The 4680 lithium-ion battery has been long awaited in the electric vehicle industry, and finally, it will enter mass production! This battery carefully developed by Panasonic will not only improve the range, power, and charging efficiency of electric vehicles, but also help reduce costs. It looks like electric car owners will soon be able to get longer range, faster acceleration, and friendlier prices.
Most traditional electric vehicle battery packs use 2170 model batteries, which have a diameter of 21 mm and a length of 70 mm. The 4680 is the "fat man" version of this number, with a diameter that reaches 46 mm and a length that increases to 80 mm. It does seem fatter and longer, but it's not an increase in volume; instead, this design can increase energy density up to five times!
What does this mean? Although this will not directly increase the battery life of electric vehicles by 500%, because the battery itself requires less auxiliary materials, the overall system will be lighter and smaller, which will help for better energy efficiency.
According to the analysis of battery experts, this 4680 battery can also handle higher instantaneous power, which means electric vehicles will have stronger peak output and faster charging. Not only that, this design also performs better in heat dissipation, which increases energy efficiency and allows high power output to last for a long time. And best of all, it's cheaper! This is definitely good news for consumers who are still waiting to buy an electric vehicle.
Although Panasonic has not yet announced the specific specifications of the 4680 battery, they have specially equipped an entire factory in Wakayama Prefecture, Japan. This factory with a size of more than 60,000 square meters will be fully operational for 4680 production. It is expected to start in March next year. By September, the factory will have 400 employees and will be running at full capacity.
In any case, any innovation that can further improve the weight, volume, safety, performance, and cost of batteries based on existing lithium-ion technology is certainly a boon for the field of electric vehicles. We hope that the next electric vehicles will be more powerful and more affordable. art and technique of arranging type to make written language legible, readable and appealing when displayed. The arrangement of type involves selecting typefaces, point size, line length, line-spacing (leading), letter-spacing (tracking), and adjusting the space within letter pairs (kerning).
