Lithium-ion batteries since first commercially developed for portable electronics in 1991 are now ubiquitous in daily life, in increasingly diverse applications including electric vehicles, power tools, smart devices, cordless appliances.

For lithium-ion battery products, durability (long lifespan), endurance (long working time), and fast charging (short charging time) have increasingly become key factors for customers in choosing end products. Especially in the fields of new energy vehicles and mobile phone products, the length of working time and the quality of fast charging performance have become the selling points of the products' core features.

In addition to increasing the capacity of lithium-ion battery products, selecting better auxiliary functional materials is a cost-effective solution to improve their battery life. The electrode binder is one of the important auxiliary functional materials in lithium-ion batteries. Although it does not have a capacity and occupies a small proportion in the battery, it is the main source of mechanical performance of the entire electrode and has an important impact on the production process of the electrode and the electrochemical performance of the battery.

Three reasons why DIC's aqueous anode binde canachieve long-life performance

Excellent expansion 1 suppression effect
