摘要： The disclosure discloses a battery and a battery apparatus. The battery includes two opposite first surfaces and four second surfaces disposed around the first surfaces, a pole assembly and a busbar. An area of the first surface is larger than an area of the second surface. The pole assembly is disposed on the first surface. The busbar is bent into a first segment and a second segment. The first segment is located at a side of the first surface where the pole assembly is disposed and is connected to the pole assembly. The second segment is parallel to or substantially parallel to a second surface and is used for electrically connecting the pole assembly of another battery.

摘要： The invention discloses an electrolyte solution containing lithium salt, an organic solvent, and additives. The additives include vinylene carbonate and 2,6-di-tert-butyl-4-methylphenol; the content of vinylene carbonate accounts for 0.5% to 5% of the total mass of the electrolyte, and the content of 2,6-di-tert-butyl-4-methylphenol accounts for 7*10−4% to 1.6% of the total mass of vinylene carbonate. The electrolyte of the invention can improve the film formation rate and film thickness of vinylene carbonate in the negative electrode, so that the obtained SEI film resistance is smaller, thereby improving the performance of the lithium battery.
