The role and importance of AGM partitions

Oct , 19 2023

AGM separator and transfer reaction between positive and negative plates Structure and function of partitions The AGM partitions used by VRLA have the following additional functions: Absorb the electrolyte (the third active substance of the battery) so that it does not flow. Provides a relatively large gas transfer hole for oxygen diffusion and thus facilitates the operation of the COC. High ionic...
