Canadian manufacturer Electrovaya has announced a major order for its Separion ceramic composite separators from an unnamed Chinese battery company. Electrovaya acquired the Separion intellectual property from a company called Evonik in April.
According to Electrovaya, most cells made with a graphite anode and a Nickel Manganese Cobalt (NMC) cathode have cycle life between 3,000 and 5,500 cycles, whereas cells with Separion offer up to 9,000 cycles, using the same electrode chemistry and testing conditions.
The Chinese lithium-ion battery company, which subjected Separion separators to intense testing, is expected to buy over $1 million worth of the product in 2015. Several other battery companies have begun qualification processes, says Electrovaya, which estimates that China alone can absorb over $15 million worth of Separion in 2016.
