Rechargeable Lithium Battery

RECHARGEABLEBATTERY should be written "rechargeableBattery", and the rechargeable battery will generally indicate the capacity of the battery, such as 1600mAh, 2000mAh, there will also be a logo of the type of rechargeable battery, such as Ni-MH (nickel metal hydride), Ni-Cd (nickel cadmium), currently there are five categories on the market: Nickel cadmium, nickel metal hydride, lithium ion, lead storage, iron lithium.

As it says, warning:battery may explode or leak if recharged or disposed of in fire. This is not a rechargeable battery.

If it is a rechargeable battery, it will write please pay attention to 1: battery do not put in, do not short circuit, disassemble. 2: How many hours of standard charge, how many hours of fast charge. 3: Charge or use, please check the correct position of the electrode, avoid backcharging or short circuit.

Materials for rechargeable batteries

The active substance on the positive plate of lead-acid battery is lead dioxide, the active substance on the plate is spongy shape pure lead, the electrolyte is sulfuric acid solution of a certain concentration, and the electromotive force between the plates is about 2V.

Lithium polymer battery is an improved version of lithium ion battery, no battery liquid, use polymer electrolyte, more stable than ion battery, open circuit voltage 3.6V.

Main advantages of rechargeable Lithium Battery 1, high rated voltage. The operating voltage of a single lithium battery is 3.7V or 3.2V, which is about equal to the series voltage of three nickel-cadmium or nickel-metal hydride rechargeable batteries, which is convenient to form a battery power bank. 2, with high power bearing capacity. Among them, the lithium ferrous phosphate lithium ion battery used in electric vehicles can reach 15-30C charging and discharging capacity, which is convenient for high-intensity start-up acceleration; 3. The self-discharge rate is very low. This is one of the outstanding advantages of the battery, currently generally can do less than 1%/ month, less than 1/20 nickel metal hydride battery; 4. Light weight. The weight of the same volume is about 1/5-6 of the lead acid product.
