Lithium-ion batteries are used everywhere, from lighting our mobile devices to powering the electric cars we drive. Lithium-ion batteries are the best batteries we have today. These batteries will be the best batteries we will have for a long time because of their efficiency. These batteries come in many shapes and sizes, so they can be used in a variety of devices. Lithium-ion batteries are the most efficient batteries and their benefits far outweigh any safety concerns. Say no to plagiarism.

Get the original essay Lithium-ion batteries are everywhere today in our phones, hand-held power drills, computers, and more. We have “reached about 90% of the total capacity of these batteries” (The Verge). These batteries also have many protections, for example a thermal fuse to prevent thermal runaway from occurring, a chip to cut off the power when it becomes low and when fully charged, making it "almost the best battery”. there is” (The Economist). Additionally, these batteries are relatively new, so companies don't have many restrictions on what these batteries should include. Unfortunately, a Chinese company can sell them very cheaply and they could be built in a very dangerous way. To help understand this debate over the value of using lithium-ion batteries, one must also understand the history. Lithium-ion batteries were first used commercially "in the 1980s, but failed due to instabilities of metallic lithium used as an anode material" (Battery University). In 2000, Sony released these batteries for its products and they were much safer than the previous versions of these batteries. Additionally, “the purer the electrolyte, the more efficient the discharge and charge can be” (BASF) and the less chance there is of an internal short circuit in the battery that could cause a fire. Along with the power of these batteries, safety measures such as overload protection have been put in place to keep them stable. All of these elements together create a safer, more efficient battery for everyone. One of the reasons people like lithium-ion batteries is that, for their lifespan, they “only lose 5% of their lifespan in a month” (Battery University). Another reason why people like these batteries is their different sizes, for example the size of an AA cell or a single flat cell of your phone. Finally, these batteries require little maintenance to keep them running. Excerpted from “The energy density of lithium-ion is typically twice that of standard nickel-cadmium” (Battery University). All these reasons confirm that lithium-ion batteries are convenient to use and are used in our daily lives. A final reason why people like these batteries is the different sizes available. These batteries allow companies to make car battery jumpers that can start your car and fit in your pocket. Also “manufacturers are constantly improving lithium-ion” (Battery University). Along with the constant improvement of these batteries, they are getting better and better. Lithium-ion batteries are “almost the ideal batteries” (The Economist). On the other side of this debate are opponents of lithium-ion batteries. These batteries need to be maintained for them to last. " If)..
