Definitions
- Lithium-ion batteries are gradually replacing lead-acid batteries, Ni-Cd and MH-Ni batteries due to their higher volumetric specific energy, weight ratio energy and environmental friendliness, and are widely used in portable electronic devices such as mobile phones and notebook computers. Among them, it has a good application prospect. According to the electrolyte used in the lithium ion battery, it can be classified into a liquid lithium ion battery and a polymer lithium ion battery. Liquid lithium ion batteries have good high charge and discharge rates and low temperature performance, but the disadvantages are: liquid electrolyte may leak, which will endanger the safety of the battery; and because the liquid lithium ion battery is packaged as aluminum or steel, the limit The arbitrariness of its shape.
- the mass percentage of the auxiliary salt is 0 to 30%; the main salt of the mixed salt is at least one of the following: LiPF 6 , LiBF 4 , LiC10 4 , Lil, LiN0 3 , LiCF 3 S0 3 , LiN (CF 3 S0 2 2 , LiN(CF 2 CF 3 S0 2 ) 2 , the auxiliary salt of the mixed salt is at least one of the following: LiB (C 2 0 4 ) 2 or LiBF 2 C 2 0 4 .
- the secondary lithium battery is a mixed salt, and the primary lithium battery is a single salt.
- Non-aqueous solvent containing lithium salt 1. 0M LiC104, PC/EMC/DE04: 3: 3, weight ratio: 93.44%. This is a battery, no salt is mixed.
- the first polymerization temperature is 85° (:, the time is 45 ⁇ 60 minutes; the second polymerization temperature is 45° (:, the time is 16 hours, the flowing mixed electrolyte forms a stable condensation) Glue electrolyte.
- the preparation of the mixture and the injection step are all carried out in a glove box under nitrogen protection, and the in-situ thermal polymerization is carried out in a normal oven.
- Methyl methacrylate 0. 8wt %
- the non-aqueous solvent containing the lithium salt Pre-form the non-aqueous solvent containing the lithium salt into two parts, and then add the initiator azobisisobutyronitrile to one part and stir evenly to obtain a gel electrolyte component for the lithium battery; at the same time, various monomers, Add another part of the coupling agent and stir evenly to find the gel electrolyte component ⁇ for the lithium battery. Finally, the gel electrolyte component ⁇ and the gel electrolyte component B are mixed one by one by weight ratio, and the mixed solution is a colorless or light yellow transparent liquid.
- the initial capacity of the gel polymer battery is slightly higher than that of the conventional liquid electrolyte lithium battery.
- the capacity retention rate and capacity recovery rate of the gel polymer battery are slightly lower than that of the conventional liquid electrolyte, but higher than 85%, which meets the battery use requirements.
- the performance of the composite salt gel polymer battery is superior to that of the single salt gel polymer battery, and the use of the composite salt has a large improvement in the electrical properties of the battery. That is to say, the gel polymer electrolyte formed in the experimental example 3 can satisfy the electrochemical performance requirements of the lithium iron phosphate secondary battery, and at the same time ensure that the liquid leakage is improved to improve the safety performance of the battery.
