Application:
Portable Devices:
Laptops and Notebooks: Li-poly batteries contribute to the sleek and lightweight design of modern laptops.
Portable Game Consoles: These devices rely on Li-poly batteries for extended gaming sessions without being tethered to a power outlet.
E-readers: Devices like Kindles use Li-poly batteries to ensure long reading times on a single charge.
Electric Vehicles (EVs) and Drones:
Electric Scooters and Bicycles: Li-poly batteries offer high energy density, making them ideal for powering electric transportation options.
Drones: These unmanned aerial vehicles use Li-poly batteries to support long flight durations and stable performance.
Electric Cars: While lithium-ion batteries (which can include lithium cobalt oxide, lithium nickel manganese cobalt oxide, or lithium iron phosphate chemistries) are more common in full-sized EVs, Li-poly batteries have been explored or used in some hybrid and smaller EV models due to their packaging flexibility.
