USA, 16 September 2022: A Harvard-backed startup, Adden Energy, has developed a battery that can be fully charged in 3 minutes and last twice as long as current electric vehicle batteries. If these batteries are scaled up successfully, they can revolutionize electric vehicles in the future.
More money is being invested in battery technology as interest in EVs increases. A sizeable amount of the money is going into developments that can help EVs get over their current battery-related problems.
Here are just a few of the cutting-edge battery technologies that could influence how EVs develop in the future:
The lithium-ion (Li-ion) cathode and graphite anode battery systems make up almost all of the batteries in use today, from electric vehicles (EVs) to smartphones. Although many battery system substitutes are being investigated, most of them are less energy dense. However, fluoride cell batteries not only have a roughly 10-fold greater energy density than Li-ion cells, but they are also less expensive.
Salt is the sixth most common substance on Earth, and sodium is one of the most prevalent chemicals. Na-ion batteries could thus be far less expensive than current batteries. As a by-product of desalination, which creates potable water from seawater, sodium can also be extracted. They are a promising alternative since they may charge considerably more quickly than current batteries and have a longer lifespan.
Organosilicon electrolyte batteries
Stop-gap improvements can help enhance and stabilise the batteries we currently use, even when a more ideal battery composition may not be available for several decades. Li-ion batteries are more stable and less likely to have thermal runaway when organosilicon electrolyte solutions are used as electrolytes, according to research. This lowers the risk of fires.
Structural battery architectures
The battery packages in today’s EVs account for a considerable amount of their weight and price. In order to begin integrating EV batteries as a structural component of the car, researchers have been searching for a solution. Structural battery topologies can drastically lower the price and weight of automobiles because the batteries already have the strength to support the construction of the car, which can further improve efficiency in terms of range and lifecycles.
Solid-state battery architectures
The liquid electrolyte used by modern Li-ion batteries facilitates the transfer of charged particles between the anode and cathode. However, switching to solid-state electrolytes can offer a variety of advantages, including making batteries non-flammable, more energy dense, with higher range, longer lifecycles, faster recharging, and better ability to withstand high temperatures.
