Stanford University researchers recently said that they have developed a new type of lithium-ion battery, can ensure that the notebook life of 20 hours. According to developers, the current lithium-ion batteries are used to store carbon lithium-ion, and therefore limited capacity. The new lithium-ion battery is used to store a silicon capacity greatly. The adoption of the technology, the new lithium-ion battery life notebook PCs can ensure 20 hours. At present, ordinary laptop battery life about two hours. It is learnt that the new lithium-ion batteries can be applied in addition to laptops and MP3 and other consumer electronics products, can also be used to drive cars, or store the sun for office.
