El agua ultrapura juega un papel crucial en el proceso de producción de baterías de nueva energía, y se aplica principalmente en la preparación de materiales para baterías, la formulación de electrolitos y la limpieza de baterías, para garantizar el rendimiento y la seguridad de las baterías.

Ultra-pure water is applied in the battery industry, including the production of storage batteries, lithium batteries, solar cells, and battery plate grids,etc.

The water used in the electrolyte of batteries has very strict requirements. Generally, the conductivity of water should be less than 0.1 us/cm (resistivity over 10 megohms).

The traditional process for making ultra-pure water for batteries is the ion exchange equipment with both anion and cation resins. The disadvantage of this process is that the anion and cation resins need to be regenerated frequently. With the maturation of membrane separation technology, the current processes for making ultra-pure water are more often reverse osmosis + mixed bed ion exchange, OR reverse osmosis + electro-deionization (EDI).

The following is the main parameters of ultra-pure water for new energy batteries:
