Lviv-based company PAWELL Battery has held a series of negotiations with Japanese battery manufacturers and plans to receive the first test batches of new power cells in 2027. The company hopes that they will help Ukrainian drones fly longer, work better in cold weather, and be less dependent on Chinese components.
Lviv-based company PAWELL Battery has held a series of negotiations with Japanese battery manufacturers and plans to receive the first test batches of new power cells in 2027. The company hopes that they will help Ukrainian drones fly longer, work better in cold weather, and be less dependent on Chinese components.
This was reported by the press service of PAWELL Battery.
Japanese developers are working on batteries that can maintain their performance even at temperatures as low as -30 degrees Celsius. This is especially important for drones, because in the cold, conventional lithium-ion batteries lose their charge faster, which means their flight time is shortened.
Another benefit the company hopes to see is safety. Solid-state batteries could be more resistant to damage and less prone to ignition. And with higher energy density, drones could potentially stay in the air longer without adding to the battery's weight.
Now PAWELL Battery plans to move from negotiations to testing. The first batches of Japanese cells are expected to be delivered to Ukraine in the first half of 2027. First, they will be tested in laboratories, and then tested on drones together with the military and UAV manufacturers.
If everything works out, the new batteries could be used in both drones and electronic warfare systems. The company also wants to establish direct supplies of Japanese batteries to other Ukrainian manufacturers so that they are less dependent on Chinese components.
Earlier, dev.ua wrote that Lviv engineers gained access to batteries with an ultra-high energy density of 550 Wh/kg. According to the developers, such batteries can increase the flight time of Ukrainian drones by about 30% without additional weight.
