What is the difference between colloidal battery and lithium battery?
Chemical composition:
Colloidal battery: Colloidal batteryThe use of gelling agent in the electrolyte makes the originally liquid sulfuric acid into a colloidal state. This colloidal electrolyte has a lower internal resistance and self-discharge rate, so it can provide better storage performance.
Lithium battery: Lithium battery is a kind of battery with lithium ion as the main medium. They typically consist of lithium metal oxides (such as lithium lithium cobaltate) as the positive electrode material, carbon materials (such as graphite) as the negative electrode material, and use lithium salts in organic solvents as the electrolyte.
Energy density:
Lithium batteries: Lithium batteries have a higher energy density, which can provide higher energy storage and release capabilities. Due to the relatively high energy density of lithium batteries, they are very popular in mobile devices and new energy vehicle applications
Colloidal batteries: Colloidal batteries have a low energy density and are relatively heavy and bulky. Colloidal batteries are more widely used in low-power and long-term applications, such as solar energy systems, wind-solar complementary systems, home energy storage systems, or as a backup power source
Charging performance:
Lithium battery: Lithium battery has good charging performance, can achieve high-speed charging, and can maintain a low self-discharge rate during the charging process.
Colloidal batteries: The charging speed of colloidal batteries is slow, and it takes a longer time to fully charge. In addition, they have a relatively high self-discharge rate and require regular maintenance and charging to maintain performance.
Life and maintenance:
Lithium batteries: Lithium batteries usually have a long life and number of cycles, and do not require regular maintenance. However, overcharging or overdischarging will affect the life of the battery itself
Colloidal batteries: Colloidal batteries can have a long life under correct use and maintenance. However, they require regular charging and maintenance to prevent the buildup of sulfuric acid crystals and evaporation of electrolytes.
