That brings it much closer to the timeframe needed for hybrid car batteries , ceder said .
由此其也将大大接近于混合动力汽车电池要求的时间范围,希德说。
What dr ceder and mr kang have done is create electrodes that are made of two different materials , one of which is good at storing ions while the other is good at conducting them .
Gerbrand ceder and byoungwoo kang of the massachusetts institute of technology hope to change this , and thus help make the electric car a work-a-day consumer item , rather than a high-end boy 's toy .
The great prize in the battery world has thus been a material that can both store a lot and discharge rapidly , and it is this that dr ceder and mr kang think they have come up with .
