三元鋰電池與磷酸鋰鐵電池的差異
At Present, Lithium Batteries Are Mainly Used In Power Batteries. According To The Positive Electrode Material Of The Battery, It Can Be Divided Into Two Categories: Ternary Lithium Battery And Lithium Iron Phosphate Battery.
The Characteristics Of Ternary Lithium Battery
Ternary Lithium Refers To The Compound Of Three Elements And Lithium. The Addition Of Three Elements Can Adjust The Characteristics Of Lithium Batteries, And The Performance Of Batteries Produced By Adding Different Ratios Is Also Different. The Three Elements Are: Nickel Cobalt Manganese Or Nickel Cobalt Aluminum.
523, 622, And 811 Batteries Add Three Elements According To These Numbers. Simply Put, The Larger The First Number, The Higher The Energy Of The Battery, But At The Same Time The Higher The Cost And Risk.
Characteristics Of Lithium Iron Phosphate Battery
Lithium Iron Phosphate Battery Is A Lithium Ion Battery That Uses Lithium Iron Phosphate As The Positive Electrode Material And Carbon As The Negative Electrode Material.
Advantages Of Lithium Iron Phosphate Battery
1. Good Safety, Not Easy To Spontaneous Combustion.
2. Long Service Life, About 3000 Cycles.
3. The Material Cost Is Low.
Disadvantages Of Lithium Iron Acid Battery
1. The Energy Density Is Low, And The Battery Life Of The Vehicle Is Not High Enough.
2. Poor Low Temperature Resistance, Battery Life Is Significantly Reduced In Cold Winter.
Comparative Analysis Of Two Lithium Batteries
Generally Speaking, The Two Types Of Batteries Have Their Own Strengths And Weaknesses, And They Meet The Needs Of Different Scenarios. The Main Difference Lies In Battery Life And Price. Ternary Lithium Has Long Battery Life, High Price And High Risk, While Lithium Iron Phosphate Has Short Battery Life, Cheap And Safe.
At This Stage, The Safety Of The Battery Has Been Well Controlled, And The Phenomenon Of Spontaneous Combustion Has Been Greatly Reduced. More Importantly, There Have Been No Casualties Caused By The Spontaneous Combustion Of The Battery. The National Standard Requires That After The Battery Heats Out Of Control, There Will Be No Fire Or Explosion Within 5 Minutes. Some Manufacturers Claim That It Can Be Extended To 30 Minutes To Ensure The Safety Of Personnel. Therefore, In Normal Use, There Is No Need To Worry Too Much About Battery Safety.
Purchase Suggestion:
At Present, Some Brands Will Equip The Same Model With Two Different Batteries For Users To Choose. Under Other Conditions Being The Same, Regional Climate Factors Can Be Considered Comprehensively. Ternary Lithium Battery Models Are Given Priority In Northern Alpine Regions To Avoid Battery Performance Degradation In Winter; Lithium Iron Phosphate Battery Models Are Given Priority In Southern High Temperature Regions To Reduce The Risk Of Spontaneous Combustion In Summer; The Central Region Is Optional.
Exploration Of More New Materials
1. Ternary Iron-lithium Battery Pack
The Ternary Iron-lithium Battery Pack Recently Launched By Weilai Automobile Is Composed Of Two Kinds Of Battery Cell Modules, Which Maximizes Strengths And Avoids Weaknesses, And Reduces Battery Costs While Increasing Power.
2. Sodium Ion Battery
The Sodium-ion Battery Recently Released By The Ningde Era Can Almost Perfectly Solve The Common Problems Of Current Lithium Batteries. The Only Problem Is That The Energy Density Is Slightly Low, And It Has Good Prospects For Application In Low-end Electric Vehicles And Electric Energy Storage. There Is No Specific Timetable For Mass Production Of Sodium-ion Batteries, Let Us Wait And See.
