How do I take AA battery apart?

AAAAA commonly known as 5, 7The battery, in daily life, the most common, and the clock they are widely used remote control toys radio flashlight and so on. This kind of battery is one-off, rechargeable cycle, such as nickel cadmium also have AAAAA, nickel-metal hydride manufacturers are of variable quality, the price also is different price of some high performance is very poor, today bring is a resistance from Guangzhou when battery technology co., LTD. The production of lithium iron batteries, performance is good and then looked down.

A, appearance

The packing bag of blue two sets of four grain of AA batteries

Pocket size design, easy tear open mouth encryption seals easy to use, packing bag with hook hole storage when is convenient to receive in the middle

The appearance of the blue and white, the weight of 15 g was quite good

Double festival show

Electricity grading scratch, as long as gently scraping can quickly distinguish between old and new batteries

Negative bright dazzling second, the test article

Do a simple capacity test, no-load voltage of battery 1.8 V to 1.5 V dry cell above normal, but the voltage on the electrical appliances will not have a problem, not 1.8 V battery voltage platform, pick up the load will be down soon.0.2 C discharge rate test capacity is 2852 mAh, the data has been seconds kill all known domestic brands, AA battery, titles defeated the standings.

Because there are certain risks and dismantling, dismantling must take energy batteries discharge, even to a short circuit to the end to verify the battery have electricity.Continue to squeeze the lithium iron batteries, released 3225 mAh this data is a little accident, once again proved that electric toy after use, put the remote control also can be used then.Three, disassembly

You tear the outside of the packaging film of the battery

Batteries positive and there is a layer of transparent insulation between steel shell

With the Angle grinder, the anode side cut a mouth, biting tear with forceps

The positive part, there is a pole ear spot welding on the anode cap, can see rows of white diaphragm around together, similar to lithium battery winding structure of

Continue to tear down around, to tail when he saw a piece of copper pole ear and steel shells pressed together

Separate tail, anode and copper without any welding, the bottom has a black circle of insulation used to isolate the cathode copper

Have a look at the positive relief valve insulation situation first, transparent insulation package as a whole

Forced to separate, unexpectedly has three combination

Relief valve by the explosion proof and anti-short circuit valves fit, it is also an important part of essential to high energy battery, and common 18650 has a similar structure, it is such a design would not short circuit

Start winding structure, saw large black substance, naked lithium battery structure, should use a unique way to make voltage control in rather than 3.2 V or 1.5 V3.7 V lithium battery

Spread to the central part of it was wrapped in the anode the nickel belt and segregated with high temperature tape, tear tape, we have a look at the positive pole

Negative part list, before open too soft bag adopts do battery cathode copper foil, the lithium iron battery USES the same plan the brutality of the scene filled with a special flavor, haven't seen any visual liquid, according to the winding structure diaphragm adsorption electrolyte, completely to the leakage is difficult.And disassembly process, winding materials are fever, after that let the normal discharge measurement, some energy is not released, further illustrate with small ratio, when using lithium iron battery power is more than 3000 mah, is more than friends.

Many components in dismantling end summary: when lithium iron batteries with high resistance ability to low temperature high battery life security, many characteristics such as green environmental protection, more durable than ordinary alkaline battery a few times, similar to the winding structure of lithium-ion batteries to make solid foundation for high capacity. Diaphragm adsorption electrolyte, completely don't have to worry about for a long time use leakage condition, thus our equipment corrosion. Resistance of lithium iron batteries when design thinking ahead, many special features in one hit the market with low prices, to paraphrase words of classic section more than three, are you still hesitating?
