Dec 6 (Reuters) - Talison Lithium Ltd said on Thursday it is now backing a sweetened takeover bid from China's Chengdu Tianqi Industry Group Co, which values the lithium producer at C$847 million ($853.01 million).
Shares of the Perth-based, Toronto-listed miner rose more than 6 percent Thursday morning but were still below the revised Tianqi offer of C$7.50 per share.
The revised bid is higher than Tianqi's earlier offer of C$7.15 per share and 15 percent higher than a competing C$6.50 per share bid from chemical producer Rockwell Holdings Inc , which valued Talison at C$724 million.
The Talison board said it now recommends that shareholders accept the Tianqi offer, in the absence of a new bid from Rockwell.
Talison recently completed an expansion at its flagship project in Australia and now has the capacity to produce nearly two-thirds of current global demand for lithium carbonate, which is used in batteries for technology items like smartphones and hybrid cars.
Shares of Talison were up 6.84 percent at C$7.34 Thursday morning on the Toronto Stock Exchange.
