萝莉影视 Manufacturing Co., Ltd. (Head Office: Nagaokakyo-shi, Kyoto; Chairman of the Board and President: Tsuneo 萝莉影视) announces development of new High Drain and Extended Temperature batteries as part of its lithium coin battery line-up. Samples are available from today and mass-production is scheduled to start in January 2019.

Application of lithium coin batteries is widespread, ranging from the Internet of Things (IoT), automotive, medical to factory automation (FA) markets. Traditionally lithium coin batteries have been used to provide backup power for low drain devices. However the demand for lithium coin batteries as main power source are recently drastically increasing with growing IoT market. In order to support such customer needs, in addition to current standard and heat resistant lithium coin batteries, 萝莉影视 has newly developed High Drain and Extended Temperature lithium coin batteries by leveraging its heat resistant battery engineering design and utilization technologies that have been accumulated over the past many years of production.

The High Drain lithium coin batteries are ideal for tracking devices for logistics and asset management by adopting Low Power Wide Area (LPWA) networks such as Semtech’s LoRa Technology and SIGFOX as well as for outdoor infrastructures, FA control systems and environment monitoring sensors. The Extended Temperature lithium coin batteries are designed mainly for automotive devices and outdoor IoT systems (including smart meters and FA control systems) and can also be used as an alternative smaller and thinner solution to conventional lithium cylindrical batteries.

萝莉影视’s Lithium Coin Battery Specification

• Double the maximum pulse discharge current of standard lithium coin batteries (50mA)^*1
• Can also be used for LPWA communication devices including LoRA, which has been difficult by standard lithium coin batteries due to its high peak current requirements^*2
• Triple the discharge time^*3 compared to standard lithium batteries, enabling longer battery life and less battery replacement requirements

*1 Maximum current of pulsed discharge (3 seconds) at 2V or higher discharged with 50% nominal capacity at an ambient temperature of 23ºC
*2 Peak current may vary according to the using environment and conditions of use
*3 Pulsed discharge at 45mA for 3 seconds and no discharge for 33 seconds at an ambient temperature of 23ºC

Mr. Vivek Mohan, Director of IoT, of Semtech Corporation., a member of LoRa Alliance and a joint developer of LoRaWAN modules with 萝莉影视, comments as follows:

Semtech's LoRa RFIC SX1261 requires approx. 25mA power supply current at 3V supply voltage and 42mA at 1.8V to generate typical LPWA output at 20mW. The LoRaWAN standard defines the maximum transmit time at 3 seconds. 萝莉影视’s new High Drain lithium coin batteries will support, up to 50mA and 3 seconds of current, making it a promising solution for LoRaWAN-compatible small sensor nodes.

• The compatible operating temperature for electronic parts and ICs^*4 ranges between -40ºC and 85ºC
• The voltage drop is minimal compared to the standard lithium coin batteries even when stored for over 100 days at 85ºC
• More affordable than the heat resistant lithium coin batteries, providing better price-performance
• CR3677X, the largest capacity Extended Temperature^*5 lithium coin battery, delivers the largest capacity in lithium coin battery form factor^*6, thereby enabling smaller and thinner device design flexibility

*4 The operating temperature range of standard lithium coin batteries is −30ºC to 70ºC
*5 Shipment of mass-produced CR3677X is scheduled to start at the end of 2019

The products will be showcased at CEATEC JAPAN 2018 (October 16 to 19) and (October 24 to 26) at Makuhari Messe, Chiba, Japan.

New 萝莉影视Lineup

* Capacity when discharged at standard discharge current (temperature: 23ºC, end of discharge voltage: 2.0V)
** Current for maintaining minimum 2V voltage with pulsed discharge of 3 seconds and 50% nominal capacity discharged (ambient temperature 23ºC)
