Who better polymer lithium battery and lithium battery?

Source: 2020 - 04 - 12 21:04 hits: lithium polymer battery and lithium battery who better as the commodity market, the emergence of various kinds of power source, power is in the process of consumers to pursue emerge in endlessly. But the safety of the battery can be people's affirmation and acceptance, depending on usage. Polymer lithium battery and lithium battery is a common source of power. Now the question is: what kind of battery is the best? Polymer battery is lithium polymer batteries, lithium batteries, lithium polymer battery and lithium ion batteries have more advantages compared, the following advantages: (summary of polymer lithium battery 1) Large capacity density, and its volume density of nickel hydrogen battery or nickel cadmium battery 1. 5 ~ 2. Five times, and even higher; ( 2) Small self-discharge, placed a long time, small capacity loss; ( 3) The cycle of long service life, normal use life can reach more than 500 times; ( 4) No memory effect, no empty battery before charging, easy to use; ( 5) Safety performance is good, because of physical polymer battery with aluminum composite flexible packaging in the structure, different from the metal shell liquid battery, once the unsafe, it is easier for liquid battery explosion, while the polymer battery will only courage. However, shortcomings are as follows: 1. High cost of battery, the electrolyte purification difficulties. 2. Need to control the protection circuit, overcharge or overdischarge can destroy the reversibility of chemicals, which seriously affect the service life of the battery. The platform of the lithium battery voltage is high; Compared with batteries, lithium batteries with higher energy density. Store high energy density; Lithium battery lighter than lead-acid batteries. Long service life and service life can reach more than 6 years; Lithium battery for both high and low temperature has a strong adaptability. The disadvantage of lithium batteries are: poor safety, explosion risks; Made of lithium cobalt oxide, lithium battery in the big electricity flow can't discharge, poor security. All lithium batteries need protection circuit, in order to prevent the battery overcharge and over discharge. To sum up, if it is compare the safety of the lithium iron phosphate batteries & gt; Lithium-ion polymer battery & gt; Lithium ion battery, but from the cost and consider to have advantages and disadvantages of various practical application so to master the above two batteries battery in favour of a more scientific.
