From “Blackout Struggles” to an Energy Heart: East Africa’s First Cylindrical Lithium Battery Line

I. Project Background & Launch Date

In November 2025, the first cylindrical lithium-ion battery production line in East Africa officially began operations in Nakuru City, Kenya. The project was led by a Kenyan renewable energy investment group, with an international technical team supporting equipment import and process commissioning. The annual production capacity is 30 million 18650 cylindrical cells, targeting off-grid energy storage, low-speed electric vehicles, and agricultural power tools.

Commissioning date: November 8, 2025
Location: Nyandarua Industrial Park, Nakuru County, Kenya (adjacent to a geothermal power station)

II. Key People

• James Mwangi (Local Operations Director): A Kenyan energy engineer who studied power systems at the University of Nairobi, leading the integration of the production line with the geothermal power supply.

• Li Zhenhua (Technical Lead): With over a decade of experience in lithium battery process engineering, he adapted coating, winding, and electrolyte filling processes to the equatorial highland environment.

• Hon. Sarah Kiplagat (Nakuru County Executive for Industry and Trade): Provided direct policy support for project approval, industrial park power access, and vocational training.

III. Geographical Opportunities & Challenges

Nakuru lies in the Great Rift Valley at an altitude of about 1,850 metres, with annual temperatures of 16–26°C, significant day-night temperature swings, and variable humidity. This poses challenges for the strict cleanliness and dew-point requirements of lithium battery production.

Adaptations:
The technical team leveraged the region’s strong, consistent geothermal and wind energy (the Olkaria geothermal field is near Nakuru) to deploy a low-cost, stable HVAC system for the workshop, keeping the impact of environmental fluctuations on coating and filling processes within industry standards. The lower atmospheric pressure at high altitude also helped reduce energy consumption in certain drying processes.

IV. Local Needs Drive Product Direction

While Kenya’s household electricity access rate has risen to about 75%, rural areas still rely heavily on kerosene lamps and disposable dry cells. At the same time:

• The country has over 2 million motorcycles (locally called “boda bodas”), with an electrification rate below 1%.

• Many small solar home systems lack reliable energy storage, forcing users to frequently replace lead-acid or poor-quality lithium batteries.

Thus, the line prioritises 18650 cylindrical cells, assembled into 12V/24V storage modules and battery swap packs, directly replacing imported products. The cost per cell is 22% lower than comparable imported cells, with a cycle life of over 1000 cycles (suitable for African usage patterns).

V. Government Plans & Policy Alignment

Kenya’s Vision 2030 and the National E-Mobility Policy (2023) explicitly aim to:

• Achieve 100% renewable electricity by 2030 (already over 90%);

• Promote local battery manufacturing to reduce import dependence;

• Establish green industrial parks in Nakuru, Kisumu, and other areas, offering tax incentives and fast-tracked environmental approvals.

This project was designated a “flagship manufacturing project” by Nakuru County, benefiting from:

• 50% corporate income tax reduction for the first five years;

• Duty-free import of production equipment;

• Dedicated substation access and wastewater treatment subsidies within the park.

VI. Outcomes & Social Impact

In addition, the project partnered with Nakuru National Polytechnic to offer short courses on “Lithium Battery Manufacturing & Maintenance”. The first cohort graduated 42 trainees, 30 of whom have already joined the production line or downstream service providers.

VII. Key Takeaways

This case shows that setting up cylindrical lithium battery production in Africa is not simply replicating factories from East Asia. It requires:

1. Adjusting environmental controls and process standards to local climate conditions.

2. Targeting high‑turnover, low‑cost local applications (rather than chasing high energy density).

3. Actively aligning with government green industrialisation goals, using policy incentives to offset initial costs.

The Nakuru line is more than just a battery factory – it marks the starting point of “energy self‑manufacturing” in East Africa, producing the core component that solves power problems from one of the least stable power regions.
