TREATED BATTERY SEPARATOR |
摘要 |
In at least one embodiment, a rechargeable battery is provided comprising an electrolyte including an organic solvent and a solution-treated polyolefin separator. A contact angle of the electrolyte including the organic solvent upon the separator may be from 0 to 15 degrees. In one embodiment, the solution-treated polyolefin layer has an increased concentration of ionic functional groups at its surface compared to an untreated polyolefin layer. In another embodiment, the solution-treated polyolefin separator has been treated with a treatment solution having a pH of either at most 2 or at least 12. The separator may be treated with an acid or base solution for at least 30 seconds. The solution-treated separator may exhibit improved wetting with an electrolyte compared to an untreated separator. |
