A LiPo battery or lithium polymer battery or lithium-ion polymer battery is a type of rechargeable battery based on the lithium-ion technology that utilizes polymer electrolyte.
There is no denying lithium batteries are expensive. They are loved by many and have grown in fame because of their high capacity and long life. Today, almost every electronic device, including electric cars, run on these batteries.
The focus of most battery research is now majorly on lithium chemistry. With this level of research, you can imagine the future of batteries is entirely lithium.
Most of the modern devices we use today requires to be powered by lithium-ion batteries, but there are many other devices which functionality is not suitable for energy from these types of batteries.
