Panasonic Corp. is gearing up to become a major manufacturer of a new, more powerful battery championed by Tesla Inc. that the electronics maker says meets the demands of its high-flying customer.
Over the past year and a half, Panasonic has been working to develop a bigger ¡°4680¡± battery it intends to sell to the American electric carmaker. Because of the battery¡¯s larger volume, fewer cells and related parts are needed to power an electric vehicle, leading Tesla Chief Executive Officer Elon Musk to tout the technology as the key to unlocking $25,000 (?2.9 million) EVs.
Developing the new batteries has ¡°taken an immense amount of stamina¡± over the past months, Kazuo Tadanobu, chief executive officer of Panasonic¡¯s energy business, said during a recent interview at the company¡¯s headquarters in Osaka.
