| titleOfInvention | Battery core of secondary battery and preparation method of battery core |
| abstract | The invention discloses a battery cell of a secondary battery, which comprises a positive plate, a negative plate, an isolating membrane and electrolyte, wherein the isolating membrane is arranged between the positive plate and the negative plate, the positive plate and the negative plate both comprise porous current collectors, and each porous current collector is internally provided with an NTC material body; an NTC material body is arranged in each hole of the porous current collector and is in seamless fixed connection with the inner wall of each hole of the porous current collector; a preparation method of a battery cell comprises the following steps: after the NTC material body is softened by sintering, pressing the NTC material body in each hole of the porous current collector by adopting cold pressing; finally, manufacturing the porous current collector containing the NTC material body into a pole piece; placing an isolating membrane, injecting electrolyte, and assembling into a battery cell; the invention not only ensures the low-temperature heating characteristic, but also does not cause the performance reduction of the battery due to the addition of the NTC material, and can save the space; the body of the secondary battery can be kept in a heating state for a long time when the secondary battery is used at low temperature, and the performance of the secondary battery can be exerted. |
