Panasonic expects to achieve a 20% boost in energy density for EV batteries by 2030, the company’s CTO said in an interview with Reuters<\/em><\/a> published Wednesday. The interview preceded the company’s announcement to build the largest battery plant in the world<\/a>\u00a0in Kansas City.<\/p>\n

Increasing energy density\u2014essentially increasing the amount of energy stored in a given volume\u2014is a priority for battery makers. It would allow for increased EV range without physically increasing the size of the battery pack, or allow automakers to install smaller packs without a range penalty.<\/p>\n

Panasonic plans to achieve its energy-density boost with a new mix of additives that would allow individual battery cells within a pack to run at higher voltage without ill effects, Panasonic’s Shoichiro Watanabe said in the interview.<\/p>\n

Watanabe said Panasonic planned to reach its goal “over several years,” but did not say when it would begin manufacturing battery cells with the new additives. If achieved, a 20% gain in energy density would likely translate to 900 watt-hours per liter (wh\/l), compared to 750 wh\/l for Panasonic’s most advanced current cell, according to Reuters<\/em>.<\/p>\n

Panasonic is Tesla’s main battery supplier. It already announced in 2020<\/a>\u00a0that it saw a 20% boost in energy density for Tesla-bound cells happening within five years. When gauging the plausibility of these claims, it’s important to remember that energy density improvements tend to come incrementally<\/a>, not in huge leaps.<\/p>\n

Tesla has placed its bets on large-format 4680 cells, which Panasonic plans to start producing<\/a> as soon as spring 2023. Tesla has reportedly been pushing for faster development<\/a> of the new cells, which Panasonic executives don’t seem as confident about.<\/p>\n

Panasonic has said that it does see larger cells as a key to affordable EVs, but it’s been skeptical<\/a> about the 4680 format itself. That said, will it build them at its upcoming U.S. plant? Neither company has confirmed quite yet.<\/p>\n","protected":false},"excerpt":{"rendered":"
