Another new type of fast-charging battery
I believe that there has never been as much research done on electric batteries as there is today, and the reason is very simple: the huge market for electric devices. They are needed in cars, robots, and other types of vehicles, and also in the many devices that we all carry with us.
Most of the efforts are directed to obtain batteries with a higher charge capacity (and if possible with a shorter recharge time) so that electrical devices work for a longer time. That way the cars will have greater autonomy, etc …. , and there are already some prototypes working and it is expected that they can be on the market in a few years.
But on the other hand, others put the priority on achieving very short recharging times, even though the capacity of these batteries is similar to the current ones. Their strategy is very clear: if a battery recharges in just over 2 minutes, we won’t mind recharging it while having a coffee.
The latter is the case of the Tyfast company, which promises rechargeable batteries in 3 minutes with up to 20,000 recharge cycles. And it is a proposal to be taken very seriously.
Their batteries are made up of an anode with vanadium, instead of the graphite used in today’s batteries. This means that the ions can be moved much more easily, improving the speed of recharging and the number of recharges that it supports during its useful life.
The anode material is somewhat more expensive, but the battery supports more than twice the number of recharges, so that throughout its useful life it can be economically viable.
If one thinks of a current electric car that has a range of between 300 and 400 km, and that can be fully recharged in about 3 minutes, this option can be very feasible, since refueling takes a similar time.
And the same can happen with other devices such as robots. If it can be recharged in 3 minutes, that means the robot can be operational almost 24 hours a day.
The business approach of these people can have good prospects. Now it is necessary to confirm that the “promises” they make of their batteries materialize.
Time will tell.
