Solid State Batteries “Could” last a Lifetime
Christopher Files / 4 years ago
Among the many annoyances of a tech lovers life which includes, overheating, constant patching, hacking and dropped connections, there is the term battery or lack of considering your average smartphone is dead by the end of each day. Don’t get me started on your run of the mill double A battery, it was fine for a Gameboy, until you had to unreel a long wire with a plug on the end to continue playing, but not for today’s hi-tech toys.
Hopefully, an evolution is on the horizon after researchers at MIT and Samsung have developed a new approach to one of the three basic components of batteries, which in this case is the electrolyte. The premise involves developing a solid electrolyte instead of the current liquid used in today’s most common rechargeables. Current batteries use a liquid organic solvent whose function is to transport charged particles from one of a battery’s two electrodes to the other during charging and discharging, this process has been responsible for the overheating and fires which have caused high-profile disruption.
Another advantage of a solid state electrolyte is the ability to limit degradation to near 0; therefore such batteries could last for “hundreds of thousands of cycles.” Researchers also state these batteries provide a 20 to 30 percent improvement in power density. This means the amount of power that can be stored in a given amount of space can be increased.
By reducing these factors, researchers are hopeful this technique will improve efficiency and waste of the common battery, which in turn will benefit consumers. On a side note, it will be interesting to note how you would put this into practice with the aim of analysing if these batteries would really last for hundreds of thousands of cycles. Indefinite lifetimes in theory, let’s see what a Galaxy S6 makes of that.
Thank you MIT for providing us with this information
