Tesla Battery Day: More efficient batteries, new AU$35,000 model coming

Tesla's much-hyped Battery Day has indeed delivered a new type of battery cell, which the company says will provide a 16 per cent increase in range. Theoretically, this means a Tesla Model S could offer a range of up to 750 kilometres on a single charge. The new Tesla battery, named the 4680 for its dimensions (46mm by 80mm), reportedly provides five times the energy and six times the power of previous comparable cells.
