The Development of High-Power LIBs Separators

Figure 1. The cellulose separators in the LIBs. To improve the high-temperature resistance, the existing separator materials can be modified by thermal resistant materials. On the other side, the new high-temperature-resistant materials can be directly used as the

Impact of Battery Separators on Lithium-ion Battery Performance

For a given battery canister, increasing the separator thickness reduces the packed volume of the electrode materials, which consequently reduced the battery discharge capacity (see Fig. 3.3b). In addition, increasing separator thickness from 5 to 100 µm results in increased internal resistance of the battery [59].
