Polymer Lithium-ion Battery, also known as Polymer Lithium Battery or Lithium Polymer Battery, Polymer Battery.

It is a product specifically defined for the casing shape of lithium batteries, distinct from cylindrical stainless steel and square aluminum shell batteries.

Its composition unit is a polymer lithium battery cell, which is encapsulated with an aluminum foil as the shell, containing a positive and negative electrode membrane, electrodes, separator, and electrolyte. The battery cell is formed by rolling or stacking the positive and negative electrode membranes, followed by high-temperature baking, aging, and static setting to produce the finished lithium battery cell.

By paralleling and串联 the cells, adding dedicated lithium battery protection boards, power cable sockets, connectors, and more, we can Parker (PACK) them into various voltage capacities of lithium battery packs to meet your needs.

Some companies in the industry name models directly with a string of numbers, others use "LP" (lithium polymer) followed by a string of numbers to differentiate between various models, voltages, and capacities. Some use "PL" (Polymer Lithium) as the name. In the early days, there were also names like "PLB" (polymer lithium battery) and "LIB" (lithium ion battery). Adding the letters N, C, M, F, T indicates the main material differences, with these letters representing ternary lithium, lithium cobalt oxide, lithium manganese oxide, lithium iron phosphate, and lithium titanate, respectively.

Based on the different materials, they can be categorized into cobalt acid lithium batteries, manganese acid lithium batteries, nickel cobalt manganese (nickel cobalt aluminum) ternary lithium batteries, lithium iron phosphate batteries, and so on.

Based on the discharge rate, they can be categorized into digital polymer batteries and mid-high discharge rate polymer lithium-ion batteries. The discharge rate for digital applications typically ranges from 0.2C to 0.5C, up to 1C. Mid-high discharge rate polymer lithium-ion batteries can sustain discharge rates of 3C and above, with current technology achieving up to 75C.

According to different application scenarios, they can be categorized into digital, industrial instrument, energy storage, power, and automotive types.

Based on the single cell nominal voltage platform, lithium-ion batteries with ternary polymers are categorized into standard and high voltage (3.8V-3.85V), with corresponding charging cut-off voltages of 4.2V and 4.35V.

Based on the discharge temperature range, they are divided into standard (-20 ~ +60°C), low temperature (-40 ~ +60°C), and high temperature (-20 ~ +85°C).

Based on shape, they can be categorized into standard (rectangular, square) and non-standard (long strip, round, semicircular, triangular, bent, ultra-thin, coin-shaped, etc.).

Based on capacity size ranges, they can be categorized into small capacity polymers (10-1000mAh), standard capacity polymer lithium-ion batteries (1000mAh ~ 100000mAh), large capacity polymer lithium-ion batteries (10Ah+), and most agricultural drone capacities are around 16Ah, 22Ah, and even higher. The capacity of lithium iron phosphate energy storage batteries has reached 300Ah+.
