The new white gold or the oil of the future is what many call lithium today due to its great utility and importance for the electronics industry, the electric industry, and the transition to renewable and clean energies. Lithium is a metal that is mainly used for the manufacture of rechargeable electric batteries. These batteries, called lithium-ion batteries, are used to store electrical energy and are found in many of the electronic devices we use: our laptops, smartphones, tablets, cameras, etc. They are also found in electric vehicles and health care devices.

Retrieved November 19, 2022, from https://www.todoaccesoriosmoviles.com/baterias-samsung-s4/ Pros of lithium-ion batteries High energy density: These batteries have the potential to accumulate much more charge per unit volume compared to Ni-Cd or Lead-Acid batteries. This is because lithium is a very reactive element, which means that it can store a lot of energy in its atomic bonds. They are light: A one-kilogram lithium-ion battery can store the same amount of energy as a six-kilogram lead-acid battery. This characteristic makes lithium-ion batteries very useful for portable devices. Maintain their charge for extended periods of time: Compared to NiMH batteries, which lose 20% of their charge each month, lithium-ion batteries only lose roughly 5% of their charge each month. No memory effect: The memory effect is the reduction of the capacity of batteries with incomplete charges. Lithium-ion batteries do not have this problem, which allows us to recharge them without having completely discharged them. Linear discharge: While the battery is discharged, its voltage almost does not vary; therefore, it does not require regulating circuits. Low percentage of self-discharge: A battery always discharges progressively, in spite of not being used. In the case of lithium-ion batteries, the self-discharge percentage is 6% per month, unlike Ni-MH and Ni-Cd batteries, whose self-discharge percentage is 20% per month. They are less harmful to the environment: Lithium-ion batteries do not contain overly polluting metals such as cadmium, lead, arsenic, and nickel. They have great potential to help us in our transition to renewable and clean energy: Lithium-ion batteries can store significant amounts of energy from renewable sources, such as solar and wind power. According to the Royal Swedish Academy of Sciences, lithium-ion batteries are an element that would contribute to achieving a "fossil-free society." Cons of lithium-ion batteries They are expensive: Lithium-ion batteries are more expensive than Ni-Cd and Ni-MH batteries. They could detonate or catch fire: Some cases have been reported in which these batteries have caught fire and exploded, although this usually happens in devices that have manufacturing defects. This is because they are made of flammable materials, which makes them prone to overheat and detonate or catch fire. They support a limited number of charges: Compared to Ni-Cd batteries, lithium ion batteries support a lower number of charges, between 300 and 1000 charges. Poor low-temperature performance: They have the worst low-temperature performance compared to other batteries (Ni-Cd and Ni-MH). Their life can be reduced by up to 25% in these conditions. In the case of electric cars, recharging their lithium-ion batteries takes a long time (hours) compared to cars using fossil fuels (minutes). Despite their disadvantages, lithium-ion batteries are currently the best option, as they offer more benefits than the others. And they have a key characteristic that is very important for the times we are living in: they have less impact on the environment. Nevertheless, batteries that will surpass lithium batteries in all aspects are already being developed: aluminum ion, graphene, and silicon batteries. Although still in the research and testing stage, these batteries appear to be the batteries of the future. Reference materials: Mártil, I. (2019, March 20). Baterías de Ion-Litio: Pros y Contras.

Hi, Anghy Aquino!
This is your mentor, Yoon.
Thank you for introducing the ups and downs of LIBs. As you mentioned, LIBs are mainly studied due to their high energy density resulting in lightweight batteries.
Since we moved from Ni-Cd or Lead-Acid batteries to LIBs, I am sure that we will be moving on to next-generation batteries, such as silicon anode LIBs, ultra-thin lithium metal batteries, etc., soon.
Great job on writing the thematic report.
I am looking forward to reading your following report!

Hello, this is your mentor Minkyung.
Thank you for describing the pros and cons of Li-ion batteries. Because you highlighted the main points, I could easily understand the content of your report. I hope you gained much knowledge and insight about Li-ion batteries while writing this report!
I'll be looking forward to your next report :)
