Evolved Batteries
Lithium is highly reactive because it readily loses its outermost electron, making it easy to get current flowing through a battery. Lithium is much lighter than other metals used in batteries, such as lead, which is important for small objects such as phones but also for cars that require many batteries.
Lithium-ion batteries are rechargeable, because lithium ions and electrons move easily back into negative electrodes. This battery cells are lightweight compared to other battery technology. Check Disclaimer On Profile.
