16-05-06 Rechargeable lithium air batteries are a next-generation technology: Theoretically they might be much lighter and offer better performance than current lithium ion batteries. However, currently they run out of steam after only a few charging cycles....

14-05-21 The long life of lithium ion batteries makes them the rechargeable of choice for everything from implantable medical devices to wearable consumer electronics. But lithium ion batteries rely on liquid chemistries involving lithium salts dissolved in...

13-07-18 Polarisability determines the force with which an inhomogeneous（不同类的） external electric field acts on the ions of an ion beam. However, it can be quite tricky to obtain accurate values for this force. Now, two German theoretical chemists, Volk...

10-08-13 A little wax（蜡） and soap can help build electrodes（电极，电焊条） for cheaper lithium ion batteries, according to a study in August 11 issue of Nano Letters. The one-step method will allow battery developers to explore lower-priced alternatives...

09-10-30 Direct communication between Earth and Mars can be strongly disturbed（扰乱，妨碍） and even blocked by the Sun for weeks at a time, cutting off any future human mission to the Red Planet. An ESA engineer working with engineers in the UK may have fo...
