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 (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...

what angle should solar panels be mounted? Oct 11, 2022

1. The optimal placement angle of solar photovoltaic panels is 45 degrees. 2. When installing solar panels, the first thing to consider is the choice of direction. If you choose the wrong direction, the angle is useless. If the direction is wrong, it will not receive sunlight at all. Now common solar devices, such as solar street lights, have been carefully observed and found to be in the south di...
