There are several types of lithium batteries

Posted on 2022-08-16

According to the appearance of lithium battery: square lithium battery and cylindrical lithium battery.

According to the lithium battery outsourcing materials: aluminum shell lithium battery, steel shell lithium battery, soft package battery.

Lithium batteries usually fall into two main categories:

Lithium metal batteries: Lithium metal batteries generally use manganese dioxide as the positive material, lithium metal or its alloy metal as the negative material, using a non-aqueous electrolyte solution of the battery. As a primary battery, lithium metal batteries cannot be used for secondary charging, so they are no longer used.

Lithium-ion batteries: Lithium-ion batteries generally use lithium alloy metal oxide as the positive material, graphite as the negative material, using non-aqueous electrolyte batteries.

Lithium-ion batteries can be divided into:

One, 3C lithium battery, is our daily use of mobile phones, tablets, laptops and so on the battery.

Second, power lithium battery, is the battery used in new energy electric vehicles, drones and other products.

The finished battery of 3C lithium battery has to be tested before it can be used, mainly to test whether its performance and quality meet the qualified standards. Can choose high current shrapnel microneedle module as the connection module, one is through the large current, in the range of 1-50A current transmission is very stable, with a good connection function; Second, in small pitch, the minimum adaptive pitch value can reach 0.15mm, with a reliable solution; Third, it has an average service life of up to 20W times, which can deal with high frequency testing.
