| titleOfInvention | A kind of ultra-low temperature battery capacitor and its preparation |
| abstract | The invention relates to an ultra-low temperature battery capacitor and a preparation method thereof, belonging to the technical field of new energy energy storage. The capacitor battery of the invention includes a positive electrode sheet, a negative electrode sheet, and a low-temperature electrolyte. The positive electrode material coated on the positive electrode sheet is compounded by nanoscale lithium electric active material, nanoscale porous carbon material, positive electrode binder and positive electrode conductive agent. The coated negative electrode material is composed of graphite and nano-scale porous carbon composite material, negative electrode binder and negative electrode conductive agent, and the low-temperature electrolyte is composed of multi-component solvent, composite electrolyte salt and additives. The battery capacitor of the invention can work at ‑40°C, has high low-temperature charge-discharge efficiency, good low-temperature rate performance and cycle stability, and does not affect its high-temperature performance. In the preparation process, moisture and surface functional groups are strictly controlled to effectively improve the battery Charge-discharge efficiency and cycle life of capacitors at low temperatures. |
