How to improve the energy density of lithium batteries? Aug 04, 2022

Energy density refers to the amount of energy stored in a certain unit of space or mass of matter. The energy density of a battery is the electrical energy released by the average unit volume or mass of the battery. The energy density of a battery is generally divided into two dimensions: gravimetric energy density and volumetric energy density. What is energy density? Energy density refers to the...

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...
