What are the types of rechargeable batteries?

Source: 2020 - 03 - 25 clicks to him: principles of rechargeable battery rechargeable battery symbol type of rechargeable battery rechargeable battery material is lead-acid battery plate on the active material of lead dioxide, plate on the active substance is the spongy pure lead, to a certain concentration of sulphuric acid electrolyte solution, plate between the electromotive force is about 2 v. Nickel cadmium battery positive plate of the active material of nickel oxide powder, the active material on the negative plate for cadmium oxide powder. The electrolyte is usually potassium hydroxide solution. Open circuit voltage of battery is 1. 2v。 Metal nickel metal hydride battery cathode material for nickel oxide powder, anode materials for hydrogen absorbing alloy, for the potassium hydroxide electrolyte solution. Open circuit voltage of battery is 1. 2v。 Using LiCoO2 composite metal oxides formed on aluminum anode, lithium cathode carbon compounds on the copper plate. The modified polymer li-ion battery is lithium ion battery, no battery fluid, instead of polymer electrolyte, stable than ion battery, open circuit voltage of 3. 6V。 Commonly used parameters of battery capacity says the number of cells can be stored, we see on the battery packaging generally refers to the number of battery capacity. In amp or ma said. It is composed of the product of the current unit and time unit compound unit, said the battery under the condition of constant current continuous discharge capacity. A fully charged battery at 200 ma electrical flow can last 10 hours. With current multiplied by time, and get the battery capacity is 2000 ma. h。 Assuming that discharge 400 ma, time available for 5 hours. : the energy density per unit volume or part contains the amount of energy. Under the same energy, high energy density batteries smaller volume, lighter in weight. C: current battery discharge within one hour after full of traffic, or full of flow of electricity has run out of battery. In fact, it is the size of the volume. 1800 ma。 For a battery capacity, C current is 1800 ma. 2000 ma。 The capacity of a battery, C current is 2000 ma. Open circuit voltage, the battery on the potential difference between the north and south poles. Recall effect: the new battery electrode materials particles is very thin, which makes the electrode surface area is the largest. Due to the use of crystallization of cell contents, composition of crystallization increased, grain increase, also known as ( Passivation) , reduced the electrode area is available, and the increase of grain will constitute the self-discharge increases, resulting in a decline in battery capacity, impaired. This is called the memory effect. Recall the reason is repeat part of the battery charge and discharge is not completely. Self-discharge rate: after the battery, even if not in use, will gradually lose their power, generally the higher the temperature, self-discharge, the more obvious. Nickel cadmium species ( Ni - Cd) Voltage: 1. 2 v life: 500 times the discharge temperature: - Charging 20 ℃ ~ 60 ℃ temperature: 0 ℃ ~ 45 ℃ nickel metal hydride ( Ni - MH) Voltage: 1. Service life is 2 V: discharge temperature: 1000 - 10 ℃ ~ 45 ℃ charging temperature: 10 ℃ ~ 45 ℃ added: the current domestic highest capacity no. 5. About 3000 mah battery. Lithium ion ( Li - Lang) Rechargeable battery rechargeable battery voltage: 3. Lifetime of 6 V: discharge temperature: 500 - : 20 ℃ ~ 60 ℃ charging temperature 0 ℃ ~ 45 ℃ whitening: 30% ~ 40% lighter than nimh batteries, more than 60% higher than nimh battery capacity. It does not, however, resistance to overcharge, assuming the overcharge will form a high temperature and damage structure = & gt; The explosion. Lithium polymer voltage: 3. 7 V500 time of discharge temperature is: - : 20 ℃ ~ 60 ℃ charging temperature 0 ℃ ~ 45 ℃ added: the improved lithium battery, no batteries, but USES the high polymer electrolyte, can be made into a variety of shapes, stable than lithium battery. The service life of the lead-acid battery voltage: 12 v: 200 ~ 300 times: discharge temperature 0 ℃ ~ 45 ℃ : charging temperature 0 ℃ ~ 45 ℃ white: filling is gm battery ( It is made of 62 v series into 12 v) , the number of the service life of the battery do not add water for 10 years, but the volume and capacity is the largest.
