Panasonic Corporation has released the availability developed a Pin Shaped Lithium Ion Battery (CG-320, nominal capacity 13mAh) with a diameter of 3.5mm and a weight of 0.6g suitable for powering small devices such as wearable devices.

This product, on top of being the industry’s smallest cylindrical shaped rechargeable Lithium Ion battery, features the high reliability and high output required for near-field communications (NFC).

Mass production and shipping are planned to begin in February, 2015 with a monthly production of one hundred thousand units.

The full-scale introduction of wearable device products, anticipated widely as the next wave in mobile devices after smartphones, is expected in a wide variety of applications from 2014.

Rechargeable batteries, the power source for wearable devices, are expected to be not only small and light, but also to have a high level of reliability and performance.

Panasonic has taken advantage of its battery material technology cultivated with lithium ion batteries used in information and communication equipment applications, and coin-shaped and other small lithium battery production technology, to commercialize this battery, which at 3.5mm is the industry’s smallest pin-shaped lithium ion battery.

This product is a rechargeable battery that can be used repeatedly and has the output capability required for NFC.

A stainless steel can is used for the exterior providing for dimensional stability. It will be possible to ensure good design for slim devices such as pen-shaped or spectacles-shaped products.

Panasonic will apply the know-how and technology cultivated from many years of material and production technology development to further expand the line-up of this new product, which is an innovation in battery technology.

The product was on display at CEATEC JAPAN 2014 from October 7th to the 11th at Makuhari Messe.

The industry’s smallest diameter cylindrical rechargeable battery has been developed by using extremely fine components and materials compared to current cylindrical lithium ion batteries, and also by applying the know-how and technology cultivated during the high precision manufacturing process of small coin-shaped batteries.

This product is also the smallest in the industry in terms of capacity by volume, at one twentieth of an AAA size battery (Diameter 10.5mm, Height 44.5mm).

This size is suitable as a power source for small devices such as spectacles-shaped, pen-shaped and other slim devices. Design options can be expanded for these types of communication devices.

Despite the very thin diameter of 3.5mm, the same spiral electrode construction used in current cylindrical Lithium Ion batteries is employed, allowing a wide area between the cathode and anode and resulting in high output.

By succeeding in developing this electrode construction at such a small size, it is possible to use similar materials and achieve high voltage (3.75V) as is seen in current lithium ion batteries.

It is possible not only to operate devices that require high output that would not be possible with current small primary lithium batteries, but also to allow Bluetooth and other NFC*2 with smart phones.

This product provides the output and voltage required by small devices and, as a rechargeable battery that can be used repeatedly, does not require frequent battery replacement.

A high-strength stainless steel can is used for the exterior.

This technology stabilizes the battery dimensions, preventing swelling and allows for confident use of this highly reliable battery.

Jury Finds Meta, Google Liable for Woman’s Social Media Addiction

A jury in Los Angeles has found technology companies, Meta and Google liable for contributing to a young woman’s social media addiction, in a case being described as a landmark ruling.

Jury Finds Meta, Google Liable for Woman’s Social Media Addiction

The 20-year-old woman, identified only as Kaley, argued that she became addicted to Google’s YouTube and Meta’s Instagram from an early age due to their attention-driven design features.

According to her testimony, she began using YouTube at the age of six after downloading the app on her iPod Touch to watch videos about lip gloss and online games.

Kaley told the court that she joined Instagram at nine, bypassing parental restrictions put in place by her mother, and spent extended periods on social media.

The trial, which lasted about a month, with arguments and evidence from both sides.

Jurors also heard testimony from Mark Zuckerberg, chief executive, Meta and Adam Mosseri, Instagram head.

However, Neal Mohan, YouTube chief executive, did not testify.

The jury found that the companies were negligent in the design of their platforms and failed to adequately warn users about potential harms. Meta and Google were ordered to pay the woman $3 million in damages.

Jurors also recommended additional punitive damages, including $900,000 against YouTube and $2.1 million against Meta, according to company spokespersons.

The jury apportioned 70 per cent of the responsibility to Meta and 30 per cent to YouTube.

Kaley was present in the courtroom when the verdict was delivered, alongside parents of other teenagers who say they were harmed by social media use. Both companies said they plan to appeal the decision.

“We respectfully disagree with the verdict and will appeal. Teen mental health is profoundly complex and cannot be linked to a single app. We will continue to defend ourselves vigorously as every case is different, and we remain confident in our record of protecting teens online”, a Meta spokesperson said.

José Castañeda, Google spokesperson, said the case misunderstands YouTube, which is a responsibly built streaming platform, not a social media site.

Nigeria and Finland have signed a Memorandum of Understanding (MoU) on digitalisation and innovation, prioritising stronger cybersecurity cooperation amid a surge in cyberattacks targeting Nigerian institutions.

The agreement was formalised in Abuja on Monday between Dr Bosun Tijani, Nigeria’s minister of communications, innovation and digital economy, and Jarno Syrjälä, Finland’s under-secretary of state for international trade.

The MoU focuses on cooperation in digital governance, technology infrastructure, and cybersecurity to drive economic growth and improve public services, says a statement issued on Monday by Isime Esene, special assistant to the minister.

The agreement is a significant step in strengthening bilateral relations and advancing Nigeria’s digital economy agenda, says Tijani.

He notes the MoU builds on engagements in Helsinki in February, which centred on Nigeria’s Data Exchange Platform and Finnish participation in Project BRIDGE (Building Resilient Infrastructure for Digital Growth and Empowerment).

The talks also involved key Finnish finance institutions, including Finnvera and Finnfund.

