May 17 (Reuters) - Electrovaya (EFL.TO), a zero-emission lithium ion battery systems maker, reported a wider quarterly loss as a 59 percent rise in revenue failed to offset stock option expenses and one-time charges incurred in the period.
For the second quarter ended March 31, net loss was $1.2 million, or 2 cents per share, compared with $237,000, or 1 cent per share, a year ago.
Revenue rose 59 percent to $1.1 million.
Electrovaya said it incurred a $0.3 million non-cash stock option expense and $0.1 million in one-time legal and software expenses in the quarter.
