CATL is looking at the dynamics that san aircraft usually flies at 69-70% power and 100-120% (or time rated 100%) for only a few minutes.. add to that, gears and bearings are inherently power power robbers. Additionally gas turbines can not regenerate energy and are least efficiency at low speeds (taxiing), take-off and climb. In the short haul routes, speed can be reduced, fuel load is not such a big factor. By using more efficient electric motors coupled with super capacitors, high output power can be achieved with minimal weight, and the regenerative mode of the electric engines can recharge the electrical load on decent, power savings can be achieved for essential ad potential maneuvering further enhancing the electrical concept. As for the idea of jet speed and jet range, that will have to be sacrificed and until LiPo batteries can be replaced due to their rather explosive and fire properties, rich people will have to think rather hard at these downsides and the ranges will probably be not as stated, but half to 1/3 of the stated goals without a backup engine installed. It is a proof of concept, best for the company aircraft that is based off the company airstrip, a situation that is quite rare. One other factor is the break-up of the world economic structure that will limit the export of such small aircraft by export taxes and plain out sanctioning to the dominant richer western elite. I'd say that training aircraft would be a better target 'audience' for the local market.

Battery Swapp Technic. Fly Swapp Fly. Charge with Solar Power and Wind Power. Fly Swapp Fly. Go Anywhere.
But still a long way to go to even compete with jet engines. Probably developed for propeller planes only.
Thank you China for your investment in advancing battery technology.
