Abstract

The invention proposes a separator configuration that is beneficial for any type of membrane operation and monitoring. The separator configuration includes embedded conductive filaments within the structure of non-conductive separator material or membrane. The configuration acts as an excitation system, when conductive filaments are turned ON or a monitoring system, when conductive filaments are switched OFF. The scope of the invention applies to electrochemical storage (batteries), fuel cells, filtering systems and the like where a membrane is required.

DETAILED DESCRIPTION

Generally, separators provide a barrier between anode and cathode while enabling exchange of ions from one side of the battery to the other. As depicted in Figure 1, in a conventional battery or fuel cell, separators are manufactured from non-conducting porous materials.

In desalination technique, semi-permeable membrane is usually utilized for osmotic desalination process.

However the conventional techniques are not effective in avoiding accumulation of charge in the vicinity of separator material used in a battery or fuel cell. Also, the conventional separator membrane does not provide efficient desalination or filtering.

Therefore, there is a need for an effective separator membrane that is utilized in a battery, fuel cell or filtering system, among others.


           The invention proposes a separator configuration that is beneficial for any type of membrane operation and monitoring. The separator configuration includes embedded conductive filaments within the structure of non-conductive separator material or membrane. The conductive filaments are thin metallic filaments added into the separator. The filaments are excited with an external electric source in order to produce additional electrochemical effects. For example, filaments are connected either to a direct current (DC), or ADC, or an impulse source. Figure 2 depicts a battery with anode, cathode and separator unit. As depicted in Figure 2, the separator is embedded with thin metallic filaments.
