It's all about supply and demand: According to Hideo Takeshita, an analyst at the Institute of Information Technology Ltd. in Tokyo, the price of lithium-ion batteries could drop by about 19% in 2010, while another analyst, Shiro Mikoshiba of Nomura Holdings, said that the worsening oversupply may push prices down as much as 25%.
