Competitive edge through innovation: the Leclanché separator

Leclanché large capacity lithium-ion batteries have a decisive competitive edge over all other lithium-ion batteries currently available: they use a patented ceramic based battery separator, the Leclanché Separator. In it, an ion conducting material serves as a solid electrolyte. This ceramic material is uniformly dispersed in a polymer matrix, creating a separator with a unique combination of thermal stability and excellent flexibility.

• Added battery safety
  The innovative combination of polymer and ceramic materials used in the Leclanché Separator serves as a shut down mechanism. It will close the separator pores, if the cell is exposed to high heat resulting from an overcharge or an internal or external short circuit. In this way it will physically isolate the electrodes to avoid any further danger.
• Reliable operation even in extreme conditions
  The thermal stability of the innovative combination of polymer and ceramic materials used in the Leclanché Separator ensures that the separator will not decompose or shrink when exposed to heat or in extreme situations. This means better cell stability in operation, considerably reduced failure propagation within the cell, and an all together safer cell.
• Reproducible production processes
  The use of the innovative polymer matrix gives the Leclanché Separator an unparalleled production flexibility and mechanical stability allowing it to be safely used on the production machines without any risk of cracks or pinholes caused by mechanical stress or bending.
• Excellent cost efficiency
  The high flexibility and reliability of the innovative Leclanché Separator ensures a very low failure rate in production and a long lifetime of the battery, resulting in an excellent cost efficiency for the user.
