From strategy to shop floor – across the full battery value chain
Our battery consulting practice combines strategic, operational, and transaction expertise with hands-on engineering capability through our specialist subsidiaries ALEXEC Consulting and PolarixPartners. We work with OEMs, battery manufacturers, integrators, utilities, and investors at every stage of the battery and energy storage value chain – from market entry and architecture decisions through to gigafactory ramp-up and commercial due diligence. The result is guidance that is both commercially rigorous and technically credible.
Our team of over 80 dedicated professionals with deep expertise in batteries spans all major regions and draws on deep cross-sector knowledge across automotive, chemicals, energy, and metals. Clients come to us when the decisions are complex, the stakes are high, and they need an independent perspective grounded in real engineering and commercial experience across every major battery application.
Our solutions
We offer targeted consulting services across the three areas where battery and energy storage decisions are most complex and most consequential.
Strategy and business models
We help clients identify and capture emerging opportunities across the battery value chain — from market entry and growth strategy to partnering models, JV structuring, and new business development. Our work covers demand and competitive analysis, regulatory impact assessment, and technology positioning across EV, BESS, industrial, and recycling segments.
Operations and engineering
We improve efficiency, reduce cost, and accelerate development across battery R&D, manufacturing, and supply chain for grid, EV, and industrial programs. Through Roland Berger and our subsidiaries ALEXEC Consulting and PolarixPartners, we bring together strategic operations consulting with practical capability in pack design, should-costing, supplier auditing, and shop floor optimization – including gigafactory ramp-up and OEE improvement.
Transaction and investor support
We support strategic and financial investors across the full transaction lifecycle — commercial and technical due diligence, vendor due diligence, buy-side advisory, red-flag reviews, target screening, value creation planning, and IPO and carve-out support. Our assessments combine market rigour with technical depth, covering technology evaluation, manufacturing readiness, and regulatory exposure.
