Electric cars are supposed to help the world go green and stop hurting the planet. Engineers at Brown University and the University of Maryland are taking that goal to another other level, with a new idea for batteries made from trees, according to new findings published in Nature. Lithium-ion batteries (锂电池) have become the new form of rechargeable batteries thanks to their extraordinarily long charge. You're probably reading this story from a device powered by such a battery. Most electric cars like ones made by Tesla use lithium-ion batteries. These batteries use a liquid solution that conducts lithium ions from the battery's cathode and anode (阴极和阳极), but the liquid is not what helps ensure electrical power goes from the battery to the device it's powering. The problem is that this liquid is made of harmful materials that are sometimes unstable. They sometimes have explosive results. A solid conducting structure would prevent this from happening, but it could be likely to crack and break, making the battery useless. An ideal material for solid state lithium-ion batteries would be thin and flexible to resist structural stresses, and it is wood from a tree. The team in charge of the new research developed a mixed material made of copper (铜) and fibers coming from wood. They tested it out as a model for conducting ions back and forth in a lithium-ion battery, and found it works 10 to 100 times better than other solid-state conductors-a record high. The new findings are just based on basic model tests, and a rechargeable battery made of trees is still quite a way off. But if it passes test as a practical form of energy, it can very well replace rechargeable batteries. It is not hard to imagine electric cars having better sales for their real green, but saying that their batteries are just made from trees is beyond our imagination.

Good morning. This is Paul's repairs and supplies. What can I do for you today?<br />Hi, Paul. This is Cindy from 222 Avenue again. Do you remember fixing my bathroom sink two weeks ago?<br />Yes, I do. It was leaking constantly, wasn't it?<br />Yes.<br />How is it doing now?<br />Oh, it hasn't leaked since, but I have another problem now.<br />What is it?<br />There is a leak coming from the ceiling in my kitchen.<br />Hmm, if I remember correctly, your kitchen is directly under your upstairs bathroom, isn't it?<br />Yes, that's right.<br />Well, it seems the two problems could be related. In fact, I'd bet that they must be because of an object that is blocking a pipe somewhere else in the house.<br />Can I come by around three this afternoon to check it out?<br />That would be great. I won't be home, but my husband David will be there.<br />Okay. Don't forget to keep your dogs locked up. My assistant is afraid of dogs.<br />Don't worry. I'll take them over to my neighbor, Andy's.<br />Thanks.<br />Good morning. This is Paul's repairs and supplies. What can I do for you today?<br />Hi, Paul. This is Cindy from 222 Avenue again.
