Upute i mjere opreza za upotrebu litij-tionil kloridnih baterija

Litijeve baterije s brojem modela koji počinje s ER su litij-tionil kloridne (Li/SOCl2) baterije, koje su klasificirane kao litijeve primarne baterije prema međunarodnim standardima baterija. Litijeve primarne baterije nova su vrsta visokoenergetskih i ekološki prihvatljivih baterija s litij-metalom kao negativnom elektrodom. To su baterije koje se ne mogu puniti.

1. Litijeve primarne baterije se ne mogu puniti
Directly charging lithium primary batteries will cause the battery to explode. The probability of battery explosion is directly related to the charging time and current. 220V charging will explode instantly. 12V DC charging, the battery will explode within a few minutes. 5V DC charging without external protection components can reach a charging current of about 50mA, and the battery will explode after a few hours.
In the case of 5V voltage floating charge in the circuit, it is recommended that customers add diodes and other protection measures in the circuit to control the charging current below 10µA.
It is safe to control the charging current of lithium primary batteries below 10µA.

2. Spriječite prisilno pražnjenje
When several batteries are used in series, if other models or used batteries are used in the series battery, some batteries will experience forced discharge (OverDischarge). Due to the unevenness of battery capacity, some batteries will charge in the later stage of discharge, which may cause battery accidents.
To prevent the occurrence of charging, customers are advised not to assemble batteries for use.
If you want to use a single battery in combination, please contact the technicians, who will provide you with assembly solutions and assembly design services.

3. Visoka temperatura
When the ambient temperature of the lithium primary battery exceeds 100°C, the battery will explode, so you should pay attention to controlling the welding time and temperature during welding.

4. Histereza i točke pažnje
As litij-tionil kloridne baterijeimaju karakteristiku, odnosno histerezu napona, zbog čega kupci često koriste bateriju za pružanje velike struje, a napon opterećenja niži je od minimalnog graničnog napona kupca, što uzrokuje loš rad opreme. S obzirom na činjenicu da mnogi kupci to podcjenjuju, potrebno je detaljno objasniti histerezne performanse baterije.

Class A: Under low current conditions, although the battery is passivated, the load will not change significantly when in use. Taking ER14250 as an example, when the current is below 1mA, the battery will not have obvious hysteresis (voltage reduction).
Category B: Under medium current conditions, if the battery is passivated, but the battery load can still be maintained above the cut-off voltage.
Taking the ER14250 battery as an example, when the current is below 4mA, the voltage of the passivated battery will drop, but generally will not drop below 2.8V.
Category C: Under high current conditions, if the battery is passivated, the battery load can easily drop below the cut-off voltage, causing the device to fail to work properly. Taking the ER14250 battery as an example, when the current reaches more than 10mA. If passivated, the load will drop below the cut-off voltage (Cut-offVoltage).

Stoga kupci moraju u potpunosti razumjeti fenomen histereze i poduzeti odgovarajuće mjere za smanjenje utjecaja histereze. Tijekom stvarne uporabe daju se sljedeći prijedlozi:
1. Consider the load size, use environment and other factors in the design stage, and select a battery model for use under medium or low current conditions.
2. The finished battery inventory time should not exceed half a year. It is recommended to activate the battery after more than half a year.
3. If the battery is installed on the device and has micro-ampere power consumption, the battery passivation phenomenon is slowed down. However, if the design current is greater than the maximum battery operating current, it is recommended to consider adding capacitors during the design phase to reduce the battery voltage drop.

V. Mjere opreza tijekom uporabe

1. Kratki spoj je strogo zabranjen, a punjenje velikom strujom strogo je zabranjeno.

2. Korisnicima je strogo zabranjeno samostalno kombiniranje baterija.

3. Pretjerano pražnjenje, stiskanje i spaljivanje baterija strogo je zabranjeno.

4. Dugotrajna uporaba ili grijanje izvan dopuštenog temperaturnog raspona strogo je zabranjeno (baterije imaju sigurnosne opasnosti kada prelaze 100 °C).

5. Prije upotrebe strogo provjerite vanjsku ambalažu. Ako je ambalaža oštećena, otkrijte uzrok i nemojte je lako koristiti. Kad su zapakirane baterije raspršene, razvrstajte ih na vrijeme, zatvorite razbacane baterije i obavijestite dobavljača.

6. Strogo je zabranjeno miješati i koristiti baterije različitih serija i različitih specifikacija u seriji.

7. Lemljenje se ne može izvesti na vrhu pozitivnog i negativnog pola baterije po želji, a lemljenje na izlaznom listu mora se završiti u roku od 5 sekundi.

8. Tijekom rada baterija se ne može raspršiti ili ispustiti kako bi se izbjegao kratki spoj baterije.

9. Nakon što se baterija isprazni do završnog napona, strogo je zabranjeno nastaviti je koristiti, a baterija se ne može namočiti u vodi.
10. Used batteries should be marked and scrapped in time, and should not be stored randomly.
11. When stripping and welding wires, do not strip the positive and negative wires at the same time, and do not connect the positive and negative wires with metal objects to avoid battery short circuit.
12. When packaging and storing surplus batteries from the production line, the batteries should be packed in the original packaging, neatly arranged, and not short-circuited with each other.
13. Surplus batteries from the production line should be stored in the original packaging. It is recommended that the battery be stored in an environment with a temperature of <25 degrees and a humidity of <70% to avoid long-term storage in harsh environments, which may cause rust and corrosion of the battery and cause leakage.
14. Requirements for battery installation and use: The positive pole of the battery cell should be placed horizontally and upward. When the positive pole is downward, part of the capacity will be unusable, and the actual utilization rate is only about 80% of the normal value.
15. Keep the battery away from children to avoid injury.
16. Scrapped batteries cannot be destroyed by themselves, and should be handled in accordance with the regulations of the local environmental protection department.
The above are the precautions for the use and operation of lithium primary batteries, which are hereby explained.
