Customer ServiceA car battery is more prone to sulfation when the motor is usually idle or driven at low speeds. In these conditions, the battery is not charged sufficiently and that causes sulfation. A good way to determine if your battery has a sulfation problem is when it is not accepting a charge the way it is supposed to. With that, you need to determine

Customer ServiceIn contrast to the conventional understanding, lithium crystallization takes multi-step pathways mediated by interfacial lithium atoms with disordered and random-closed-packed configurations as intermediate steps, which give rise to the energy barrier of crystallization.
In Li-ion batteries, lithium ions move from the anode through an electrolyte to the cathode during discharge, and back during charge . The cathode material is made of a powdered intercalated lithium compound.
Capacity is irreversibly lost due to otherwise cyclable lithium being trapped within the SEI.33 In addition, the SEI layer is less permeable to Li+ ions than the electrolyte, restricts electrolyte flow through pore blocking and consumes the electrolyte solvent. All of these effects increase the overall impedance of cells, leading to power fade.
The atomistic understanding about the lithium crystallization at the solid interfaces has been obtained recently via LAMMPS MD simulation . A multistep crystallization atomistic pathway (Figure 2) was proposed based on the MD results, which is different from the conventional understanding.
