As a result of the reduced size and increased power appetite of modern laptops and other portable devices, the industry had to invent lithium-ion (Li-ion) rechargeable batteries. The use of light carbon and lithium for electrodes makes these batteries particularly lightweight and compact. In addition, performance is better than traditional rechargeable batteries.
As a power source for many applications, lithium-ion batteries have evolved into a market leader since the 1990s. The explosion of the electronic consumer market has led to the impressive popularity of these batteries, which are now used in iPods, iPhones, MP3 players, PDAs, laptops, and other electronic devices. You can also buy Li-ion batteries for electric cars through online sources.
Energy density is the factor that determines the weight and size of the battery. With its dramatically improved energy density, Li-ion batteries allow designers to create slimmer and lighter gadgets for today's market. There are also applications in industries such as aerospace, automotive, and defense where high energy density of Li-ion batteries is required.
Since they have a high operating voltage, only fewer cells need to be combined into one pack, which reduces assembly costs and improves reliability.
Lithium-ion batteries also have no memory effect, so it is not necessary to fully discharge them before being recharged. Since they can carry many hundreds of discharge and charge cycles, stay in good condition for a long time.
Also, Li-ion batteries can be easily made in various shapes and sizes and hence can be used in various devices.
Without a doubt, lithium-ion batteries are the most powerful and energetic battery available and should be used wherever possible.
