Sri Lanka, Sept. 21 -- The Japanese company is working on eliminating the anode in batteries during the manufacturing stage to increase energy density through technology it says is likely to provide a "world-leading level" of capacity by the end of 2027.

If achieved, the improvement could increase the driving range of Tesla's most affordable sport-utility vehicle, the Model Y, by almost 90 miles (about 145km), at current battery pack size, Panasonic says.

Alternatively, Panasonic could also use the technology to make lighter - and potentially cheaper - versions of batteries by keeping the current driving range and shrinking the battery pack size.

A company executive told reporters of the anode-free technology ahead of a presentation on ...
