Lithium-ion batteries have high energy density and are among the strongest batteries. They have a low self-discharge rate compared to NiMH batteries and are not subject to memory effect. They do not require regular discharging, thus requiring little maintenance. With proper storage, these rechargeable batteries are long-lasting, durable, and have many possible charging cycles. Li-ion batteries are used in various high-energy portable devices such as smartphones, notebook computers, cameras, and electric power tools. These batteries can also be used in radio-controlled models and telecommunications applications.
