BAK Battery: Pioneering Energy Storage Advancements

On May 24th, the 13th CIES conference took place at the InterContinental Hangzhou, focusing on the theme of "Advancing the New Energy System and Promoting High-Quality Development in the Energy Storage Industry." During this event, significant discussions and exchanges occurred regarding key, trending, and challenging issues faced by the energy storage sector.

Shenzhen BAK Power Battery Co., Ltd., an early player in China's energy storage field, showcased its core products in energy storage at the CIES. These products included large prismatic batteries and home storage units, and BAK Battery shared innovations in enhancing cell performance, versatile applications, and tailored services.

Energy storage plays a crucial role in addressing the intermittent nature of wind and solar power, underlining its importance in the green and low-carbon industry. While China's energy storage industry is still in its early stages, it holds immense growth potential and market opportunities. Projections suggest that by 2025, new energy storage will enter a phase of large-scale development, with full marketization expected by 2030, reaching an estimated domestic market size of 10 trillion RMB.

To seize these opportunities and overcome challenges, BAK Battery follows a value concept for energy storage based on "Technology + Layout + Market" and initiated its strategic plan in advance. In 2019, BAK Battery participated in constructing one of the initial photovoltaic (PV) energy storage joint demonstration projects in Xinjiang, achieving successful grid connection. Currently, BAK's energy storage battery products find application in various sectors, including residential, industrial, commercial, UPS, power grid, communications, and customized power supplies. This expansion represents a significant leap in integrated delivery capabilities, encompassing battery modules, energy storage systems, container energy storage systems, and other solutions.

BAK's energy storage batteries feature modular design and come equipped with an intelligent battery management system (BMS). They offer advantages such as compact size, lightweight, extended lifespan, high-temperature resistance, and support for large current discharge. These batteries can be customized in terms of shape and capacity according to customer requirements. Notably, prismatic lithium-ion cells boast enhanced cycle performance through material optimization and graphene conductive coating technology. BAK Battery has also improved low-temperature lithium ion conduction with new electrolyte additives, resulting in improved low-temperature performance for LFP products.

Of particular interest are the three large prismatic batteries on display, made from LFP + graphite materials, offering exceptional performance with ultra-high cell rated energy ranging from 320 Wh to 896 Wh. These batteries exhibit excellent continuous discharge capacity and durability, with a cycle life exceeding 8000 times and the ability to function reliably in extreme temperatures ranging from -20°C to +55°C. They can achieve peak charging currents of 100A to 150A, ensuring rapid charging and versatility across various applications, including base stations, home storage, small vehicle shops, power grid energy storage, and large vehicles.

Additionally, BAK showcased a 3U home storage unit with a rated total energy of 5120Wh, ideal for outdoor electricity consumption and household emergency preparedness. This unit incorporates protective features against overvoltage, undervoltage, overcurrent, low temperature, overtemperature, and short circuits, ensuring portability, durability, and safety for users.

As a vital component of the new energy industry chain's strategic layout, BAK Battery is committed to long-term investments, construction, and innovation in the energy storage sector. Their goal is to deliver high-quality, cost-effective, and safe products and solutions while contributing to the global energy storage industry's sustainable development and supporting China's efforts to achieve carbon neutrality and peak carbon dioxide emissions.
