Graphene Apply to Lithium Batteries

How to make graphene:
First, pour some graphite powder into a blender. Add water and dishwashing liquid, and mix at high speed. Congratulations, you just made the wonder material graphene. This surprisingly simple recipe is now the easiest way to mass-produce pure graphene – sheets of carbon just one atom thick.

Highlights
•The use of graphene in lithium ion battery cathode materials has been reviewed.
•Graphene improves electron conductivity of lithium ion battery cathode materials.
•Graphene nanosheets form an electron conducting network within the cathode.
•Graphene composite cathodes have superior rate capability and cyclability.

Abstract
Graphene is a relatively new and promising material, displaying a unique array of physical and chemical properties. Although considered to be especially promising for the use in energy storage applications, graphene has only recently been implemented as an electron conducting additive for lithium ion battery cathode materials. In current studies graphene is found to significantly improve cathode electrochemical performance. As the charge capacity, rate capability and cyclability of lithium ion batteries are still in ever-remaining need of improvement, this article examines the prospects of graphene implementation into lithium ion battery cathodes to meet such demands. The existing literature and recent advances on the topic have been reviewed, covering the preparation of graphene and graphene composite lithium ion battery cathodes, their structure and electrochemical properties along with underlying principles for electrochemical performance enhancement of such materials.

Hydraulic Coin Cell Crimping Machine For Lab Researching

TOB-MR-120 coin cell crimper is a newly designed coin-cell sealing machine with lighter weight.

This Coin Cell Crimping Machine is suitable for sealing various types of coin cells such as CR2032,CR2025,and CR2016 with adjust the sealing line and without changing the die.It can also crimp CR2325, CR2450, AG3, AG5 and other special size cases with optional die sets. In addition, customers can easily replace the original die for disassembling purpose.It can also be worked in glove box with smaller volume.

Advantage:

1 The lower die with high precision positioning ring spcing, control the battery packge height

2 The upper die is provided with a seling cup inner screw spring mechanism,ensure in case the battery sealing clamp can not be removed,only the top screw clockeise and the button battery out.

3.By using aluminum alloy and high strength steel,surface after the environmental protection electroplating processing will never  rust.
