While still a few years away from being commercially available, they promise better life performances, 15 minute charge times, and lower costs They aim to have electric vehicles driving with these cells by 2024! 2. But even though it sounds great in theory, finding a solid material that doesn’t easily crack while still allowing lithium ions to move through it is not an easy task.įounded in 2011, a company called QuantumScape claims to have developed an excellent ceramic material to act as a solid electrolyte. Many companies are investing large sums of money into this technology – Toyota, Volkswagen, and Samsung, to name a few. It also may be capable of recharging much faster and performing more cycles. Using a solid electrolyte, the battery becomes much more compact, leading to a higher energy density. This slight difference makes it much safer by eliminating the risk of contact between the electrodes, overheating and combustion are no longer a concern.īut that’s not all. This technology uses a solid electrolyte, instead of the liquid/gel found in traditional Lithium batteries. Here is a simplified scheme of a Lithium-Ion Battery:Īlthough it still contains lithium, the key difference is the physical state of its components. Each cell comprises four main parts: an anode (-), a cathode (+), an electrolyte, and a membrane separator. Several individual electrochemical cells – where oxidation and reduction reactions occur – compose a Li-ion cell. In order for you to better understand these alternatives – the science behind them and what they promise – let’s first take a quick look at how a Lithium battery works. To solve this issue, many companies are currently investing a lot of time and money into developing new technologies that could potentially replace the popular Li-ion batteries for good in the near future. Not cost-effective for grid integration.The ability to hold charge fades over time. It contains hazardous materials, making proper disposal difficult.High energy density, when compared to other existing batteries.Wide range of applications for small, portable devices.Here are some of the pros and cons of Lithium batteries: Pros: And for decades, “good enough” has been a great way to describe Lithium batteries (pun intended), but not anymore.Īlthough they present significant advantages compared to other already existing types of batteries – such as lead-acid or Nickel-Cadmium – there’s still plenty of room for improvement, especially regarding safety. Released in 1991, the first commercial Lithium-Ion battery (also called Li-ion) was developed by Sony, based on earlier research by John Goodenough. A Lithium battery is a type of rechargeable battery frequently used to power a wide range of devices, from laptops and smartphones to medical equipment and electric vehicles.Īs the name suggests, Lithium batteries are based on the flow of Lithium ions that move “back and forth” between two electrodes, which are crucial components of the battery.
