There are several types of lithium batteries

Lithium batteries are usually divided into two categories, namely: 1. Lithium metal batteries, which generally use manganese dioxide as the positive electrode material, metallic lithium or its alloy metal as the negative electrode material, and use non-aqueous electrolyte solution Batteries; 2. Lithium-ion batteries generally use lithium alloy metal oxide as the positive electrode material, graphite as the negative electrode material, and use non-aqueous electrolytes.

Lithium battery classification:

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

According to the packaging materials of lithium batteries: aluminum-cased lithium batteries, steel-cased lithium batteries, and soft-pack batteries.

Lithium batteries are usually divided into two categories:

Lithium metal batteries: Lithium metal batteries generally use manganese dioxide as the positive electrode material, metallic lithium or its alloy metal as the negative electrode material, and use non-aqueous Battery with electrolyte solution. Lithium metal batteries are primary batteries and cannot be used for secondary charging, so they are no longer used.

Lithium-ion battery: Lithium-ion battery generally uses lithium alloy metal oxide as the positive electrode material, graphite as the negative electrode material, and uses a non-aqueous electrolyte.

Lithium-ion batteries can be divided according to their uses:

1. 3C lithium batteries are the batteries used in our daily mobile phones, tablets, laptops, etc.

2. Power lithium battery is a battery used in new energy electric vehicles, drones and other products.

The finished batteries of 3C lithium batteries must be tested before they can be used, mainly to test whether their performance and quality meet the qualified standards. You can choose a high-current shrapnel microneedle module as a connection module. First, it can pass a large current, the current transmission is very stable in the range of 1-50A, and it has a good connection function; second, it can be adapted to small pitches. The minimum pitch value can reach 0.15mm, which is a reliable solution; third, it has an average service life of up to 20W times and can handle high-frequency tests.
