Instructies en voorzorgsmaatregelen voor het gebruik van lithiumthionylchloridebatterijen

Lithiumbatterijen met een modelnummer dat begint met ER zijn lithiumthionylchloride (Li/SOCl2) batterijen, die volgens internationale batterijnormen zijn geclassificeerd als primaire lithiumbatterijen. Lithium primaire batterijen zijn een nieuw type hoogenergetische en milieuvriendelijke batterij met lithiummetaal als negatieve elektrode. Het zijn niet-oplaadbare batterijen.

1. Lithium primaire batterijen zijn niet-oplaadbaar
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. Voorkom geforceerde ontlading
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. Hoge temperatuur
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. Hysterese en aandachtspunten
As lithium thionylchloride batterijenhebben een kenmerk, dat wil zeggen spanningshysterese, waardoor klanten de batterij vaak gebruiken om een hoge stroom te leveren, en de belastingsspanning is lager dan de minimale limietspanning van de klant, waardoor de apparatuur slecht werkt. Gezien het feit dat veel klanten dit onderschatten, is het voor ons noodzakelijk om de hystereseprestaties van de batterij in detail uit te leggen.

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).

Daarom moeten klanten het hysteresefenomeen volledig begrijpen en overeenkomstige maatregelen nemen om de impact van hysterese te verminderen. De volgende suggesties worden gedaan tijdens het daadwerkelijke gebruik:
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. Voorzorgsmaatregelen tijdens het gebruik

1. Kortsluiting is ten strengste verboden en opladen met hoge stroomsterkte is ten strengste verboden.

2. Het is ten strengste verboden om zelf batterijen te combineren.

3. Overmatig ontladen, knijpen en verbranden van batterijen is ten strengste verboden.

4. Langdurig gebruik of verwarming buiten het toegestane temperatuurbereik is ten strengste verboden (batterijen lopen veiligheidsrisico's bij overschrijding van 100°C).

5. Controleer voor gebruik de buitenverpakking streng. Als de verpakking beschadigd is, zoek dan de oorzaak op en gebruik deze niet gemakkelijk. Wanneer de verpakte batterijen verspreid zijn, sorteer ze dan op tijd, verzegel de verspreide batterijen en waarschuw de leverancier.

6. Het is ten strengste verboden om batterijen van verschillende series en verschillende specificaties in serie te mengen en te gebruiken.

7. Solderen kan niet naar believen worden uitgevoerd op de bovenkant van de positieve en negatieve polen van de batterij, en het solderen op de lead-out sheet moet binnen 5 seconden worden voltooid.

8. Tijdens het gebruik kan de batterij niet worden verspreid of laten vallen om kortsluiting van de batterij te voorkomen.

9. Nadat de batterij is ontladen tot de eindspanning, is het ten strengste verboden om deze verder te gebruiken en kan de batterij niet in water worden gedrenkt.
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.
