Final answer:
The incorrect statement about lithium batteries is that they are non-rechargeable. Lithium-ion batteries used in portable electronic devices, including laptops, are indeed rechargeable and offer several advantages such as high voltage output, low density, and a constant voltage discharge.
Step-by-step explanation:
The statement that is not true in regards to lithium batteries is that they are non-rechargeable. Lithium-ion batteries are indeed rechargeable and are extensively used in many portable electronic devices, including laptop computers.
These batteries are known for their high voltage output, approximately 3.7 V, and their ability to provide a significant amount of current. They are also characterized by their low density, which makes them lighter than other comparable batteries, and they maintain a nearly constant voltage throughout their discharge cycle.
It is important to note that while lithium-ion batteries are rechargeable, there are also primary lithium batteries, such as lithium-iodine batteries, which are non-rechargeable. However, since the question likely refers to lithium-ion batteries used in electronics like laptop computers, the correct answer would be that they are not non-rechargeable.
