What is Battery Multiplier?

Battery multiplier is mainly the performance of a battery in charging and discharging. The value of current needed to release the rated capacity at a specific time, battery multiplier is usually expressed as C.

Discharge multiplier refers to the amount of discharge at the same time compared with the conventional discharge, several times the conventional discharge.

Generally, the size of the charge/discharge current is often used to express the charge/discharge multiplier, charge/discharge multiplier = charge/discharge current / rated capacity. The charge/discharge multiplier of a lithium-ion battery determines the charge/discharge time of the battery.

What is a high rate battery?

High-multiplier batteries are usually lithium-ion batteries, in the process of charging and discharging, Li+ is embedded and de-embedded back and forth between the two electrodes: when charging the battery, Li+ is de-embedded from the positive electrode, and embedded in the negative electrode via electrolyte, and the negative electrode is in the state of lithium enrichment; the opposite is true when discharging.

When charging 0.2C ~ 2C is usually the capacity battery, 2C or more batteries are called power batteries. 10C or more batteries are collectively referred to as high rate batteries. For example, a 20Ah battery discharged at 2C is 40ah, while a 0.5C battery is 10ah.

The difference between high rate lithium batteries and low rate batteries?
  • Energy density: high rate battery energy density > low rate lithium battery.
  • Charging speed: high rate lithium battery charging speed > low rate battery.
  • Cycle life: high-magnification battery cycle life<low-magnification battery.
  • Safety: safety of high rate battery<low rate battery (high rate generates more heat when discharging)
What is the performance of high rate lithium batteries?
  • There is a high discharge rate: high rate batteries can release a large amount of current in a very short period, which is useful for applications that require instantaneous high-power output (e.g. drones, high-performance RC cars, power tools, etc.).
  • High power density: under the same volume or weight, high-rate batteries can have higher power density.
  • Cost: high rate batteries both cost and other materials need to use higher-end materials to meet the needs of high rate.
Lithium-ion battery high rate of charge and discharge capacity is mainly related to what factors in the battery?

The most important is the material, and then the supporting electrolyte, the diaphragm.

  • Core material: mainly composed of lithium iron phosphate and nickel-cobalt-manganese (or aluminum) ternary material, ternary material is better than lithium iron phosphate.
  • The structure of the material: to facilitate the de-embedding and insertion of ions, and the essence of the multiplier performance is that the ions can be quickly de-embedded from the main material and through the electrolyte, diaphragm inserted into the other end of the main material, which requires the material to have a stable and easy to de-embedded ions in the structure.
  • Electrolyte influencing factors: in the process of charging and discharging, the size of the internal resistance of the battery not only determines the size of the battery over-potential but also affects the temperature rise of the whole battery. When the temperature rises to a certain degree, not only does the electrolyte decompose, but also destroys the structure of the SEI membrane, affecting the cycle and safety performance of a closed lithium-ion battery.
What are the main areas where high rate batteries are used?

Small high rate batteries: mainly used in power tools, electric bicycles, electric boats, drones, etc.
Large high-rate batteries: mainly used in EV, PHEV, and HEV power vehicles.

Which is better, high or low rate battery?

High-rate is usually a power-type battery, and the priority requirement is the current output capacity. Commonly found on racing models, they are expensive.

Low-magnification is a capacity-type battery, commonly found on devices with energy storage requirements such as rechargeable batteries, with lower technical requirements and affordable prices.

This problem will need to choose the high and low multiplier battery pack according to their own needs, and there is no good or bad of that battery, just different application scenarios.

Can high-rate batteries be fast-charged?

High-rate batteries usually support fast charging, but charging needs to ensure that the charging current will not exceed 1C.

What are the adverse effects of a high rate lithium battery (e.g. 10C) operating at a low rate (e.g. 0.1C) for a long time?

Low rate discharge depth is usually higher than high rate discharge depth, too much discharge depth may lead to battery cycle performance deterioration, but there is no use for lithium-ion batteries whose discharge rate can’t be lower than how many C’s. Li-ion battery low rate discharge has no effect, but rather than high rate discharge cycle life and other aspects are higher.
