Nawa technologies, a French company, said it had developed a new electrode design that could fundamentally improve the chemical performance of existing and future batteries. Previously, the company has been known in the supercapacitor market. But now, the same technology is being applied to lithium-ion batteries. In addition to three times the energy density and 10 times the performance, it also has faster charging speed, up to five times the battery life, and quite good cost-effectiveness. The focus of the study is on the retention of active substances in the electrode and the route of ion transfer charge. Taking the current typical activated carbon electrode as an example, it is mainly composed of powder, additives and adhesives. < / P > < p > in the case of carbon nanotubes, they are usually adhered to them in the form of “tangled pasta”, providing a random, chaotic, and often blocked path for current carrying ions (flowing to the collector under load). < / P > < p > on the other hand, Nawa’s vertically aligned carbon nanotubes scheme can create a comb like cathode or anode structure, which can grow hundreds of billions of straight high conductivity nanotubes per square centimeter. < / P > < p > these carbon nanotubes, which are firmly fixed to the tiny electrodes, can then be coated with active substances (lithium ion or other), thus greatly reducing the distance that charges need to travel into or out of the battery. < / P > < p > because each lithium spot is more or less attached to the nanotube which plays a direct road (or part of the collector), the average free travel of ions can be greatly reduced. Pascal Boulanger, founder and chief executive officer of the company, said that with the new scheme, lithium ions could move only a few nanometers across the material, rather than a few microns of a conventional electrode. As a result, Nawa technologies can fundamentally improve the power density of new lithium-ion batteries. Even smaller batteries can achieve 10 times the charge discharge performance of the past. With the right charging infrastructure, it can recharge from 0% to 80% in 5 minutes. < / P > < p > thanks to the ultra light nano scaffold and less binder / additive voids, the battery body can also be more lightweight and compact (2-3 times volume and weight improvement). In addition, the rigid nanotube array and the wide surface area can greatly alleviate the performance degradation (5 times lifetime) caused by time. < / P > < p > finally, Pascal Boulanger said that through cooperation with lithium battery companies, the company plans to make products with some new technologies available in the market from 2022 to 2023.
