The new IBM battery is to be more efficient and environmentally friendly than lithium-ion


Good news for the world of electronics.

Smartphones, laptops, tablets, drones and even electric vehicles – all these devices are usually powered by lithium-ion batteries. Of course, we use many of these devices every day, so now it is difficult for us to imagine life without these batteries. It is no wonder then that the people who contributed to their creation were awarded this year Nobel prize in chemistry.

However, lithium-ion batteries are not ideal. These can unseal, explode and burn, and are prone to aging. In addition, heavy metals such as cobalt are needed for their production, the extraction of which not only contributes to environmental pollution, but also involves many irregularities in terms of legal employment. Alphabet, Apple, Dell, Microsoft and Tesla, which use cobalt mined in the Democratic Republic of Congo, have just been sued on behalf of several Congolese families by International Rights Advocates leading to the death or disability of children forced to work in mines.

The solution to these problems may be a new battery that IBM has just boasted. Compared to a lithium-ion battery, it is expected to have lower production costs, faster charging time (up to 80% even in 5 minutes), higher power density (over 10,000 W / L) and energy (over 800 Wh / L), higher energy efficiency as well as lower flammability. This means that thanks to it electronic devices can become cheaper and safer to use, and in addition there is a chance that we will be able to enjoy them longer without having to connect them to the charger.

The IBM battery is also to be more environmentally friendly, because it does not use nickel or cobalt, and materials obtained from sea water. There are three materials in particular, but so far IBM has not disclosed what materials they are. The battery also supposedly contains a new type of liquid electrolyte.

As reported by IBM, the first laboratory battery tests have resulted very promising results. Due to the absence of nickel and cobalt, so-called dendrites are not formed inside it, i.e. protrusions that in lithium-ion batteries promote short circuits, increasing the risk of ignition.

In order to further refine its technology and, in time, also introduce it to the market, IBM began cooperation with companies such as Mercedes-Benz Research and Development. I hope that we will see the battery sooner or later and that it will offer the parameters that IBM declares. After all, in the last few years you could hear about many amazing breakthroughs in the work on new types of batteries, but nevertheless no new types of batteries, better than lithium-ion batteries, have not yet seen the light of day.
