Among the various components involved in a lithium-ion cell, cathodes (the positive or oxidizing electrodes) currently limit the energy density and dominate the battery cost. Today’s common cobalt (Co) and manganese (Mn) based cathodes were developed to overcome safety concerns with Li-metal anodes. This FAQ begins with a brief look at the longer-term trajectory of…

Battery management system uses ultra-thin pressure and temperature sensors
Innovation Labs has announced the BaMoS battery monitoring system that uses ultra-thin printed pressure and temperature sensors to capture detailed battery data down to the individual cell level, which can be used to extend battery lifetime by up to 40 percent. The battery is the most important component in an electric vehicle (EV). Despite extensive […]
Modules help add wireless charging to small devices
Rohm Semiconductor announced they have developed compact wireless charger modules with an integrated antenna board: the BP3621 (transmitter) and the BP3622 (receiver). These new modules allow designers to add wireless power supply functionality to smaller devices such as smart tags/cards or PC peripherals. Wireless power supplies are increasingly being adopted in smartphones, smart watches, and other compact devices. […]
What to consider when evaluating battery performance
Several important metrics and considerations are important when evaluating battery performance: Cell, module, and pack level: It is important to consider whether the data refers to an individual cell or a complete battery pack when comparing energy and power densities. Cells will always have the highest energy and power for a given size or weight.…
Low-voltage MOSFETs feature low Rss(on) for smartphone battery PCMs
Magnachip Semiconductor Corporation announced the launch of a new generation Low-Voltage Metal Oxide Semiconductor Field Effect Transistors (LV MOSFETs) featuring lower Rss(on) for battery Protection Circuit Modules (PCMs) in smartphones. As demand for high-end 5G and LTE smartphones increases, extended battery life and strengthened protection features for batteries are becoming important. 5G phones, in particular, need long-lasting […]
Compact contactors handle up to 250 A dc, 1,000 Vdc
TDK Corporation has extended its range of bipolar DC high-voltage contactors to include the new HVC43 (B88269X3**0C011) series. These products complete the existing range by offering continuous currents from 150 A DC to 250 A DC and operating voltages of up to 1000 V DC. The contactors are available in 12 V or 24 V […]
Current-sensing foil-on-ceramic resistors sport 2 milliohm resistance
High efficiency in consumer electronics has become increasingly important. For portable electronics, this means lower resistance values on current sense resistors for battery and power management. Stackpole’s CSRF series is a foil on ceramic carrier chip resistor that is designed for these applications. The CSRF2512 is now available in resistance values down to 2 milliohms. […]
Battery management system enables battery hot swapping in low-voltage EVs
Sensata Technologies announced the availability of its new i-BMS battery management system (BMS) for electrified applications up to 60V. The new i-BMS Battery Management System from Sensata’s Lithium Balance product brand, acquired by Sensata earlier in the year, is cell chemistry agnostic, compact, integrated BMS developed for the cost-optimized mass-production of applications up to 60V, such as […]
