  • Patent number: 10381608
    Abstract: A flat type battery includes an exterior member housing an electrolytic solution and a power generating element. The power generating element contains electrodes alternating layered between electrolyte layers, and expands with use in a layering direction of the electrodes. The exterior member forms a tightly sealed space in which the power generating element is housed, and in which an extra space is formed between the exterior member and a side surface extending along the layering direction of the power generating element. The exterior member includes a volume adjustment portion allowing for an increase in the volume of the extra space by expanding in response to a pressure rise inside the tightly sealed space while the exterior member is being pressed against the surfaces intersecting the layering direction of the power generating element due to a pressure difference between the exterior and the interior.

  • Patent number: 10326126
    Abstract: Provided are a negative electrode active material and a method of preparing the same, and particularly, the present invention relates to a negative electrode active material including a core including natural graphite, and a shell surrounding the core and including a roughened amorphous carbon layer. Since the negative electrode active material according to the present invention has a roughened surface, adhesion may be improved by using a less amount of a binder due to an anchoring effect in which curved surfaces of active material particles in contact with each other are anchored. Thus, an increase in resistance due to the use of an excessive amount of the binder may be prevented while achieving high loading in a negative electrode. Also, since a specific surface area is increased due to the roughened surface, access of lithium ions becomes easy, and thus, high output of a battery may be obtained.
