A proof-of-concept battery with a range of 1210 kilometres has been demonstrated by a US company.

Our Next Energy, Inc. (ONE), a Michigan-based battery technology company, has demonstrated a proof-of-concept battery that can power an electric vehicle for 752 miles (1210 kilometres) without recharging. According to the business, the vehicle conducted a road test across Michigan in late December with an average speed of 55 mph.
The results were certified by a third party using a car dynamometer, where the test vehicle, a Tesla Model S modified with an experimental battery, accomplished 882 miles (1419 km) at 55 mph, according to a press statement.

The founder and CEO of ONE, Mujeeb Ijaz, stated, “We want to hasten the adoption of electric vehicles by removing the fear of running out of gas, which now holds back the majority of users. We’re now working on turning our proof-of-concept battery into Gemini, a new product that will allow long-distance trips on a single charge while lowering costs and enhancing safety by using sustainable materials.”
Is it going to be a success?

Due to the limited range of today’s electric vehicles, adoption is poor. Even the most powerful electric vehicles on the market today lack the extra power needed to face real-world challenges like high-speed driving, inclement weather, mountainous terrain, or carrying trailers. According to the press release, these variables might result in a loss of over 35% of the rated range, causing annoyance and worry on road trips.

“By doubling the available energy on board in the same package space, the ONE Gemini battery hopes to eliminate range as a barrier to electric car adoption,” Ijaz said.
Until now, the industry’s solution to the range problem has been to add additional charging stations. However, relying on fast-charge stations has other drawbacks, such as long lineups, slow recharging, and being limited to a partial charge, which necessitates stopping every 150 miles (240 km), according to the business.
