By Catherine Zandonella GENETICALLY engineered viruses that assemble into electrodes have been used to make complete miniature rechargeable batteries for the first time. The new lithium ion batteries are as powerful as existing devices but smaller and cleaner to make, claim the team behind the work. The technology could improve the performance of hybrid electric cars and electronic gadgets. Lithium ion batteries exploit the reactivity of lithium to produce a current. Inside the battery, lithium ions move from the anode to the cathode,
