Description

Technical Field

[0001] The utility model relates to the technical field of start-stop batteries, in particular to a sodium ion starting battery. Background Art

[0002] Sodium-ion batteries are rechargeable batteries that rely primarily on the movement of sodium ions between the positive and negative electrodes, similar to lithium-ion batteries. Sodium salt raw materials are abundant and inexpensive, and using iron-manganese-nickel-based cathode materials reduces the raw material cost by half compared to lithium-ion battery ternary cathode materials. The properties of sodium salts allow the use of low-concentration electrolytes (for the same electrolyte concentration, sodium salt conductivity is approximately 20% higher than lithium electrolyte), reducing costs. Sodium ions do not form alloys with aluminum, so aluminum foil can be used as the current collector for the negative electrode, further reducing costs by approximately 8% and weight by approximately 10%. Because sodium-ion batteries have no overdischarge characteristics, they can be discharged to zero volts. Sodium-ion batteries have an energy density greater than 100Wh / kg, comparable to lithium iron phosphate batteries, but with significant cost advantages, making them promising candidates to replace traditional lead-acid batteries in large-scale energy storage.

[0003] Currently, the car start-stop batteries on the market are generally lead-acid batteries or lithium iron phosphate batteries. Ordinary lithium iron phosphate start-stop batteries do not have an emergency function. Utility Model Content
