As far as batteries are concerned, nothing can improve the performance of a lithium-ion battery (LiIon Rechargeable or Li-Ion Rechargeable for short). They last longer than many other types of batteries and have different uses. Lithium ions are often more expensive than other types, but they are worth more for your battery-powered product.

The important element is that most lithium-ion batteries are obviously rechargeable. While you can get rechargeable alkaline batteries, lithium-ion batteries have more storage capacity to keep your product running on a full charge. Even if you are familiar with lithium batteries, which are recommended by most manufacturers for use in electronic devices, they do not charge. Only the lithium-ion battery is charged.
The main difference between a lithium-ion battery and an alkaline battery (the typical type you buy at the store) is that you can only use the alkaline battery once. They start to work really well and have a pretty long life, but eventually, they will wear out and you will have to buy new ones. Lithium-ion models start with a longer life and have more power for a longer time. When they wear out, all you have to do is recharge them to get more lives out of them.
The reason many people turn to lithium-ion batteries is that they do best in wearable technology. For example, most people use lithium-ion batteries in portable DVD players or other electronic devices because these batteries will hold power longer.
