Abstract
The invention discloses a battery, a terminal and a manufacturing method of the battery. The battery comprises a shell, a plurality of pole pieces, isolating membranes and electrolyte, the pole pieces are arranged in the shell at intervals, the isolating membranes are arranged in the shell and located between every two adjacent pole pieces, the electrolyte is arranged in the shell and fills gaps between the pole pieces and the isolating membranes, and the density of the electrolyte is 1.1 g / cm < 3 >-1.3 g / cm < 3 >. In the battery provided by the embodiment of the invention, the density of the electrolyte is 1.1-1.3 g / cm < 3 >, the electrolyte is a low-density electrolyte, and on the premise of keeping the original structure and size of the battery unchanged, when the mass of the electrolyte is the same, the volume of the electrolyte injected into the shell is larger, and the occupied volume in the battery cell is larger, so that the battery performance is improved. Gaps between the isolating membrane and the pole piece and gaps between the isolating membrane and the pole piece can be better filled, and the infiltration effect is better.
Description
technical field [0001] The present application relates to the technical field of battery devices, and more particularly, to a battery, a terminal and a method for manufacturing the battery. Background technique [0002] Lithium-ion batteries are widely used in the field of energy storage due to their high energy density, operating voltage, wide operating temperature and cycle life. The PP separator has the advantages of uniform thickness, strong flexibility, high tensile strength, not easy to break, and low cost, and is widely used in lithium-ion batteries. However, in the related art, there is no adhesive force between the PP separator and the pole piece, and it is necessary to ensure a sufficient amount of electrolyte injection to fill the gap between the separator and the pole piece, thereby ensuring the pole piece interface. However, increasing the injection volume will increase the manufacturing cost and reduce the energy density. SUMMARY OF THE INVENTION [0003] E...
