Explained Simply #14: how does a battery store electricity?
It stores chemical energy: charging pushes lithium ions to one side; using it lets them flow back while electrons run through your device.
Your battery doesn't actually store electricity. Wait, what? 🔋🤯
🥪 Inside a lithium-ion battery: two layers (graphite + metal oxide) with a thin wall between them.
🔌 Charging pushes tiny lithium ions through the wall into one side.
⛰️ Like water pumped uphill — the energy is stored in chemistry.
📱 So what runs your phone? Electrons! They take the outside path, through the wire and your phone…
↩️ …while the ions slide back inside. Charge it again and you push them back.
