lithium-ion batteries
Rechargeable portable energy storage
Lithium-ion batteries are rechargeable power cells that use lithium compounds to store and release electrical energy.
They dominate portable electronics—phones, laptops, electric vehicles—because they pack more energy into less weight than older battery types.
My phone's lithium-ion battery needs replacing.
The technology requires careful management to prevent overheating.
