.Adjust the PH value Positive and negative electrode coating and soda ash were added to the electrolyte to regulate PH. Soda ash can neutralize acidic substances, making the PH value in the appropriate range, thus ensuring the performance of the battery.

2.Improve the battery's performance Adding soda ash can improve the performance of the battery, including its cycle life, power density, energy storage density and so on. At the same time, soda ash can also improve the stability and safety of batteries.

New energy battery is the direction of the future development, and soda ash plays an important role in it.soda ash adjust PH value, improve battery performance, ensure the stability and safety of the battery, are very critical links.
