1. Batteries and magnets can be placed together without affecting each other.
Lithium batteries and magnets can be placed side-by-side without affecting each other. This is because batteries convert chemical energy into electrical energy; their metal casing contains an acid solution and a carbon rod, where a chemical reaction occurs. Magnets, on the other hand, are typically alloys containing iron, cobalt, and nickel. Their atoms are arranged in a directional pattern, with all small magnetic moments pointing in the same direction, resulting in a relatively pronounced magnetic property.
Magnetic charging typically involves numerous strong-coupled inductive charges within a confined space. This magnetic coupling process generates significant heat, and high temperatures are fatal to lithium batteries. Therefore, magnetic charging is essentially the same as wireless charging, but the large amount of heat released over short distances and prolonged exposure to high temperatures can damage the battery.
In short, magnets will not damage the battery, but a lot of heat is dissipated during the magnetic resonance coupling process, and prolonged exposure to high temperatures will damage the battery.
2. If the battery has an external circuit, there may be a weak interaction because the external magnetic field and the magnetic field generated by the circuit may interact slightly. However, this effect is basically negligible.
3. Regarding whether magnets can magnetize lithium batteries, experts believe that ordinary magnets do not generate a magnetic field for lithium batteries and therefore will not affect them. Even if a magnetic field exists, its impact on lithium batteries is very small and will not affect their lifespan.
