ARBOK-HABP (Hybrid Acid-Alkaline Battery Pack) — product name: GrapheneCell HX

Overview

ARBOK-HABP is a BT1-compatible hybrid acid-alkaline battery pack proposed as an alternative to GM's Ultium 24-module system for heavy EVs. It combines a low-cost lead-silicon acid block, a long-life nickel-zinc alkaline block, thermo-exfoliated graphite electrodes, a switchable DC/DC interface, and an integrated supercapacitor burst module in a composite monocoque — claiming higher energy density, lower cost, better thermal performance, and faster charging than Ultium, while lighter and easier to service.

Applications

Primary use cases: heavy-EV traction packs (GM BT1/Hummer EV, DANNAR); high-power stationary storage.

Industries and users: EV OEMs and integrators, heavy-equipment electrification.

Scale: 24-module pack (~220 kWh); modular swap.

Operating Principle

Dual-chemistry pack: a lead-silicon acid block (low cost, recyclable, overcharge-resistant) and a nickel-zinc alkaline block with graphite cathode (long cycle life, dendrite-free, fast-charge capable), each built from multiple modules, bridged by a switchable dual-voltage DC/DC converter and a central supercapacitor buffer for burst power, all managed by a dual-chemistry-aware BMS + thermal AI. Thermo-exfoliated graphite electrodes with advanced carbon-based additives give very high thermal conductivity for fast charging without liquid cooling.

Limitations: design-proposal stage; dual-chemistry integration complexity; OEM qualification.

Key Parameters

Acid and alkaline blocks combine lower-cost energy storage with higher energy density and long cycle life, balanced to give the pack its overall cost and performance profile. A supercapacitor buffer supplies high-power bursts for acceleration and regenerative braking demands.

Electrodes: thermo-exfoliated graphite composite with advanced carbon-based additives, giving very high thermal conductivity for high-power DC charging without liquid cooling. Enclosure: lightweight carbon-fiber monocoque, substantially lighter than a comparable steel structure; fast, modular service swap.

Pack: ~220 kWh usable, 980 kg, ~$68/kWh, 520 kW charge (10→80 % <12 min), 5 500+ cycles, ~395 mi range.

Architecture and Components

Lead-silicon acid block; nickel-zinc/graphite alkaline block; central supercapacitor; switchable dual-voltage DC/DC; BMS + thermal-AI; carbon-fiber/graphite monocoque enclosure. BT1-compatible mechanical and electrical interface — standard mounting flange, structural rating, and CAN/open-API connectivity matched to the GM BT1 platform.

Advantages

Technical: hybrid chemistry (cheap acid energy + durable alkaline cycling); 520 kW charge without liquid cooling; <12 min fast charge; 5 500+ cycles; composite monocoque (no welds).

Economic: ~$68/kWh vs ~$130/kWh Ultium (−48 %); −23 % mass; IRA bonus (+$45/kWh, no cobalt/nickel → +$9M per 1 000 packs).

Environmental: 100 % recyclable acid block, no cobalt/nickel.

Strategic: Ultium alternative amid lithium price shocks (>$200/kWh NMC by 2026).

Integrations

Drop-in for GM BT1/Hummer EV and DANNAR platforms (dimensions, mounting, voltage, CAN); commercial models: prototype+integration, low-volume supply, Battery-as-a-Service lease, or IP licensing.

Deployment & Operation

9-month roadmap: NDA → simulation and single-module validation → full-pack prototype → crash and fast-charge validation → Hummer EV integration → serial contract. Fast, modular service swap.

TRL

TRL 3 (confirmed by Michael). Detailed design proposal with full architecture and a 9-month prototype roadmap; no built pack yet. Remaining: module-level and full-pack prototype, validation.

Market Potential

Heavy-EV packs face lithium price shocks and Ultium's closed chemistry. A cheaper, lighter, cobalt/nickel-free hybrid pack with IRA bonuses targets BT1/DANNAR and broader heavy-EV/storage markets.

Typical Project Economics

~$68/kWh production vs ~$130/kWh Ultium. Engagement: prototype+integration ~$4.8M (9 mo); low-volume ~$14 960/pack (100/yr); BaaS $0.22/kWh-month (36-mo lease); licensing 8 % of verified savings. IRA: +$9M per 1 000 packs.

Risk Factors

Design-proposal maturity (no built pack); dual-chemistry integration and safety validation; OEM qualification (BT1); Ni–Zn/Pb-Si supply and cycle-life proof; aggressive performance claims to validate.
