Richard LeCain has been appointed chief technology officer at the UK Battery Industrialisation Centre (UKBIC). “Richard has more than 20 years of experience working in the battery industry, having previously held technical and leadership positions at A123 Systems and Britishvolt,” according to UKBIC. He “has worked in battery plants across the world, transferring processes and designs from the lab into ...

Knowles has introduced two series of triple cell PCB-mount supercapacitor modules, based on Cornell Dubilier’s DGH and DSF series, which it now owns. DGH types work up to 8.1V (-40 to +65°C) and measure between 25 x 8.5 x 16mm high for the 330mF version, to 39 x 13 x 33mm for the 5F. They will also work up to ...

Yamaichi Electronics has added optional CPA (connector position assurance) to its automotive Y-Lock Pullforce board-to-cable connectors for battery management and cell contacting. Found in Y-Lock Version 4, the CPA is located on the stiffener side and latches with the connector when actuated. “The FFC-FPC can only be released after the CPA has been unlocked,” according to the company. “The v4 ...

Nexperia has created a dc-dc converter chip designed to extend the life of 3V primary coin cells in bursty IoT applications, such as those with pulsed radio transmitters. “The IC’s designed to extend the life of a typical non-rechargeable lithium coin cell battery while also increasing peak output current by up to 25x compared to what a typical coin cell ...

Nordic Semiconductor is aiming at cellulat IoT with a system-in-package which puts an RF front-end and a power chip alongside its nRF91 modem and CPU chip. Called nRF9161, it is a globally pre-certified IC “that makes it possible to select either cellular IoT connectivity using the secure cellular infrastructure or use DECT NR+ to realise private 5G networking”, according to ...

Huntsman, owner of the Araldite brand, has developed polyurethane, epoxy and carbon nanotube materials for vehicle battery construction and protection. For underbody battery protection, Rimline (=polyurethane) wet compression moulding material are low-viscosity liquid resins for low-pressure moulding of composites with a high fibre volume fraction – formulated for high-pressure mix machines. Rimline FC (foam core) has flow properties designed for ...

Sodium-ion batteries could be a lower-cost alternative to Li-ion batteries, if ways are found to prevent the large sodium ions destroying their electrodes as they shuttle back and forth. As a possible sodium-ion anode for such batteries, materials scientists at Qingdao University have used titanium dioxide and graphite to produce a stable structure, unchanged after 2,000 cycles. “The researchers found ...

Elastomer electrolytes might be the answer to safe lithium-metal batteries, according to researchers at the Georgia Institute of Technology. Batteries using lithium metal anodes rather than lithium ions promise high capacities, but a tendency to grow internal cell-shorting spike-like metal dendrites makes them a risky, or even unsafe, proposition if liquid electrolytes are used. Solid inorganic or polymer electrolytes can ...

Yokowo has developed a waterproof blade and receptacle connector with floating contacts to absorb mating misalignment, vibration or shock. Spring-loaded dual-beam contacts absorb contact displacement – 0.3mm laterally (left-right in the photo insert), for example. The base of the connector is ~22mm long (including small tags). Contacts are rated at 3A with 50mΩ contact resistance and a life of 2,000 mating cycles. Waterproofness ...

Renesas has introduced a battery pack monitor for long strings of cells that uses an ac-coupled bus to solve the thorny problem of passing data up and down the line. At the same time, it revealed a high-side battery protection and monitoring IC for 4S to 16S cell battery packs. RAA489204 for long strings Stackable up to 30 ICs Up ...
