Lithium-ion battery pulping process (1) Aug 30, 2022

Lithium-ion battery pulping process (1) - pulp dispersion and stabilization mechanism According to the different states of matter, the phase states of matter can usually be divided into solid, liquid and gaseous states. In addition, there is another special state of matter between solid and liquid states. Nobel Prize winner Pierre-Gilles de Gennes Such substances are called 'soft substances'. Soft...

Lithium-ion battery pulping process (2) Sep 01, 2022

Lithium-ion battery pulping process (2) - pulp dispersion and stabilization mechanism 3.1 Van der Waals forces According to the London theory, when the wave electrons are distributed around an atom or molecule, a temporary dipole is generated. This temporary dipole causes the adjacent atoms or molecules to generate dipoles, and causes van der Waals attraction between two neutral atoms or molecules...

Which two battery concepts are lithium-ion batteries easily confused with? Sep 20, 2022

A lithium-ion battery is a rechargeable battery that works by moving lithium ions between a positive and negative electrode. Traditionally, the process of lithium ions entering the cathode material is called intercalation, and the process of lithium ions leaving the cathode material is called de-intercalation; the process of lithium ions entering the cathode material is called intercalation, and t...

What are the eight advantages of polymer lithium-ion batteries? Sep 22, 2022

1. Good safety performance The structure of the polymer lithium-ion battery is an aluminum-plastic flexible package, which is different from the liquid battery with a metal shell. Once a safety hazard occurs, the liquid battery is easy to explode, while the polymer battery can only be inflated. 2. Light weight The polymer battery is 40% lighter than the steel case lithium-ion battery of the same c...
