DGAP-Adhoc Leclanché / Saint-Gobain: Joint Press Release

Joint Press Release

Leclanché and Saint-Gobain announce a joint development agreement to
co-develop and market a new ceramic separator for lithium-ion cells

Yverdon-les-Bains, Switzerland, Worcester, Massachusetts, United States,
June 10th, 2014 - Leclanché S.A. (SIX Swiss Exchange: LECN), specialized in
the production of large-format lithium-ion cells and energy storage
solutions and the Saint-Gobain division specialized in the research,
development, and manufacturing of high-performance material films,
ceramics, slurries, and inorganic material, today announced that they have
entered into a collaboration agreement to co-develop a new ceramic
separator for use in lithium-ion batteries, which if successful, will be
used by Leclanché in its stationary product range and marketed by
Saint-Gobain for use in other lithium-ion cells markets.

A joint collaboration to develop the next generation separator

Leclanché and Saint-Gobain have agreed to a collaboration program, which
aims to develop a new separator material for use in lithium-ion batteries.
Leclanché has already successfully developed and patented a proprietary
ceramic separator that is manufactured by Leclanché in its factory in
Willstaett, Germany, and that is currently incorporated in Leclanché's
lithium-ion titanate cells. The separator is a key element of the cell
construction as it forms a strong barrier between the anode and cathode
materials, the two main active components of a cell. The ceramic structure
of the separator developed by Leclanché is a key safety feature of its
lithium-ion titanate cells.

Under the collaboration agreement, Leclanché will outsource the manufacture
of the existing separator to Saint-Gobain followed by the co-development of
an enhanced separator material leveraging Leclanché's technology and
Saint-Gobain's strong technology platform in polymers and inorganic grains
and powders. The objective is to create a new separator with performance
advantages.

Pierre Blanc, Leclanché's Chief Technical Officer commented: "I am
delighted that we have concluded this joint development agreement with
Saint-Gobain, whose depth and breadth of experience and capability in
polymers and fluoropolymers is world class. Through this program we aim to
develop the next generation separator, consistent with our product road map
to reduce costs and enhance cell performance without compromising safety."
