The theoretical capacity of the electrode material, that is, the capacity that can be provided by the assumption that all lithium ions in the material participate in the electrochemical reaction, and the value is calculated by the following formula: Theoretical capacity（mAh/g）=Faraday constant F(C/mol)*1/Molecular weight(mol/g)*1/3.6(mAh/C) Wherein, the Faraday constant (F) represents the charge per mole of electrons, in units of C/mol, which is the product of the Avogadro number NA=6.02214 × 1023 mol-1 and the elemental charge e=1.602176 × 10-19 C. Its value is 96485.3383±0.0083 C/mol. Therefore, the mainstream material theoretical capacity calculation formula is as follows: LiFePO4 has a Molar mass of 157.756 g/mol and its theoretical capacity is: Theoretical capacity（mAh/g）=96500(C/mol)*1/157.756(mol/g)*1/3.6(mAh/C)=170mAh/g We are TOB , we are not only provide the materials of the battery,but also provide the knowledge of battery.

The electrolyte function of the lithium battery is to conduct ions between the positive and negative electrodes, and acts as a medium for charging and discharging, just like the blood of the human body. Lithium battery injection can be divided into two steps:filling and infiltration.Infiltration is a more critical and difficult step.During this step,electrolyte is diffuse at electrode.There are three force interactions in this process:the pressure Fi from the electrolyte flow, the capillary force due to the surface tension Fs, and the resistance Fg generated by the air in the hole.So,Vacuum-pressure filling is beneficial to electrolyte infiltration.When filling the electrolyte, vacuuming the battery can reduce the resistance generated by the air, while pressurizing the electrolyte can increase the driving force of the liquid flow.  Our filling machine can help us achieve the filling effect that we want(Our liquid filling machine can help us achieve the liquid injection effect we want.).  We are TOB ,we are not only provide the machine of the battery,but also provide the knowledge of battery.

Ball mill is a popular way to process the materials.Ball mill is through the collision between balls to grind the materials,which can give the materials a smaller particle size and change the activity of the surface of the materials.Nowadays, many lithium battery anode materials in the world need to be processed by ball milling, especially the now popular silicon-based anode materials. We are TOB , we can supply the world's top ball mill and others equipment of battery.Choose us is choose best equipment and best service.  Contacts: Miss carol(Sales&Engineer) E-mail:tob.mae@tobmachine.com Skype:583432443@qq.com WeChat: TOB-005
