In the eyes of electrochemical res術通earchers, the element自西s scattered in nature are not 商道just the composition of li地黑fe. They are like scatt妹報ered puzzles. Differ畫票ent elements and ions can form differen年她t electric energy. T議東hey may be alkaline batteri習筆es, carbon batteries or lithium batter內習ies. How do they convert chemical e書笑nergy into electrical energy step b麗舞y step? How do they seal t我化hese different energies in th厭錯e battery?

Electrochemistry is the science 答員of studying the phenomenon of b睡嗎and point interface formed 她事by two kinds of conductors and the cha她紅nges in it. Generally, there are t鄉去wo aspects: one is the study of el歌文ectrolyte, the other is the stu錯件dy of electricity.

Before making a battery, we sh嗎如ould study its chemical principle, unde和計rstand the composition of a b很男utton battery, what substa上費nces and materials are needed 場玩to seal it. For example, Nanfu C近人r32 button battery is 從器composed of positive shell,得章 negative cover, electrolyte, diaphra鐘窗gm, etc. As shown in the figur窗西e, the principle is not complic做路ated and the material生輛s needed are not much, 時服but why can't we make batteri讀劇es ourselves? In fact, batter暗樹y production is much more difficult t技你han we think.

Recently, we were invited to visit又也 Nanfu battery, a battery enterpr樹又ise, and we visited its button bat國車tery production workshop. It is said為河 that both the company'微年s button battery and Panasonic&化票#39;s button battery have可頻 become famous button風城 batteries in the industry. We sigh t黑筆hat domestic forces are ri農著sing!

It is reported that a Nanfu Cr32日小 button battery takes at least 22 da不習ys from production to delivery, which 懂微requires many steps o村但r procedures. Sure enough, rigorous 校為production can create the quality of p劇現roducts, and there is now Nanfu batte海花ry! Out of curiosity, we a林時sked relevant personnel about the討鄉se processes. We understand that th來議ere are these processes:

Dry raw materials, assemb得鐘le batteries, clean batteries, p水些re discharge, aging, aging, e拿事lectricity inspection, card hanging 了子and packaging.

We asked them why they need so信北 many processes? Is it for quality就個? Will this be much differ議裡ent from other button batt著鐵eries?

Relevant personnel explained this to業件 us because Nanfu sh要文aped ring battery has 紅科long been known, and服林 the button battery as a battery can n國信ot fall behind, so consumers can r美唱est assured. Strict pr算鐘ocess requires high precision and ma男睡terials, so it needs to be dr音飛ied. A separate drying system keeps物很 the materials at a constant te報視mperature, simulates the batt視算ery environment through pre discharg術街e, aging and aging, and th地服en tests the voltage risk and current 訊信of a button battery thr黃資ough electricity inspec人志tion, so as to judge whethe從報r it is good or not, and those who d愛姐o not meet the standard wi路子ll be eliminated.

However, we didn't thi那道nk Nanfu Cr32 button battery房相 was so strong. Later, we exp人店erimented on the spot. We brought but笑鐵ton batteries of other brands and N請西anfu Cr32 button battery from the outs水要ide. They were successive請哥ly installed on the same car rem放機ote control. Press the r著什emote control at different distan視街ces to test the vehicle respo哥舊nse. The results show that Nanfu'嗎他s button battery is 河視indeed stronger. It can unlock the car 我可at a relatively far positi美都on, and the ordinary 音路button battery can only reach 3照水5 meters. This is becau微老se our car remote control is pul紅間se discharge, which belo笑購ngs to high current and high termina服這tion voltage type.

The strong unlocking of the如姐 car does not mean that its electric e道從nergy is stronger than others. Later, 樂高we came to Nanfu laborator謝新y and saw that it is testi跳短ng electric energy. The窗房 test results show th跳數at Nanfu button battery is妹志 really strong and can be費舊 used in the CR2032 button battery w綠冷ith the characteristics票林 of large capacity an業票d mercury free. At 1K Ω and 下匠2.0V discharge, the CR2032 batter業和y achieved a long life of 8不人8.86 hours.

At the end of the interview市子, we lamented the rapid development 坐和of science and technology in the mo低雜therland. We hope that more and more 可姐domestic products wil鐵友l become stronger an線要d stronger, and China will become 開下more and more beautiful山國. Science and technology has been 雪上developing and changing老答 and stands in the world.
