LG Chem has warned rival firms against breaching its intellectual property rights to key lithium ion polymer battery technologies.
Speaking at a press conference in Daejeon, LG Chem’s chief of battery research Kim Myung-hwan said competitors are using the company’s SRS technology and that such developments could become an issue.
Developed by LG Chem, SRS is a separator with a thin coating of ceramic materials for increased structural integrity.
The separator is a component made from polypropylene or polyethylene that separates the anode from the cathode. If the separator is damaged, the efficiency of the battery can be diminished or a fire may result.
Kim said, rival firms have taken to applying the method despite their earlier doubts about the need for such a device.
Kim also said that a rival company has even announced that they developed the technology independently.
Kim did not mention any company by name but said that practically all lithium ion polymer battery makers are involved.
In addition, Kim said that LG Chem’s stack and folding technology could also lead to legal disputes.
The technique stacks the anode, separator and cathode before folding them instead of the conventional winding method that rolls the materials together.
The news conference was held while the company opened its plant in Ochang Scientific Industrial Complex in North Chungcheong Province to the media for the first time on Friday.
The plant, the works on which began last July, went into operation in June. The plant is capable of producing 8.5 million cells on an annual basis, which is sufficient to power 400,000 Avante LPi hybrid vehicles.
The company is currently expanding the plant’s production line, and plans to inject 1 trillion won ($886 million) by 2013 to raise the Ochang plant’s production capacity to 60 million cells.
Including the company’s overseas production facilities, the company will be able to produce 80 million cells on an annual basis.
