Power lithium battery manufacturers are professional manufacturers of all kinds of batteries, battery packs, so do you know why cell phones with lithium batteries?
Currently, most of the batteries we use come from an ancient model - the original battery in 1800 AD. In the last 300 years, people continue to look for positive and negative materials to improve energy density, whether it is dry cell, nickel-cadmium batteries or the popular lithium batteries, are upgrades of materials. The principle and more than 300 years ago the battery is basically similar.
In fact, the earliest cell phones used nickel-hydrogen batteries, not lithium batteries. After Sony invented the rechargeable lithium-ion battery in 1992, lithium batteries gradually entered our computers and cell phones, becoming the mainstream battery
The battery is composed of positive level, negative level, electrolyte, electrolyte type is relatively small, one is the traditional electrolyte, we call it lithium-ion battery, no other names, there is a class of organic polymer as electrolyte, but the organic polymer is no longer a liquid, we call it lithium polymer battery or lithium-ion polymer battery. These are the two main categories.
Under the two categories, scooter battery manufacturers according to the different materials of the positive level of the battery (negative level materials are mostly graphite), divided into lithium cobaltate lithium ion (polymer, the latter will not be added, the same below) batteries, lithium manganate lithium ion batteries, ternary material lithium ion batteries, lithium iron phosphate lithium ion batteries.
In this, lithium cobaltate cycle number is less, poorer safety, but better capacity, relatively cheap, the most used, the vast majority of cell phone batteries on the market are lithium cobaltate; and ternary materials better performance, in addition to peak current overload can not, other indicators are good, but expensive, so the use of less; lithium manganate safety is good, overload is also good, but the capacity can not, life can not be, with less Lithium iron phosphate life is the best, overload, but the capacity is not, the price is also expensive, in addition to electric vehicles and models are basically not used.
That is, our scooter battery manufacturers currently cell phone battery, is already a better capacity of the material, unless there is again in 1992 Sony invented lithium-ion battery breakthrough, otherwise it will only be a slow upgrade.
