翻译如下：

Silicon is the most likely alternative graphite anode materials of lithium ion batteries, because silicon has a large capacity (Li4.4Si alloy was 4200mAh / g ).

lithium intercalation potential is low ( below 0.5V) and an electrolyte and has the advantages of low reaction activity.

But the silicon particles in the insertion / extraction process generates intense volume change, making silicon particle powder electrode failure, rapid attenuation.

Through the pyrolysis tar or polyvinyl chloride ( PVC ) preparing a silicon / carbon composite can significantly improve the cycle performance of material, the carbon to volume changes can effectively buffer, thereby inhibiting capacity attenuation.

and the carbon has small volume expansion, good conductivity, light weight and so on are closely related.

英语学习方法

第一：自信的说英语。

英语是一门语言，最重要的事说出口，很多同学学习英语的时候不敢说出来，怕人家笑话，虽然学的很好，却成了“哑巴英语”。要想学好英语，那就勇敢自信的说英语，慢慢的锻炼中，英语语感有了，英语自然就学好了。

第二：经常的听英语。

英语听力刚开始的时候确实是很痛苦的，听不懂，也做不对，就像放弃。其实只要坚持下去，在听的时候集中注意力，认真听，坚持一段时间就会收到很好的效果。

Silicon is most likely to replace the graphite lithium ion battery cathode materials because one of the large capacity of silicon has (generation Li4.4 Si alloy for 4200 mAh/g when), intercalated-li potential low (0.5 V and and electrolyte reaction activity etc. But silicon particles in the process of lithium embedded/take off the volume change violently, makes the silicon powder particles of failure, electrode capacity fast attenuation. Through the pyrolysis asphalt or polyvinyl chloride (PVC) preparing silicon/carbon composite material can improve the performance of the material circulation, show that the carbon on volume change can be effectively buffer, and rein in capacity attenuation, and this is the volume and carbon expansion and electric conductivity small, light material advantages such as closely related.

Silicon is the most likely to replace the graphite anode material for lithium-ion battery is one of the (generated Li4.4Si alloys because silicon has a large capacity of 4200mAh / g), embedded lithium (0.5V) and low activity with the electrolyte reactionand so on. Silicon particles have a dramatic volume change in the process of intercalation / deintercalation of lithium, making silicon granular powder failure, fast decay of discharge capacity. Prepared by pyrolysis of bitumen or polyvinyl chloride (PVC) silicon / carbon composite can significantly improve the cycling performance, indicating that the carbon can effectively buffer the volume change, thereby inhibiting the capacity fading and the volume of carbon expansion is small, the advantages of good conductivity, light weight are closely related.