The partnership is expected to unlock new opportunities for innovation and investment, positioning digital technology as a catalyst for shared prosperity, says Tijani.

Finland is committed to supporting the development of resilient, secure, and human-centric digital systems in Nigeria, says Syrjälä. He adds that digitalisation should enhance public trust and empower citizens, noting that Nigeria remains a strategic partner for Finland in Africa.

The agreement complements Finland’s lead role in a €23 million Team Europe Initiative aimed at strengthening Nigeria’s digital public services.

This programme is implemented by Finland’s development agency, HAUS, in collaboration with Estonia’s ESTDEV, and supports the 3 Million Technical Talent (3MTT) programme.

The deal comes as Nigerian organisations record the highest number of cyberattacks in Africa. In January 2026, organisations experienced an average of 4 701 attacks per week, a 12% year-on-year increase, according to Check Point Research.

In response, authorities are developing the 2026 National Cybersecurity Policy and Strategy update.

Expected later this year, the framework will mandate minimum cybersecurity investment requirements for organisations operating critical national information infrastructure, notes the ministry.

5 Wealth-Building Strategies for Nigerian Women-led Businesses

Published

Kindly share this post

By Chinwe Iwobi, Head of Wealth Management, FairMoney Microfinance Bank

In Nigeria, women are the backbone of our economy. Data from the National Bureau of Statistics shows that women own approximately 40% of small and medium-sized enterprises across the country (NBS Country Data Overview 2023). Yet despite their outsized contribution to GDP, women-led businesses continue to face systemic barriers to the capital and financial infrastructure needed to scale.

5 Wealth-Building Strategies for Nigerian Women-led Businesses

Chinwe Iwobi

The cost of that gap is not abstract. When these entrepreneurs are held back, the ripple effect runs deep, from household stability to the education of the next generation. But the narrative is shifting. Nigerian women are proving, consistently, that they are not just resilient; they are sophisticated, high-earning innovators building businesses that deserve serious financial strategy.

Here are five foundational strategies every women-led business should be deploying to build lasting, generational wealth.

1. Separate Business and Personal Finances Without Exception

Mixing personal funds with business cash is one of the most common and most damaging financial habits I see among growing entrepreneurs. It obscures your true profit margins, makes tax planning nearly impossible and, critically, disqualifies you from accessing formal credit when you need it most.

The discipline of separation is not just administrative. It is the first signal you send to the financial system that your business is serious. Open a dedicated business account, maintain clean transaction records, and treat your business finances with the same rigour you would expect from any enterprise operating at scale. Clarity on your numbers is the foundation on which every other strategy here depends.

2. Build Both an Emergency Fund and an Opportunity Fund

Most financial advice stops at the emergency fund, which is three to six months of operating expenses set aside for lean periods. That is necessary, but insufficient. The entrepreneurs I have watched grow most aggressively also maintain what I call an opportunity fund: accessible liquidity specifically reserved to move fast when a prime supplier deal, an expansion location, or a bulk inventory discount appears.

In an unpredictable market like Nigeria’s, the businesses that scale are rarely the ones with the best products alone. They are the ones with the financial readiness to act decisively. Products like FairMoney’s FairSave are designed precisely for this, keeping your funds accessible while earning competitive daily interest so your idle cash is working even when you are not. Build both buffers, and build them before you think you need them.

3. Invest Profits Back into Revenue-Generating Assets

Surplus cash sitting in a current account is a slow leak. Inflation erodes it and opportunity costs compound quietly. The discipline here is to consistently channel profits back into assets that grow your revenue capacity, whether that is new equipment, improved technology, better inventory systems, or staff training.

For capital you do not need immediately, consider locking it into a fixed-term savings product that offers higher interest returns. The psychological benefit is as important as the financial one: ring-fencing that capital removes it from day-to-day spending temptation and ensures it is preserved and grown for a defined purpose. Discipline in capital allocation separates businesses that plateau from those that compound.

4. Diversify Your Revenue Streams Intentionally

Single-stream businesses are inherently fragile. If your sole revenue source is disrupted by market shifts, a supply chain breakdown, or a change in consumer behaviour, your entire operation is exposed. Resilience is built by design, not by accident.

If you are in retail, consider adding a service-based arm. If you are service-led, explore whether digital products or training offerings could create passive income alongside your core work. Beyond product diversification, consider how you accept payments. Building a verified, diverse transaction history through formal payment channels also quietly strengthens your credit profile, an asset that pays dividends when you approach lenders for growth financing. FairMoney’s Business POS infrastructure, for instance, allows entrepreneurs to expand their payment reach while simultaneously building that financial track record.

5. Invest Beyond the Business

This is the strategy most women entrepreneurs delay for too long, and it is the one I feel most strongly about. Relying entirely on your business for your net worth is a high-risk position, no matter how well that business is performing. Businesses face cycles; personal wealth should not.

As your business stabilises, begin systematically moving a portion of your profits into personal investment vehicles such as long-term savings accounts, money market funds, or other instruments that sit entirely outside the business cycle. Automate it if you can, so the decision is made once and executed consistently. The goal is to build a personal financial foundation that remains intact regardless of what your business goes through in any given quarter. True wealth is not what your business is worth on paper. It is what you own independently of it.

The Bigger Picture

For female entrepreneurs in Nigeria, wealth-building is not simply a personal ambition; it is an economic argument. When women-led businesses scale, communities stabilise, households invest in education, and local economies deepen. The strategies above are not complicated, but they require consistency and the right financial infrastructure to execute well.

The tools exist. The opportunity is real. What remains is the decision to treat your business, and your personal wealth, with the long-term seriousness both deserve.
