Electrovaya Inc., which recently completed the acquisition of Evonik Litarion GmbH and the licensing of the ceramic composite separator SEPARION intellectual property from Evonik (earlier post), has received an order for SEPARION from a leading Chinese battery company. SEPARION, with its high temperature properties, imparts improved safety and cycle life to lithium-ion batteries.
In cells made with graphite anode and NMC cathode (Nickel Manganese Cobalt oxide), most manufacturers show cycle life in the region of 3000 to 5500 cycles with full 100% charge discharge at 1 C rate. Cells with SEPARION show ~9000 cycles using the same electrode chemistry and testing conditions.
Recent developments for SEPARION include:
The Chinese lithium ion battery company qualified SEPARION after intense testing for use in its electric vehicle program. This customer’s requirement is expected to be greater than $1 million in 2015 and growing to larger amounts in 2016.
SEPARION was exclusive to a leading German automotive company for its electric vehicle production. This auto company continues to be a major customer but no longer has exclusive rights.
Several major battery companies are expressing great interest and have begun qualification processes. Electrovaya estimates that China alone can absorb over $ 15 million of SEPARION in 2016.
Electrovaya has also qualified the material and has begun using it for all its own major Li-ion products.
