A Chinese company has developed a light-powered mobile phone which could mean an end to drained batteries.
Beijing-based Hi-Tech Wealth spent seven years developing the device, S116, which transforms light into electricity and stores it in its lithium battery.
A report on the website of Xinhua news agency says a one-hour exposure to sunlight can power 40 minutes of talk time. When the stored electricity is finished, another five-minute sunlight-recharge lets the phone work as normal.
The gadget also works in weaker light such as indoors and by candle light.
Zhang Zhengyu, Hi-Tech Wealth chief executive, says the invention could reduce environmental pollution caused by used batteries.
He also claims the solar-powered battery has a longer lifespan than traditional types.
The mobile phone sells for 3,980 yuan (US$521).
北京恒基伟业公司花了七年时间开发这款S116手机,它能将光能转化为电能储存在锂电池中.据新华网报道,用太阳光充电一个小时可以通话40分钟.当储存的电量用完后,再次充电5分钟,可手机再次恢复正常工作.恒基伟业公司董事长张征宇说此装置在弱光下也可以充电,比如室内,或者烛光,这项发明可以减少由废电池产生的环境污染.他还说,光能电池要比普通电池的寿命长.这款手机售价3,980元(折合521美圆).
