- Example 1.1 From the comparison of Example 1.1 to Example 1.12, it can be seen that increasing the amount of carboxylate significantly improves the float charge of the battery at 45°C. This is because the carboxylate has a lower viscosity, which will improve the kinetic performance of the electrolyte and reduce the lithium precipitation on the negative electrode side of the battery. On the other hand, it is because the carboxylate will have a side reaction at the positive electrode during the float charging process, resulting in certain by-products, so as to achieve the protection of the positive electrode interface and reduce the further reaction between the positive electrode interface and other components in the electrolyte. Compared with the comparative example 1.1, it can be seen that after the amount of carboxylate exceeds 50%, the side reaction between the carboxylate and the surface of the active material is accelerated, which will deteriorate the performance.
- Table 2 shows the effect of the mass percentage content of fluoroethylene carbonate (FEC) in the electrolyte, the type of sultone compound and the mass percentage content in the electrolyte on the performance of lithium ion batteries.
- FEC fluoroethylene carbonate
- Example 1.8 By comparing Example 1.8 with Example 2.1 to Example 2.6, it can be seen that FEC significantly improves the cycle performance of the battery at 45°C. This is mainly because the combination of ethyl propionate, propyl propionate, ethylene carbonate and propylene carbonate with a specific content range and ratio relationship with FEC can achieve a good film-forming effect and reduce the catalytic side reaction between the electrolyte and the active material. , thereby reducing the consumption of electrolyte. From the comparison of Example 1.8 and Example 2.7 to Example 2.13, it can be seen that the addition of sultone can further improve the cycle performance of the battery at 45°C, and also has a certain enhancement effect on the float performance of the battery at 45°C.
- Example 2.14 to Example 2.17 that the combination of FEC and sultone can further improve the cycle performance of the battery.
- Table 3 shows the effects of the types of polynitrile compounds and their mass percentages in the electrolyte on the performance of lithium ion batteries.

- Example 1.8 and Example 3.1 to Example 3.7 From the comparison between Example 1.8 and Example 3.1 to Example 3.7, it can be seen that the float charge performance of the battery at 45° C. is significantly improved after adding dinitrile. From the comparison between Example 1.8 and Example 3.8 to Example 3.15, it can be seen that the float charging performance of the battery is also significantly improved after adding trinitrile. It can be seen from Examples 3.16 to 3.19 that after adding dinitrile and trinitrile, the float charge performance of the battery is further improved. This is mainly because nitriles have electron-rich groups, which can alleviate the catalytic oxidation of the cathode transition metal to the electrolyte to a certain extent.
- nitrile can further improve the cycle performance of the battery on the basis of fluoroethylene carbonate and sultone, which is mainly due to the effective protection of the transition metal at the cathode interface by the nitrile group.

- Each embodiment is a further improvement based on Embodiment 1.8, that is, the difference only lies in the parameters in Table 4.
- Example 4.10 From the comparison of Example 1.8 and Example 4.1 to Example 4.10, it can be seen that the cycle performance of the battery is significantly improved after adding the boron-containing lithium salt. This shows that boron-containing lithium salts have a significant effect on reducing the interfacial side reactions during cycling. It can be seen from Example 4.11 and Example 4.12 that the boron-containing lithium salt can further improve the cycle performance of the battery on the basis of containing FEC, sultone and nitrile.
- Table 5 shows the influence of the types of alkenyl sulfone compounds and the mass percentage content in the electrolyte on the performance of lithium ion batteries.
- Each embodiment is a further improvement based on Embodiment 1.8, that is, the difference only lies in the parameters in Table 5.
- Example 1.8 and Example 5.1 to Example 5.7 From the comparison of Example 1.8 and Example 5.1 to Example 5.7, it can be seen that the float charge performance of the battery is significantly improved after adding sulfone. From Examples 5.9 to 5.12, it can be seen that the vinyl sulfone can also have a better improvement effect when used in combination with other additives.
- Table 6 shows the BET and Dv50 of the cathode active materials and the effect of doping elements on the performance of Li-ion batteries. Among them, in Examples 7.1 to 7.11, based on the total mass of the electrolyte, the content of each component is shown in Table 6 below. Unless otherwise specified, the Al content in the positive electrode active material is 700 ppm, the BET is 0.19 m 2 /g, and the Dv50 is 16 ⁇ m.
- Example 7.1 By comparing Example 7.1 to Example 7.11, it can be seen that the doping of Al and appropriate BET and Dv50 significantly improve the float charge performance of the battery at 45°C.
