*This abstract for appeared for patent application  number 18210123 Titled 'METHOD OF PRODUCING LITHIUM ION SECONDARY BATTERY AND NEGATIVE ELECTRODE MATERIAL'

==Simplified Explanation==

The abstract describes a method for making a lithium-ion secondary battery. The method involves creating an electrode body with a positive electrode and a negative electrode. The negative electrode contains a special type of graphite particle with open pores, and these pores are filled with SiO. The next step is to assemble the battery by combining the electrode body with a non-aqueous electrolytic solution that contains LiPF at a concentration of at least a certain value. Finally, the battery generates lithium difluorophosphate within the electrode body.


==Original Abstract Submitted==

A method of producing a lithium ion secondary battery includes preparing an electrode body which includes a positive electrode and a negative electrode and in which the negative electrode contains a negative electrode material containing a porous graphite particle having open pores and SiOdisposed in the open pores, producing a battery assembly including the electrode body and a non-aqueous electrolytic solution containing LiPFwith a concentration of  mol/L or more, and generating lithium difluorophosphate in the electrode body
