SR button batteries ar志拍e used in calculators, medical de廠員vices, measuring instruments and other快從 equipment

Maxell is the first compan少長y in Japan to successful微請ly produce button silver oxide batt什北eries. Based on propri些冷etary technology in var花放ious fields and years of ex懂個perience, maxell's老信 products can meet the power supply n又相eeds of various types of instruments裡制 (from large to small and thin).


General purpose SR battery is a new著一 product designed by maxell in January紙近 2018. It is suitable for precision水路 electronic equipment requiri跳林ng high energy density and很業 stable working voltage. Maxell divides懂電 SR battery into three categor務土ies according to power consump好一tion in the field of得事 SR battery, namely low-energ聽東y SR battery, general-purpo機商se SR battery and high-energy SR batter來從y. For general equip問慢ment such as calculators, medi廠男cal devices and measuring instrument森男s, general SR batteries are usu問拍ally selected when users do not de又視liberately pursue low battery energy co站風nsumption and want better disc文她harge performance than low energy consu到訊mption SR batteries.

Compare maxell's three志機 SR batteries with di來雪fferent energy consumption:音下


High consumption battery is widely used來樹 in intelligent equipment and can meet 通個the requirements of continuous di是金scharge with large current de舊但mand, but its power consumption is謝民 large and the battery needs科樂 to be replaced frequently;


The consumable battery is 科坐the first choice in the poi什我nter electronic watch, because i朋要ts users care about the ba道森ttery energy consumption and do not w水木ant to replace the bat好劇tery too frequently, b門喝ut its disadvantage is that the廠視 battery discharge performan門上ce is poor and can not support 東新high-performance equipment;


The universal battery compromises the a離到dvantages and disadvantages of the 來吧above two batteries, fur草花ther combines the discharge perf樹慢ormance of the batte還雜ry with the power consumption, and離物 meets the requiremen國個ts of general equipment such a長花s calculators, medical devices and 匠街measuring instruments, which not only 動東optimizes the dischar樂筆ge performance of the battery, b但放ut also improves the綠刀 durability of the bat明見tery.


The internal structure diagram of gen日志eral SR button battery is shown in Fig老數ure 2. It uses silver oxide (Ag2O) 費是as its positive active material, zi去得nc (Zn) as its negative activ民信e material, and sodi城數um hydroxide (NaOH) as el友東ectrolyte.


Reaction chemical equation:

Positive electrode: Ag2O + H2O 少懂+ 2E -- > 2ag + 2OH-

Negative electrode: Zn + 2OH - >鐘數; ZnO + H2O + 2e-

AG 2O + ZnO


General purpose SR bat用新tery has the following adv很河antages:

1. It has stable discharge chara章知cteristics. The discharge curve of費路 the battery is stable until the en區算d of the discharge life.

2. High energy density. Compar草歌ed with alkaline batteri亮慢es, Sr batteries release a匠腦bout twice as much energy per 河章unit volume.

3. Excellent discharge load charact子飛eristics. It adopts alk關師aline electrolyte and has 店通excellent discharge load微計 characteristics. It分東 meets the requirements of general equ作開ipment such as calculators, 場大medical devices and measuring生行 instruments, which 輛離not only optimizes the discharge perf姐我ormance of the battery,水媽 but also improves t外會he durability of the battery.

4. Superior anti leakage te爸著chnology. It adopts maxell's origin不為al leak proof treatment technology,妹妹 which has excellent leak proo很拍f ability and can inhibit electrol能錯yte leakage.

5. Environmental prote業聽ction. Maxell uses its original 靜音technology to achieve mo哥農re lasting and excellent鐘做 anti leakage characteristics without 業自the use of mercury and lead ma訊吃terials.
