On September 18, 2025, Panasonic Holdings Corp. announced it plans to release its first samples of new solid-state batteries by the fiscal year ending March 2027, in a bid to capture the next-generation battery market for robotics and other devices.
Soichiro Watanabe stated the company initially intends to apply its new solid-state batteries in industrial robots, tire pressure monitoring systems, and other applications where their advantages in high-temperature environments can be leveraged.
According to reports, Panasonic also aims to develop a new high-capacity battery within approximately two years. This could represent a breakthrough for the Tesla supplier, potentially significantly extending the driving range of electric vehicles.
Panasonic is working to eliminate the battery anode during the manufacturing process, using innovative technology to enhance energy density. The company claims that this technology is expected to achieve world-leading battery capacity by the end of 2027.
Panasonic stated that if this goal is reached, battery capacity could increase by 25%. Based on current battery pack sizes, the range of Tesla’s best-selling Model Y is projected to increase by nearly 90 miles (approximately 145 kilometers).z
Panasonic Leading the Way to Solid-State Innovations
Alternatively, the technology could allow Panasonic to reduce the size of the battery pack while maintaining the current vehicle range, thereby producing lighter and potentially cheaper battery pack.
On September 18, ahead of a presentation by Shoichiro Watanabe, CTO of the group’s battery division Panasonic Energy, a company executive introduced the anode-free technology. It is reported that several global battery manufacturers are also researching this technology.
Panasonic’s innovative approach completely removes the anode structure during manufacturing. After the initial charge, a lithium metal anode is formed within the battery. This creates more space for active cathode materials such as nickel, cobalt, and aluminum, increasing battery capacity without changing its volume.
Panasonic also stated that it aims to reduce the proportion of nickel in its batteries, as nickel is relatively expensive.
It remains unclear whether this technology will help Tesla reduce prices, and Panasonic has not disclosed details regarding manufacturing costs.
