Sony has unveiled a paper-powered battery prototype in Japan, BBC reported.

The technology generates electricity by turning shredded paper into sugar which in turn is used as fuel.

If brought to market, the innovation could allow the public to top up the power of their mobile devices using waste paper.

The team behind the project said such bio-batteries are environmentally friendly as they did not use harmful chemicals or metals.（點擊英國廣播公司網站查看原文）

環保電池讓廢紙變能源

?????? 據英國廣播公司報道，日本索尼公司發明了一款能夠將廢紙轉化為能源的電池。

?????? 這一技術可以將碎紙張中的纖維素分解為葡萄糖，而這正是其轉化為能源的原料物質。

?????? 如果將其投放市場，這款將廢棄材料轉化為能源的電池可以用來給電子移動產品充電。

?????? 新型電池開發小組稱，這款生物電池非常環保，因為其原料都不是有害的化學產品和金屬。
