Electric car batteries: steady state, Nissan begins production


This technology promises a significant increase in autonomy, a reduction in charge times and a reduction in fire risks to a minimum. The Japanese company intends to equip its cars with these batteries from 2028

Low impact on the environment, cheap and doubly efficient: solid state batteries could represent the key to popularizing electric mobility. Nissan’s development and research activities are ongoing new solid state battery technology which will facilitate their various products, including pick-ups. Production line setup operations have begun in Japan, within the Yokohama factory. The goal is making their electric cars even more efficient and do, take advantage of the good features of this type of technology. The project is also part of a long-term plan Nissan Ambition 2030which aims, by 2028, to be able to supply energy to its vehicles through solid state batteries.

How does it work?

The operation of the battery depends on the electrochemical cell consisting of two electrodes: anode and cathode. The movement of cations (positively charged ions) between the negative pole of the anode and the positive pole of the cathode occurs through the ion conductor: this produces an electric current. In standard batteries lithium ion, the conductor is a liquid compound that has a great loss: it is especially burning. Therefore, through research we have tried to replace the liquid conductor with a solid conductor.

information

Solid-state batteries are a type of battery whose structure is similar to conventional lithium-ion batteries. The difference is in the solid state of the electrolyte, i.e. a conductor, which is usually a liquid. Moreover, in these batteries there is no need for a special isolator that would normally avoid a short circuit or fire. Since the electrolyte itself acts as a separator the risk of explosion or fire is eliminated and the need for security features. Important storage of space makes the battery more efficient; More than that It’s crowded approximately twice that of conventional batteries, allowing faster charging times and greater autonomy, being able to store more cells with the same volume and weight. Furthermore, freedom from materials with a high environmental impact it reduces the cost of production and that of disposal or recycling.
