The future of the electric car: lithium-free and structural batteries for the car
In 2019, nanotechnology company Nanom built a boat. Not a normal boat, the Magnea (as it was called) was built with a hull that was a "carbon fiber structural battery". In simple terms, they built a cell with a capacity of 500 kWh directly into the structure of the boat. For comparison, the Tesla Model S has a battery capacity of 100 kWh. The company says its nanotechnology that makes this possible could also reduce the price and weight and increase the efficiency of the lithium-ion batteries that currently power electric vehicles.
Currently, the largest expense of an electric vehicle is the battery, which also costs 200 dollars per Kw / h and which also constitutes the greater weight of the car. What if these problems could be solved in one fell swoop?
This is where Nanom believes it can help . The company says that creating nanoparticles of some of the chemicals used in batteries can not only make them more efficient, but can also increase the flow of electricity and reduce long-term capacity degradation of batteries. The energy density, life span and recharge rate of these batteries are expected to increase more than nine times what is currently available on the market. Very interesting is the number of recharge cycles that the battery can withstand: we are talking about 50 thousand cycles! We talk about 137 years of daily refills !!
The Nanom battery design uses the same technology as Thomas Edison's patented nickel iron battery in 1901. These batteries were and are known for their ability to last for years, even decades. Nanom just removed the heavy iron and nickel plates and replaced them with iron and nickel nanoparticles .
Around these micro-particles the company creates a carbon fiber weave that integrates a cathode and an anode and uses a silk or glass fiber electrolyte separator. In this form, the whole battery becomes a structurally usable element. The battery will not release electric shocks, and in the chaos of accident or damage it will continue to produce electricity from connections that remain intact. With this battery it will be much easier to build cars that structurally include batteries, but electric planes and boats will also become feasible. The future is around the corner.
