A rechargeable battery (10) includes an electrode assembly (110) including a first electrode plate (111), a second electrode plate (112), and a separator (113) between the first and second electrode plates, an electrolyte having viscosity of about 1 Pa·s to about 15 Pa·s at a temperature from about 20°C to about 25°C, a can (120) having an opening (OP) on one surface through which the electrode assembly (110) is inserted, the electrode assembly and the electrolyte being accommodated inside the can, and a cap plate (130) that seals the opening (OP) of the can (120). A ratio of the height (h1) of the can to a cross-sectional area being the product of the thickness (Y-direction) times the width (X-direction) of the can (120) is from about 12.5% to about 25%, thereby increasing the impregnation efficiency of electrolyte. |
